Answers

Answer 1

The pattern of the data indicates a linear relationship or strong positive correlation between the average house prices and average monthly payments.

The monthly payment for a house costing $450,000 is $3,600.

A formulate connecting the average monthly payment with the average house price in slope-intercept form is y = 0.008x.

What is a proportional relationship?

In Mathematics, a proportional relationship can be represented by this equation:

y = kx

Where:

x represents the average house price.y represents the average monthly payment.k represents the constant of proportionality.

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 8/1000

Constant of proportionality (k) = 1/125 or 0.008.

Therefore, a formula that connects the two variables is given by;

y = kx

y = 0.008x

When average house price (x) = $450,000, the average monthly payment (y) is given by:

y = 0.008(450,000)

y = $3,600.

In conclusion, we can logically deduce that the pattern of the data shows a linear relationship or strong positive correlation between the average house prices (x) and average monthly payments (y) because as the average house prices (x) increases, the average monthly payments (y) also increases.

Answers

We are not given the distance between the spheres, so we cannot calculate the force without that information.

To calculate the electrostatic force between the two charged spheres, we can use Coulomb's law, which states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Mathematically, we can express this as:

F = k * (q1 * q2) / r^2

Where F is the electrostatic force, k is Coulomb's constant (9 x 10^9 N m^2/C^2), q1 and q2 are the charges of the spheres, and r is the distance between their centers.

We are given the charges of the two spheres: sphere A has a charge of +1.0 x 10^-6 C, and sphere B has a charge of -1.6 x 10^-6 C.

However, we are not given the distance between the spheres, so we cannot calculate the force without that information.

Para el periódico mural, los alumnos decidieron representar un pino por medio de un triángulo que tiene una superficie de 1. 5m si la base mide 1. 5 m ¿cuanto mide la altura? 

Answers

The height of the triangle is 2 meters.

How tall is triangle?

Para encontrar la altura del triángulo, podemos utilizar la fórmula para calcular el área de un triángulo:

Área = (base x altura) / 2

Sabemos que el área es de 1.5 m² y que la base mide 1.5 m, por lo que podemos despejar la altura de la siguiente manera:

1.5 m² = (1.5 m x altura) / 2

Multiplicando ambos lados por 2:

3 m² = 1.5 m x altura

Despejando la altura:

altura = 3 m² / 1.5 m

altura = 2 m

El 91 no es un número primo porque tiene más divisores que el 1 y el 91 verdadero o falso

Answers

The statement''El 91 no es un número primo porque tiene más divisores que el 1 y el 91''  is true because  91 is not a prime number.

A prime number is a positive integer that has only two divisors, 1 and itself. To check if 91 is a prime number, we need to find its divisors. We can start by dividing 91 by 2, but we find that 2 is not a divisor of 91. Next, we can try dividing it by 3, and we get 30 with a remainder of 1. This means that 3 is not a divisor of 91 either.

We continue dividing by 4, 5, 6, and so on until we reach 13, which gives us 7 as a quotient and 0 as a remainder. Therefore, the divisors of 91 are 1, 7, 13, and 91, which means that 91 is not a prime number because it has more than two divisors. Hence, the statement is true.

91 ÷ 2 = 45 r 1

91 ÷ 3 = 30 r 1

91 ÷ 4 = 22 r 3

91 ÷ 5 = 18 r 1

91 ÷ 6 = 15 r 1

91 ÷ 7 = 13 r 0

Since 91 has more than two divisors, it is not a prime number.

Two different box-filling machines are used to fill cerealboxes on the assembly line. The critical measurement influenced bythese machines is the weight of the product in the machines. Engineers are quite certain that the variance of the weight ofproduct is σ^2=1 ounce. Experiments are conducted using bothmachines with sample sizes of 36 each. The sample averages formachine A and B are xA=4. 5 ounces and xB =4. 7 ounces. Engineers seemed surprisedthat the two sample averages for the filling machines were sodifferent.


a. Use the central limit theorem to determine


P(XB- XA >= 0. 2)


under the condition that μA=μB


b. Do the aforementioned experiments seem to, in any way,strongly support a conjecture that the two population means for thetwo machines are different?

Answers

a. By central limit theorem, P(XB- XA >= 0. 2) is approximately 0.0228 under the condition that μA=μB.

b. Yes, we can conclude that the observed difference in sample means does provide evidence that the two population means for the two machines are different.

a. Using the central limit theorem, we know that the sampling distribution of the difference in means (XB - XA) is approximately normal with mean (μB - μA) and standard deviation (σ/√n), where σ is the population standard deviation (σ=1 ounce) and n is the sample size (n=36 for both machines).

