The probability is P = 0.51, and the odds are 15 to 14.

If all the ties have the same probability of being randomly choosen, then the probability of randomly selecting a tie that goes well with the sports coat is equal to the quotient between the number of ties that goes well with the sports coat (15) and the total number of ties.

The probability will be:

P = 15/29 = 0.51

And the odds are the number of good ties to the number of the other ones, there are 15 good ones and 14 bad ones, so the odds are 15 to 14.

Answer:

C. (x + 3)² + (y - 4)² = 9

Step-by-step explanation:

The equation for a circle is r² = (x - a)² + (y - b)² where "r" is the radius and (a, b) is the center.

We are given that (-3, 4) is the center and the radius is 3, so that means a = -3, b = 4, and r = 3. Insert the values to their respective places in the equation:

3² = (x - (-3))² + (y - 4)²

9 = (x + 3)² + (y - 4)²

Answer:

equation of a circle: (x-a)²+(y-b)²=r²

(x-(-3))²+(y-4)²=3²

(x+3)²+(y-4)²= 9

(x+6x+9)+(y-8y+16) =9

x+6x+9+y-8y+16=9

x+y+6x-8y+9+16-9=0

Step-by-step explanation:

we cannot conclude that the volume of the prism is half the volume of the cylinder, twice the volume of the cylinder, or not equal to the volume of the cylinder.

How to solve the problem ?

The given information states that the cross-sectional areas of a triangular prism and a right cylinder are congruent, and both have a height of 5 units. Based on this information, we can conclude that the volumes of the two shapes may be equal, but we cannot conclude that the volume of the prism is half or twice the volume of the cylinder.

To determine the volumes of the two shapes, we need to know their respective formulas. The volume of a triangular prism is given by V = (1/2)bh, where b is the length of the base of the triangular cross-section and h is the height of the prism. The volume of a right cylinder is given by V = πr²h, where r is the radius of the circular cross-section and h is the height of the cylinder.

Since the cross-sectional areas of the two shapes are congruent, we can assume that their bases are similar. Therefore, the base of the triangular prism must be a triangle with the same area as the circular base of the cylinder. However, without further information about the shape and size of the cross-section, we cannot determine the values of b and r.

Therefore, we cannot conclude that the volume of the prism is half the volume of the cylinder, twice the volume of the cylinder, or not equal to the volume of the cylinder. The only conclusion that can be made is that the volume of the prism is equal to the volume of the cylinder, assuming that the cross-sectional areas are congruent.

Answer:

a quotient is the result obtained by dividing one quantity by another.

1. The linear regression equation is y = -1.17x+ 10.69

2. The correlation coefficient is -0.982.

3. This means there is a strong negative correlation between the gallons and hours.

4. The number of gallons is decreasing as the hours are increasing.

Step 1: find slope.

Formula for slope m = (n × Σ(xy) - Σx × Σy) / (n × Σ(x²) - (Σx)²)

Σx = 1 + 2 + 3 + 4 + 5 = 15

Σy = 9.2 + 8.4 + 7.7 + 6.1 + 4.5 = 35.9

Σ(xy) = (1 × 9.2) + (2 × 8.4) + (3 × 7.7) + (4 × 6.1) + (5 × 4.5) = 96

Σ(x²) = 1 + 4 + 9 + 16 + 25 = 55

n = 5

Therefore ∴

m = (5 × 96 - 15 × 35.9) / (5 × 55 - 15²) = -1.17

y-intercept b = (Σy - m × Σx) / n

b = (35.9 - (-1.17) × 15) / 5 = (53.15) / 5 = 10.63

Therefore the linear regression equation is y = -1.17x + 10.63

correlation coefficient (r): (n × Σ(xy) - Σx × Σy) / sqrt((n × Σ(x²) - (Σx)²) × (n × Σ(y²) - (Σy)²))

r = (5 × 96 - 15 × 35.9) / sqrt((5 × 55 - 15²) × (5 × 271.95 - 35.9²)) = -0.982

Step-by-step explanation: They are not perpendicular due to the slopes. Perpendicular will have the same slopes value wise, but one is negative and one positive.

the correct expression which can also be used to determine the total time needed to cook x batches of boiled cornbread is,

B) 10x + 10x + 20 - 5.

Given that;

The expression 20x + 15 represents the total time needed to cook x batches of boiled cornbread.

We can simplify this expression by factoring out the common factor of 5: = 20x + 15

= 5(4x + 3)

Therefore, the expression that can also be used to determine the total time needed to cook x batches of boiled cornbread must have a factor of 5 in it.

Option A:

18x + 4x + 6 + 7 does not have a factor of 5,

so it cannot be the correct answer.

Option B:

10x + 10x + 20 - 5

= 20x + 15,

which is the same as the original expression.

Therefore, Option B is equivalent to the original expression and can also be used to determine the total time needed to cook x batches of boiled cornbread.

Option C:

6(5x + 5) - 10x + 15 = 30x + 15 - 10x + 15 = 20x + 30,

which does not have a factor of 5.

Therefore, Option C is not correct.

Option D:

3(x + x + x + 3) + 2x + 15 = 9x + 6 + 2x + 15 = 11x + 21,

which does not have a factor of 5.

Therefore, Option D is not correct.

Therefore, the correct answer is,

B) 10x + 10x + 20 - 5.

Dice game for a particular child’s game are numbered 1-10. Then, the  likelihood of rolling a single one and ending up with an even number is 1/20.

The probability of rolling a single one is 1/10, since there is only one die face with the number one out of ten possible outcomes.

The probability of rolling an even number is 5/10, since half of the die faces are even numbers (2, 4, 6, 8, 10) out of ten possible outcomes.

