The daily high temperatures in degrees Fahrenheit in Allentown, PA, for a period of 10 days are shown below. 76 80 89 96 98 100 98 91 89 82 Which statement correctly describes the data?
A the median value is 98
B the upper quartile value is 96
C the lower quartile vlue is 76
d the interquartile range is 16​

Answers

Answer 1

Answer:

the only correct statement is B: the upper quartile value is 96.

Step-by-step explanation:

First, let's put the temperatures in order: 76, 80, 82, 89, 89, 91, 96, 98, 98, 100.

A. To find the median, we need to find the middle value in the ordered set of data. Since there are an even number of values, we take the average of the two middle values. The two middle values are 89 and 91, so the median is (89+91)/2 = 90. Therefore, statement A is false.

B. To find the upper quartile, we need to find the value that separates the highest 25% of the data from the rest. Since there are 10 values, the upper quartile is the 7th value when the data is ordered. The 7th value is 96, so statement B is true.

C. To find the lower quartile, we need to find the value that separates the lowest 25% of the data from the rest. Since there are 10 values, the lower quartile is the 3rd value when the data is ordered. The 3rd value is 82, so statement C is false.

D. The interquartile range is the difference between the upper quartile and the lower quartile. From our previous calculations, we know that the upper quartile is 96 and the lower quartile is 82. Therefore, the interquartile range is 96-82 = 14. Statement D is false.

Therefore, the only correct statement is B: the upper quartile value is 96.

What is the product of two factors?

We know that the product of two factors is equal to zero only when at least one of the factors is zero.

[tex](x + 4) \ (2x - a) = 0[/tex]

This equation has two factors:  [tex](x + 4)[/tex] and [tex](2x - a)[/tex] . We can set each of these factors equal to zero and solve for x to find the values that make the equation true.

Setting  [tex](x + 4)[/tex] equal to zero, we get:

[tex]x + 4 = 0[/tex]

[tex]x = -4[/tex]

This means that  [tex]-4[/tex] is one of the solutions of the equation.

Setting  [tex](2x - a)[/tex] equal to zero, we get:

[tex]2x - a = 0[/tex]

[tex]2x = a[/tex]

[tex]x = a/2[/tex]

This means that [tex]a/2[/tex] is another solution of the equation.

Since we know that the equation has the solutions  [tex]x = 4[/tex] and [tex]x = -4[/tex]  , we can substitute these values into the expression we found for x in terms of a to get:

[tex]a/2 = 4[/tex] or  [tex]a/2 = -4[/tex]

Solving for a in each case, we get:

[tex]a = 8[/tex] or [tex]a = -8[/tex]

Therefore, the value of a could be either  [tex]8[/tex] or  [tex]-8[/tex] .

i need to know the length of side EF and side FG

Answers

The lengths of EF and FG to the nearest tenth are approximately 10.2 and 5.8, respectively.

What are the lengths?

To solve this problem, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides.

Let's start by finding the measure of ∠G, using the fact that the sum of the angles in a triangle is 180 degrees:

m∠G = 180° - m∠E - m∠F = 180° - 39° - 86° = 55 °

Now we can use the Law of Sines to find the lengths of EF and FG:

EF/sin(F) = EG/sin(G)

EF/sin(86) = 7.9/sin(55)

EF = sin(86)*7.9/sin(55) ≈ 10.2

Similarly,

FG/sin(E) = EG/sin(G)

FG/sin(39) = 7.9/sin(55)

FG = sin(39)*7.9/sin(55) ≈ 5.8

Therefore, the lengths of EF and FG to the nearest tenth are approximately 10.2 and 5.8, respectively.

Mary is 3 times as old as her son. In 12 years Mary will ve twice as old as her son. How old are each of them now

Answers

Let's assume the age of Mary's son as "x".

According to the given information, Mary is 3 times as old as her son. So, Mary's age will be 3x.

Also, given that in 12 years Mary will be twice as old as her son.

So, after 12 years, Mary's age will be (3x + 12) and her son's age will be (x + 12).

According to the given information,

3x + 12 = 2(x + 12)

3x + 12 = 2x + 24

3x - 2x = 24 - 12

x = 12

Therefore, Mary's son is 12 years old now.

And, Mary's age is 3x = 3(12) = 36 years.

Hence, Mary is 36 years old and her son is 12 years old.