So, P(XB - XA >= 0.2) can be calculated by standardizing the difference in means:

Z = (XB - XA - (μB - μA)) / (σ/√n)
Z = (4.7 - 4.5 - 0) / (1/√36)
Z = 2

Looking up the probability of Z being greater than or equal to 2 in a standard normal distribution table, we find P(Z >= 2) = 0.0228.

Therefore, P(XB - XA >= 0.2) is approximately 0.0228 under the condition that μA=μB.

b. The difference in sample means (XB - XA = 0.2) is relatively small compared to the population standard deviation (σ=1 ounce). However, the calculated probability in part a (0.0228) suggests that the observed difference in sample means is statistically significant at a significance level of 0.05 (since P(XB - XA >= 0.2) < 0.05).

Therefore, we can conclude that the observed difference in sample means does provide evidence that the two population means for the two machines are different. However, further testing or analysis may be necessary to confirm this conclusion.

pay? (Show your work)

Answers

Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.

To find Jesus' net bi-weekly pay, I followed these steps:

Calculate Jesus' commission: Jesus sold $16,200 of computer equipment, so his commission is 5.5% of $16,200, which is $891.

Calculate Jesus' gross bi-weekly pay: Jesus receives a bi-weekly salary of $300 plus his commission of $891, so his gross bi-weekly pay is $1,191.

Calculate Jesus' deductions: Jesus pays 8% for State Income Tax, 12.3% for Federal Income Tax, 6.3% for Social Security, and 1.45% for Medicare. To calculate the deductions, I multiplied his gross bi-weekly pay by each percentage rate:

State Income Tax: 8% of $1,191 = $95.28

Federal Income Tax: 12.3% of $1,191 = $146.67

Social Security: 6.3% of $1,191 = $75.09

Medicare: 1.45% of $1,191 = $17.27

Subtract the deductions from the gross bi-weekly pay: To find Jesus' net bi-weekly pay, I subtracted the total deductions of $334.31 from his gross bi-weekly pay of $1,191:

Net bi-weekly pay = $1,191 - $334.31 = $856.69

Therefore, Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.

An 8-inch-by-4-inch hole is cut from a
rectangular metal plate, leaving borders
of equal width x on all four sides. The
area of the metal that remains is 32 in².
The equation (8 + 2x)(4+2x) - 32 = 32
models the area of the plate. What is the
value of x, the frame width?

Answers

Answer:

2 inches

Step-by-step explanation:

The area of the metal plate can be calculated by subtracting the area of the hole from the area of the original plate. The area of the original plate is:

8 inches x 4 inches = 32 square inches

The area of the hole is:

8 inches x 4 inches = 32 square inches

So the area of the metal that remains is:

32 square inches - 32 square inches = 0 square inches

According to the equation given, we know that:

(8 + 2x)(4 + 2x) - 32 = 32

Expanding this equation we get:

32 + 16x + 8x + 4x^2 - 32 = 32

Simplifying and rearranging we get:

4x^2 + 24x - 32 = 0

Dividing both sides by 4 we get:

x^2 + 6x - 8 = 0

We can solve this quadratic equation by factoring:

(x + 4)(x - 2) = 0

So x = -4 or x = 2. Since the width of the frame cannot be negative, the only valid solution is x = 2.

Therefore, the frame width is 2 inches.

Find an equation of the plane that passes through the given point and is perpendicular to the given vector or line.
Point (0, 9, 0) Perpendicular to
n = -2i ÷ 4k

Answers

To find the equation of the plane that passes through the point (0, 9, 0) and is perpendicular to the vector n = -2i ÷ 4k, we first need to find the normal vector of the plane.

Since the plane is perpendicular to the given vector, the normal vector will be parallel to it. So, we can take the given vector and multiply it by -1 to get a vector in the opposite direction, which will be normal to the plane.

n = -2i ÷ 4k = -1/2i ÷ k

Multiplying by -1 gives us:

n = 1/2i ÷ k

Now we can use the point-normal form of the equation of a plane:

r · n = d

where r is the position vector of any point on the plane, n is the normal vector, and d is the distance of the plane from the origin (since the normal vector is normalized, d will be the signed distance of the plane from the origin).

Substituting the given point (0, 9, 0) and the normal vector n = 1/2i ÷ k into the equation, we get:

(0, 9, 0) · (1/2i ÷ k) = d

0 + 9(1/2) + 0 = d

d = 4.5

So the equation of the plane is:

Step-by-step explanation:To solve the quadratic equation 6x²-11x-35= 0, we can use the quadratic formula:

x = (-b ± sqrt(b² - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation.