To find the likelihood of both events happening together, we need to multiply their individual probabilities;

P(rolling a single one and ending up with an even number) = P(rolling a single one) x P(ending up with an even number)

Step-by-step explanation:

The row of zeros at the bottom immediately lets us conclude "infinitely many solutions". This system is consistent and dependent. This is because we have 0x+0y+0z = 0 aka 0 = 0 which is always true for any choice of x, y, and z.

The second row of values lead to the equation 0x+0y+1z = 6, aka z = 6

The first row says: 1x+6y+0z = 1 which is the same as x+6y = 1

Let's say we isolate x

x+6y = 1

x+6y-6y = 1-6y

x = 1-6y

Then we have these three values or expressions

All of the infinitely many solutions are of the form (x,y,z) = (1-6y, y, 6)

A lot of textbooks will use a parameter such as t, so we could write it as (1-6t, t, 6).

The choice of the letter for the parameter does not matter. I think t is most popular because it represents time. Each (x,y,z) point could represent a particle's location at any given time.

and so on.

=============================

Conclusion:

There are infinitely many solutions of the form (x,y,z) = (1-6t, t, 6) where t is any real number.

This system is consistent and dependent.

The equation of the axis of symmetry of the given quadratic function is x = -2. So, correct option is C.

The axis of symmetry of a parabola is a vertical line that passes through the vertex of the parabola. For a quadratic function in the form y = ax² + bx + c, the equation of the axis of symmetry is given by x = -b/(2a).

In the given equation, y = 2x² + 8x - 3, the coefficients of x² and x are a = 2 and b = 8, respectively. Substituting these values in the equation of the axis of symmetry, we get:

x = -b/(2a)

x = -8/(2*2)

x = -8/4

x = -2

This means that the parabola is symmetric about the vertical line x = -2. So the correct answer is x=-2.

If the value of a certain collectible card in dollars from January 2020 to May 2021 can be modeled by the function V(m)=250m² – 3,500m + 18,000, the value of the card was declining over the period 0 < m < 7.

To determine when the value of the collectible card was declining, we need to look for when the first derivative of the function is negative. If the first derivative of the function is negative over a certain period, then the function is decreasing over that period. The first derivative of the function V(m) is:

V'(m) = 500m - 3,500

To find when the value of the card was declining, we need to solve the inequality V'(m) < 0. Solving for m, we get:

500m - 3,500 < 0

500m < 3,500

m < 7

Therefore, the value of the card was declining over the period 0 < m < 7. This corresponds to the months from January 2020 to July 2020. During this period, the first derivative of the function V(m) is negative, which means the value of the card was decreasing.

Answer:$909.03

Step-by-step explanation:he new balance on Guadalupe's credit card is calculated as follows:

First, we calculate the interest charged on the previous balance. Since the APR is 23%, the monthly interest rate is 23%/12 = 1.92%. So the interest charged on the previous balance for the month is:

Interest = Previous balance x Monthly interest rate

= $900.00 x 1.92%

= $17.28

Next, we add the finance charge, which is calculated as 1% of the previous balance plus any new charges. So the finance charge for the month is:

Finance charge = 1% x (Previous balance + New charges)

= 1% x ($900.00 + $0.00)

= $9.00

The total amount due is the sum of the previous balance, the interest charged, and the finance charge:

Total amount due = Previous balance + Interest + Finance charge

= $900.00 + $17.28 + $9.00

= $926.28

The minimum payment due is 2% of the total amount due, which is:

Minimum payment = 2% x Total amount due

= 2% x $926.28

= $18.53

If the minimum payment is less than $25, the minimum payment due is $25. So in this case, the minimum payment due is $25.

Guadalupe made a payment of $18.00, which is less than the minimum payment due, so she will be charged a late fee in addition to the interest on the unpaid balance.

The principal paid is the difference between the payment made and the interest charged, which is:

Principal paid = Payment - Interest

= $18.00 - $17.28

= $0.72

The new balance is the sum of the previous balance, any new charges, and the interest charged, minus the payment made, plus any finance charge and late fee:

New balance = Previous balance + New charges + Interest - Payment + Finance charge + Late fee

= $900.00 + $0.00 + $17.28 - $18.00 + $9.00 + $0.75

Answer:

10 wax cubes

Step-by-step explanation:

the volume of the square pyramid can be found by using the following formula:

[tex]V = \frac{1}{3} * B * h[/tex]

where b is the base of the pyramid and h is the height of the pyramid

The area of the base of the pyramid is given as 12 in * 12 in = 144 in^2

So, the volume of the pyramid is:

V = (1/3) * 144 in^2 * 14 in = 2,016 in^3

Each wax cube has a volume of 6 in * 6 in * 6 in = 216 in^3.

To find the number of wax cubes needed, we can divide the volume of the pyramid by the volume of each wax cube:

Number of wax cubes = Volume of pyramid / Volume of each wax cube

Number of wax cubes = 2,016 in^3 / 216 in^3

Number of wax cubes = 9.33 (rounded to two decimal places)

Since we can't have a fraction of a wax cube, Josiah will need to use 10 wax cubes to make the candle.

x = 5

Step-by-step explanation:

To solve the equation 4x-8 + 4 = 16, we first combine the constants on the left-hand side:

4x-8+4 = 16

4x-4 = 16

Next, we add 4 to both sides to isolate the variable on one side:

4x-4+4 = 16+4

4x = 20

Finally, we divide both sides by 4 to solve for x:

4x/4 = 20/4

x = 5

Therefore, the solution to the equation 4x-8 + 4 = 16 is x = 5.
