The diameter of the circle is also 7.5 units.

We have,

The radius of a circle is half of its diameter.

Given that the circle has a diameter of 7.5, we can find the radius by dividing the diameter by 2:

Radius

= diameter/2

= 7.5/2

= 3.75

The radius of the circle is 3.75 units.

The diameter of the circle is twice the radius.

Diameter = 2 x radius = 2 x 3.75 = 7.5

Thus,

The correct options are C and D.

Let's describe the variables for our system:

x = cost of a can of paint.

y = cost of a brush.

We know that the total cost is $104, then one of the equations is:

4x + 3y = 104

And we know that the cost of a can is $4 more than the double of a brush, then the other equation is:

The results of the two-sample t-test, there does not appear to be enough evidence to support the claim that the mean FICO score of borrowers with high-interest mortgages is different than the mean FICO score of borrowers with low-interest mortgages.

To test the claim that the mean FICO score of borrowers with high-interest mortgages is different than the mean FICO score of borrowers with low-interest mortgages, we can perform a two-sample t-test.

Using the given data, we can calculate the test statistic as follows:

t = (492 - 508) / sqrt((49^2 / 19) + (38^2 / 26)) = -1.57

The degrees of freedom for this test are 19 + 26 - 2 = 43. Using a t-table or calculator and a significance level of 0.2, we can find the critical value to be approximately ±1.301.

Since the absolute value of the test statistic (1.57) is less than the critical value (1.301), we fail to reject the null hypothesis. This means that we do not have enough evidence to support the claim that the mean FICO score of high-interest mortgage borrowers is different than the mean FICO score of low-interest mortgage borrowers at the 0.2 significance level.

The measure of the angle ABC is 84 degrees and other measures are listed below

Here, we have

8n - 38 = 5n - 8

So, we have

3n = 30

n = 10

So, we have

ABC = 8n - 38 + 5n - 8

ABC = 8(10) - 38 + 5(10) - 8

ABC = 84

So, the measure of the angle ABC is 84 degrees

Here, we have

2k + 28 = 6k - 20

So, we have

4k = 8

k = 2

So, we have

CBW = 2k + 28

CBW = 2(2) + 28

CBW = 32

So, the measure of the angle CBW is 32 degrees

The interior angle is calculated as

Angle = 180 * (n - 2)/n

Regular 18-gon

Angle = 180 * (18 - 2)/18

Angle = 160

Regular 24-gon

Angle = 180 * (24 - 2)/24

Angle = 165

Here, we have

The curved surface area of the frustum is approximately 1356.51m². The total surface area of the frustum is approximately 1915.09m². The volume of the frustum is approximately 12348.57m³.

To find the curved surface area of the frustum, we need to find the slant height of the frustum first. Using the Pythagorean theorem, we have

l = √(h² + (R-r)²)

where h = 28m, R = 14m, and r = 6m

l = √(28² + (14-6)²) = √(784 + 64) = √848 ≈ 29.12m

The curved surface area of the frustum can be calculated as

CSA = π(R+r)l

CSA = 22/7 × (14+6) × 29.12

CSA ≈ 1356.51m²

The total surface area of the frustum can be calculated as the sum of the curved surface area and the areas of the top and bottom circles. The area of a circle with radius r can be calculated as πr². Thus, we have

TSA = CSA + πR² + πr²

TSA ≈ 1356.51 + 22/7 × 14² + 22/7 × 6²

TSA ≈ 1915.09m²

The volume of the frustum can be calculated as

V = 1/3 × πh(R² + Rr + r²)

V = 1/3 × 22/7 × 28(14² + 14×6 + 6²)

The 95 percent confidence interval is (0.20, 0.32).

a. We can construct a 95% confidence interval to estimate the percentage of yellow peas as follows:

Let p = proportion of yellow peas = 155/595 = 0.26

Sample size = n = 595

Standard error = SE = √(p × (1-p) / n) = √(0.26 × (1-0.26) / 595) = 0.03

95% confidence interval = p ± 1.96 × SE

Explanation:

A = set of odd numbers = {1,3,5}

B = set of factors of 12 = {1,2,3,4,6}

A U B = union of set A and set B

A U B = {1,3,5} union {1,2,3,4,6}

A U B = {1,3,5,       1,2,3,4,6}

A U B = {1,2,3,4,5,6}

The set union operation combines two sets into one bigger set. Duplicates are tossed out.