In this case, we have:

a = 6

b = -11

c = -35

Substituting these values into the quadratic formula, we get:

x = (-(-11) ± sqrt((-11)² - 4(6)(-35))) / 2(6)

Simplifying this expression:

x = (11 ± sqrt(121 + 840)) / 12

x = (11 ± sqrt(961)) / 12

x = (11 ± 31) / 12

So, we have two solutions:

x = (11 + 31) / 12 = 3

and

x = (11 - 31) / 12 = -5/2

Express the grower's total yield as a function of the number of additional trees planted, draw the graph and estimate the total number of trees the grower should plant to maximize yield.

Answers

Answer: 80 trees

Step-by-step explanation:

YIELD = (NUMBER OF TREES)*(NUMBER OF ORANGES PER TREE)

Let's assume NUMBER OF TREES = 60 + x, where x is the number of additional trees above 60

The NUMBER OF ORANGES PER TREE will = (400-4x).  Hence:

YIELD = (60+x)*(400-4x) = 24000-240x+400x-4x2 = -4x2 + 160x + 24,000

To find the maximum YIELD, take the derivative of YIELD wrt x, set it to zero, and solve for x:

d(YIELD)/dx = -8x + 160

Find the smallest number of terms of the series ∑ n = 1 (-1)^n+1/2^n you need to be certain that the partial sum Sn is within 1/100 of the sum.n=2 n=4 n=6 n=8 n=7

Answers

We need at least 7 terms of the series to be certain that the partial sum Sn is within 1/100 of the sum.

We want to find the smallest value of n such that the absolute value of the difference between the sum of the first n terms and the sum of the entire series is less than 1/100.

The sum of the first n terms of the series is given by:

Sn = ∑_(k=1[tex])^n[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex]

We can write the sum of the entire series as:

S = ∑_(k=[tex]1)^∞[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex]

The absolute value of the difference between the sum of the first n terms and the sum of the entire series is:

|S - Sn| = |∑_(k=n+1[tex])^∞[/tex] [tex](-1)^(k+1)/2^k|[/tex]

We want to find the smallest value of n such that |S - Sn| < 1/100.

Let's start by evaluating the sum of the series:

S = ∑_(k=1) (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex] = 1/2 - 1/4 + 1/8 - 1/16 + ...

This is a geometric series with first term a = 1/2 and common ratio r = -1/2. The sum of the series is:

S = a/(1-r) = (1/2)/(1+1/2) = 1/3

Now we can write:

|S - Sn| = |∑_(k=n+1[tex])^∞[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k|[/tex] <= 1/[tex]2^(n+1)[/tex]

The last inequality is true because the terms of the series are decreasing in absolute value, and we are summing an infinite number of terms.

Therefore, we need to find the smallest value of n such that 1/2^(n+1) < 1/100. This gives:

n+1 > log2(100)

n > log2(100) - 1

n > 6.64

The smallest integer value of n that satisfies this inequality is n = 7.

Therefore, we need at least 7 terms of the series to be certain that the partial sum Sn is within 1/100 of the sum.

The fifth and tenth terms of an arithmetic sequence,


respectively, are -2 and 53. What is the seventh


term of the sequence?

Answers

If the fifth and tenth terms of an arithmetic sequence, respectively, are -2 and 53, the seventh term of the arithmetic sequence is 20.

To find the seventh term of the arithmetic sequence, we need to first find the common difference (d) of the sequence. We know that the fifth term is -2 and the tenth term is 53.

The formula for the nth term of an arithmetic sequence is: an = a1 + (n-1)d

Using this formula, we can set up two equations:

-2 = a1 + 4d  (since the fifth term is a1 + 4d)
53 = a1 + 9d  (since the tenth term is a1 + 9d)

We now have two equations with two variables (a1 and d). We can solve for either variable using substitution or elimination. I'll use elimination:

-2 = a1 + 4d
53 = a1 + 9d

Subtracting the first equation from the second equation, we get: 55 = 5d

Therefore, d = 11

Now that we know the common difference is 11, we can use the formula for the nth term again to find the seventh term:

a7 = a1 + (7-1)d
a7 = a1 + 6d

We still don't know a1, but we can solve for it using one of the previous equations:

-2 = a1 + 4d
-2 = a1 + 4(11)
-2 = a1 + 44
a1 = -46

Now we can substitute a1 and d into the formula for the seventh term:

a7 = -46 + 6(11)
a7 = -46 + 66
a7 = 20

Therefore, the seventh term of the arithmetic sequence is 20.

Vanessa's team played 8 games of basketball. During those 8 games her team's score was: 68, 76, 63, 58, 64, 75, 78 and 78.



What is the mean absolute deviation?



Please help!! Please answer it correctly too!!!! Whoever gets it correct gets brainliest!! and then I will give them 154 points!!!! please!!