Answer:

Mary is 36 years old

Her son is 12 years old

Step-by-step explanation:

Let's assume, that Mary's son is x years old and Mary is 3x years old

Let's write 2 equations according to the given information:

x = 3x (Mary is 3 times older than her son)

3x + 12 = 2(x + 12) (after 12 years, she will be 2 times older than her son)

3x + 12 = 2x + 24

3x - 2x = 24 - 12

x = 12

That means, Mary's son is 12 years old

Mary is 3 × 12 = 36 years old

rovide an example of when you might want to take a systematic random sample instead of a simple random sample, and explain what the advantages of a systematic random sample might be

Answers

A stratified random sample is preferred when the population is heterogeneous, ensuring a proportional representation of each subgroup, and allowing for more accurate comparisons and reliable inferences about the population.

When the community under study is heterogeneous, which means it can be broken down into different divisions or sectors, a stratified random sample is usually favored over a basic random sample.

In this situation, a stratified random sample makes it possible for each stratum to be proportionally reflected in the sample, guaranteeing that each subset is properly represented. When analyzing the differences or parallels between various subgroups, this method can be especially helpful.

For instance, a business might want to poll to find out how satisfied customers are with its offerings. They might choose to select a stratified random sample based on customer demographic categories or regions as opposed to a straightforward random sample.

Let's factor this the "old fashioned" way. The standard form of a quadratic is

[tex]y=ax^2+bx+c[/tex]

If you're familiar with the quadratic formula I'd say throw it into that, but if not, again, let's do it the "old fashioned" way.  

We need to find the product of our a and c. Our a = 2 and our c = -3. So that gives us a -6. Now we have to find the factors of 6 (the negative right now doesn't matter so much). The factors of 6 are 1, 6  and 2, 3.  Both of those possibilities will work to give us a +5, which is the linear term. Putting in the 2, 3 first:

[tex]0=2x^2+3x+2x-3[/tex]

Now group the terms together into groups of 2:

[tex]0=(2x^2+3x)+(2x-3)[/tex]

The idea is to factor out something common in each term so that what's left over in the parenthesis in both terms is exactly the same.  In the first term we can factor out a common x, and in the second term, the only thing common is a 1.  So that looks like this:

[tex]x(2x+3)+1(2x-3)[/tex]

What's inside those parenthesis are not actually identical, so 2 and 3 won't work.  Lets try 1 and 6.  For those 2 numbers to equal a +5, the 6 is positive and the 1 is negative.  So let's try that:

[tex](2x^2+6x)+(-x-3)[/tex]

In the first term we can factor out the common 2x and in the second term we can factor out the common -1:

[tex]2x(x + 3) - 1(x + 3)[/tex]

Now what's common is [tex](x + 3)[/tex], so we can factor THAT out and what is left over is [tex]2x - 1[/tex]:

[tex](x + 3)(2x - 1) = 0[/tex]

If [tex]x + 3 = 0[/tex], then [tex]\bold{x = -3}[/tex]

and if [tex]2x - 1 = 0[/tex], then [tex]2x = 1[/tex] and [tex]\bold{x = \frac{1}{2} }[/tex]

Answers

The temperature should be 99.471° F.  If we want only 2.0% of healthy people.

Given that:

μ = 98.20

σ = 0.62

Determine the z-score in the normal probability table in the appendix that corresponds with a probability of:

1 − 0.02 =0.98

It is calculated by subtracting the population mean from the individual raw scores and dividing the difference by the population standard deviation. The process of converting raw scores to standardized scores is called standardization or normalization (although "normalization" can refer to different types of comparisons; see Normalization for more information).

The standardized score is the value x decreased by the mean and then divided by the standard deviation:

​     Z = X - μ / σ

⇒ x = μ+ zσ

      = 98.20+ (2.05)(0.62) = 99.471

why might a repeated-measures study require half the number of subjects compared to a similar matched-subjects study with the same number of scores?

Answers

The repeated measures studies require fewer subjects than matched subjects studies with the same number of outcomes is that repeated measures designs reduce intersubject variability.

In repeated measures studies, each participant is measured multiple times under different conditions or treatments.

Whereas, In a matched-subjects study, each participant in the treatment group is compared to participants in the control group.

Intersubject variability can be large, and differences between treatment and control groups may be attributed to differences in these individual characteristics.

However, in a repeated-measures design, each participant served as its own control, reducing inter-subject variability.

This makes it easier to recognize differences in treatment conditions and can increase effect sizes.

Therefore, a repeated measures study may require fewer subjects to achieve the same statistical power as a matched subjects study with the same number of outcomes.

However, it is important to note that repeated measures designs may have their own limitations:  Potential Order Effect or Practice Effect.

These limitations should be carefully considered when designing a study, and an appropriate design should be chosen based on the research question and the nature of the data.

