Suppose the scores of seven members of a women’s golf team are 68, 62, 60, 64, 70, 66, and 72. Find the mean, median, and midran

Ksenya-84 [330]

The mean, median, and midrange of the given that are 66, 66 and 66 respectively.

Option D) Mean = 66, median = 66, midrange = 66 is the correct answer.

<h3>What is the mean, median, and midrange?</h3>

Mean is the sum total of the number divided by number of terms

Median is the middle number when arranged in ascending or descending order.

Midrange is the average of the sum of the maximum number and the minimum number.

Given that;

Data set: 68, 62, 60, 64, 70, 66, and 72

n = 7

First, we arrange in ascending order.

60, 62. 64, 66, 68, 70, 72

Mean = ( 60 + 62 + 64 + 66 + 68 + 70 + 72 ) / 7

Mean = 462 / 7

Mean = 66

Median = 66

66 is the middle number.

Range = ( Max + Min ) / 2

Range = ( 72 + 60 ) / 2

Range = 132 / 2

Range = 66

Therefore, the mean, median, and midrange of the given that are 66, 66 and 66 respectively.

Option D) Mean = 66, median = 66, midrange = 66 is the correct answer.

For the points in the parabola, we have:

A = (1, 0)
B = (3, 0)
P = (0, 3)
Q = (2, -1).

<h3>How to identify the points on the parabola?</h3>

Here we have the quadratic equation:

y = (x - 1)*(x - 3)

First, we want the coordinates of A and B, which are the two zeros of the parabola.

Because it is already factorized, we know that the zeros are at x = 1 and x = 3, so the coordinates of A and B are:

A = (1, 0)

B = (3, 0).

Then point P is the y-intercept, to get it, we need to evaluate in x = 0.

y = (0 - 1)*(0 - 3) = (-1)*(-3) = 3

Then we have:

P = (0, 3)

Finally, point Q is the vertex. The x-value of the vertex is in the middle between the two zeros, so the vertex is at x = 2.

And the y-value of the vertex is:

y = (2 - 1)*(2 - 3) = 1*(-1) = -1

So we have:

Q = (2, -1).

A pie company arranges its three-flavor cheesecake sampler into equal-sized slices as shown, where S represents strawberry, C re

Citrus2011 [14]

Answer:

$37.68$ square inches

Step-by-step explanation:

Given:

A pie company arranges its three-flavor cheesecake sampler into equal-sized slices: S represents strawberry, C represents chocolate, and P represents plain.

Diameter of the pie = 12 inches

To find: total area of the strawberry portion in the pie

Solution:

Diameter of the pie = 12 inches

Radius of the pie (r) = Diameter / 2 = $\frac{12}{2}=6$ inches

Area of the pie = $\pi r^2=3.14(6)^2=113.04$ square inches

Ratio of the strawberry portion in the pie = $\frac{2}{6}=\frac{1}{3}$

Therefore,

total area of the strawberry portion in the pie = $\frac{1}{3}(113.04)=37.68$ square inches