Answers

The mean absolute deviation is 6.25.

To find the mean absolute deviation (MAD), we first need to find the mean of the scores:

Mean = (68 + 76 + 63 + 58 + 64 + 75 + 78 + 78) / 8 = 69.5

Next, we need to find the absolute deviation of each score from the mean. The absolute deviation is the absolute value of the difference between the score and the mean.

For example, the absolute deviation of the first score (68) is:

|68 - 69.5| = 1.5

We can calculate the absolute deviation for each score:

|68 - 69.5| = 1.5

|76 - 69.5| = 6.5

|63 - 69.5| = 6.5

|58 - 69.5| = 11.5

|64 - 69.5| = 5.5

|75 - 69.5| = 5.5

|78 - 69.5| = 8.5

|78 - 69.5| = 8.5

To find the MAD, we take the average of the absolute deviations:

MAD = (1.5 + 6.5 + 6.5 + 11.5 + 5.5 + 5.5 + 8.5 + 8.5) / 8 = 6.25

Therefore, the mean absolute deviation is 6.25.

Find the height of a cone with a diameter of 12m whose volume is 226m3. Use 3. 14, and round your answer to nearest meter

Answers

The height of a cone with a diameter of 12m whose volume is 226m³ is 6 meters.

The formula for the volume of a cone is

V = (1/3) * π * r^2 * h

where V is the volume, r is the radius, h is the height, and π is approximately equal to 3.14.

We know the diameter of the cone is 12m, which means the radius is 6m.

We also know that the volume of the cone is 226m^3.

Substituting these values into the formula, we get:

226 = (1/3) * π * 6^2 * h

Simplifying:

226 = (1/3) * 3.14 * 36 * h

226 = 37.68h

h = 226/37.68

h ≈ 6

Therefore, the height of the cone is approximately 6 meters.

Taylor would like to have a karaoke deejay at her graduation party. her three sisters volunteered to split the cost of hiring the deejay. they need to rent a tent for $45 and a microphone system for $60 and then pay the deejay $30 an hour for four hours. how much do each of the sisters owe?

write out all the work used to determine the answer to the question.

Answers

Each of the three sisters owes $75 to cover the cost of hiring the karaoke deejay for Taylor's graduation party.

To determine how much each sister owes, we need to first calculate the total cost of the party and then divide that cost by three, since there are three sisters splitting the cost.

1. Tent rental: $45
2. Microphone system: $60
3. Deejay cost: $30/hour × 4 hours = $120

Now, we'll add these costs together to find the total cost:
Total cost = $45 (tent) + $60 (microphone) + $120 (deejay) = $225

Finally, we'll divide the total cost by the number of sisters (3) to find out how much each sister owes:
Amount owed per sister = $225 (total cost) ÷ 3 (sisters) = $75

So, each sister owes $75 for the karaoke deejay at Taylor's graduation party.

Find the equation of the tangent line at (6, f(6)). y =

Answers

The equation of the tangent line at (6, f(6)) is y = 6x - 48.

a. The slope of the secant line joining (2, f(2)) and (7, f(7)) is:

slope = (f(7) - f(2)) / (7 - 2)

We can find f(7) and f(2) by plugging in x = 7 and x = 2 into the expression for f(x):

f(7) = 7² - 6(7) = 7

f(2) = 2² - 6(2) = -8

Substituting these values into the slope formula, we get:

slope = (7 - (-8)) / (7 - 2) = 3

Therefore, the slope of the secant line joining (2, f(2)) and (7, f(7)) is 3.

b. The slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)) is:

slope = (f(6 + h) - f(6)) / ((6 + h) - 6) = (f(6 + h) - f(6)) / h

We can find f(6) and f(6 + h) by plugging in x = 6 and x = 6 + h into the expression for f(x):

f(6) = 6² - 6(6) = -12

f(6 + h) = (6 + h)² - 6(6 + h) = h² - 6h + 36 - 36 - 6h = h² - 12h

Substituting these values into the slope formula, we get:

slope = (h² - 12h - (-12)) / h = h - 12

Therefore, the slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)) is h - 12.

c. The slope of the tangent line at (6, f(6)) is the derivative of f(x) at x = 6:

f'(x) = 2x - 6

f'(6) = 2(6) - 6 = 6

Therefore, the slope of the tangent line at (6, f(6)) is 6.

d. To find the equation of the tangent line at (6, f(6)), we use the point-slope form of a line:

y - f(6) = f'(6)(x - 6)

Substituting f(6) and f'(6) into this equation, we get:

y - (-12) = 6(x - 6)

Simplifying, we get:

y = 6x - 48

Therefore, the equation of the tangent line at (6, f(6)) is y = 6x - 48.