A. 6 old printers would produce the batch of magazines in less time than 2 new printers
B.
Using 6 old printers would produce the batch of magazines in 5 minutes, which is 25 minutes faster than using 5 old printers

EXPLANATIONS:

a) To determine which option would produce a batch of magazines in less time, we need to compare the printing rates of each option.

The old printers can produce a batch of magazines in 30 minutes, which means their printing rate is:

5 printers / 30 minutes = 1/6 printers per minute

The new printers can produce the same batch of magazines in 16 minutes, which means their printing rate is:

4 printers / 16 minutes = 1/4 printers per minute

If we use 6 old printers, their printing rate would be:

6 printers / 30 minutes = 1/5 printers per minute

If we use 2 new printers, their printing rate would be:

2 printers / 16 minutes = 1/8 printers per minute

Therefore, 6 old printers would produce the batch of magazines in less time than 2 new printers.

b) To determine how much less time it would take to produce the batch of magazines with 6 old printers, we can set up a proportion:

1/5 printers per minute = 1/x minutes

Solving for x, we get:

x = 5 minutes

Therefore, using 6 old printers would produce the batch of magazines in 5 minutes, which is 25 minutes faster than using 5 old printers.

An algebraic expression is a mathematical phrase that can include numbers, variables, and operators (such as addition, subtraction, multiplication, and division), as well as grouping symbols like parentheses.

The given equation is:

x³ = -216/343

To solve for x, we can take the cube root of both sides of the equation:

∛(x³) = -∛(216/343)

x = -∛(216/343)

Solving for numerator:

216 =  6 × 6 × 6

∛216 = 6

Solving for denominator:

343 = 7 × 7 × 7

∛343  = 7

Therefore,

x = -∛(216/343)

x = -(6/7)

x = -6/7

Putting the negative sign to the numerator, we have the value of x = -6/7.

The volume of a sphere can be found using the equation:

V = 4/3 pi r^3

Since we are only given the diameter and not the radius, we must divide the diameter by 2 to get the radius:

5 / 2 = 2.5 or 5/2

now plug this into the volume equation:

V = 4/3 pi (5/2)^3

Solve this in steps:

(5/2)^3 = 125/8

Multiply this by 4/3:

4/3 • 125/8 = 125/6

Now times pi:

125/6 • pi = 125pi/6 cm^3

And simplified:

65.45 cm^3

Your answers are:

Exact: 125pi/6 cm^3
Approx: 65.45 cm^3

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 12 feet and a height of 10 feet. Container B has a diameter of 8 feet and a height of 17 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full.

Triangle ABC is shown. Use the graph to answer the question.
Determine the coordinates of the image if triangle ABC is translated 5 units down
OA(-4,-2), B(4,-2). C'(0, 2)
OA(1, -7), 8(9,-7). C'(5,-3)
OA(1, 3), B(9, 3), C'(5, 7)

Answers

To translate a figure 5 units down, we need to subtract 5 from the y-coordinates of all the vertices of the triangle.

Given that A(-4, -2), B(4, -2), and C(0, 2), the new coordinates of the vertices after the translation are:

A' = (-4, -2 - 5) = (-4, -7)
B' = (4, -2 - 5) = (4, -7)
C' = (0, 2 - 5) = (0, -3)

Therefore, the coordinates of the image of triangle ABC after it is translated 5 units down are A'(-4, -7), B'(4, -7), and C'(0, -3).

So, option B (A(1, -7), B(9,-7), C'(5,-3)) is the closest match to the image after the translation

This is used to calculate the height of the object at any time t during its flight.

The equation you provided represents the height of an object (in meters) at time t (in seconds) when it is thrown or projected upward with an initial velocity of v (in meters per second) from an initial height of hi (in meters) above the ground.

The acceleration due to gravity is taken to be -9.8 m/[tex]s^2[/tex] (negative since it acts downward), and the formula for the height is derived from the equation of motion:

h(t) = -1/2 [tex]gt^2[/tex] + vt + hi

Where:

g = 9.8 m/[tex]s^2[/tex] (acceleration due to gravity)

t = time (in seconds)

v = initial velocity (in meters per second)

hi = initial height (in meters)

The coefficient -4.9 in the equation you provided is simply half of the acceleration due to gravity (-9.8/2 = -4.9).

This is because the object is thrown upward and experiences a deceleration due to gravity that decreases its upward velocity by 9.8 m/[tex]s^2[/tex] until it reaches the maximum height and then starts to fall back down.

So, for any given initial velocity and height, this equation can be used to calculate the height of the object at any time t during its flight.