There are 6 elements in the set A U B = {1,2,3,4,5,6} out of 6 faces of the number cube.

Therefore, the probability event  A U B happens is 6/6 = 1 = 100%; i.e. it is guaranteed to happen. Each face of the number cube is either odd, a factor of 12, or both.

ANSWER: 8.11

Answer:

We can start by dividing both sides of the equation cos(Ф) + 2sin(Ф) = 0 by sin(Ф):

cos(Ф)/sin(Ф) + 2 = 0

We can then use the identity cot(Ф) = cos(Ф)/sin(Ф) to substitute for cos(Ф)/sin(Ф):

cot(Ф) + 2 = 0

Subtracting 2 from both sides, we get:

cot(Ф) = -2

Therefore, we have shown that cos(Ф) + 2sin(Ф) = 0 can be expressed as cot(Ф) = -2.

Answer: 1226.72g

Step-by-step explanation:

If 460g of flour is needed to make enough dough balls for 6 people, we can find the amount of flour needed for each person by dividing 460 by 6:

460 g / 6 = 76.67 g/person

To find the amount of flour needed for 16 people, we can multiply the amount of flour needed per person by the number of people:

76.67 g/person * 16 people = 1226.72 g

Therefore, we need 1226.72 g of flour to serve 16 people.

A possible coordinate pair for vertex N is (2.42, 2.58).

We have,

The area of the square is 9 square units, and each side of the square must have a length of 3 units.

Let's start by finding the coordinates of vertex P.

Since the square is a square, we know that the x-coordinate of P is the same as the y-coordinate of M, and the y-coordinate of P is the same as the x-coordinate of M.

The coordinates of P are (3, 2).

To find the coordinates of N, we can use the fact that the diagonals of a square bisect each other and are perpendicular.

The midpoint of MP is the same as the midpoint of NQ, and the slope of MP is the negative reciprocal of the slope of NQ.

The midpoint of MP.

= [(2+3)/2, (3+2)/2]

= [2.5, 2.5]

Now,

The slope of MP is (2-3)/(3-2) = -1.

We now have the coordinates of one endpoint of NQ (the midpoint) and its slope.

We can use the point-slope form of the equation of a line to find the equation of NQ:

y - 2.5 = -1(x - 2.5)

y - 2.5 = -x + 2.5

y = -x + 5

We know that N is on the line NQ and that it is a distance of 3 units from the midpoint of NQ, which is (2.5, 2.5).

We can use the distance formula to find the coordinates of N:

d = √((x2 - x1)^2 + (y2 - y1)^2)

3 = √((x - 2.5)^2 + (y - 2.5)^2)

Squaring both sides:

9 = (x - 2.5)² + (y - 2.5)^2

We also know that N is on the line y = -x + 5.

We can substitute this into the equation above to get:

9 = (x - 2.5)^2 + (-x + 2.5 - 2.5)^2

9 = (x - 2.5)^2 + (x - 5)^2

9 = x^2 - 5x + 6.25 + x^2 - 10x + 25

0 = 2x^2 - 15x + 30.75

0 = x^2 - 7.5x + 15.375

We can use the quadratic formula to solve for x:

x = (7.5 ± √(7.5² - 4(1)(15.375))) / (2(1))

x = (7.5 ± √(13.875)) / 2

x ≈ 5.08 or x ≈ 2.42

Since vertex N is to the left of vertex M, we choose the smaller value of x: x ≈ 2.42.

Now we can substitute this value of x into the equation y = -x + 5 to find the corresponding value of y:

y ≈ 2.58

Therefore,

A possible coordinate pair for vertex N is (2.42, 2.58).
