Answer:

Amy

Explanation:

Because add all of the numbers and divide by 7.

The measure of center I would use for Amy is 6 because it is higher than half of the numbers and lower than half of the numbers.What I would use for Chelsea is 7 because of the same reason.

Amy:
8 + 5 + 6 + 11 + 4 + 6 +8 = 48
48 divide by 7 = 6.85

chelsea:
7 + 9 + 5 + 3 + 10 + 5 + 8 = 47
47 divide by 7 = 6.71

amy runs more on average.

both mean !

The screen at Dallas' AT&T Stadium is 175 feet wide. A movie theatre screen with

Mazyrski [523]

Answer:

17150 ft²

Step-by-step explanation:

Given the ratio of sides = a : b , then

ratio of areas = a² : b²

Here ratio of sides = 175 : 40 = 35 : 8 , then

ratio of areas = 35² : 8² = 1225 : 64

let x be the area of AT & T Stadium then by proportion

$\frac{x}{1225}$ = $\frac{896}{64}$ ( cross- multiply )

64x = 896 × 1225 = 1097600 ( divide both sides by 64 )

x = 17150

The AT & T screen has an area of 17150 ft²

In a triangle, the sum of the measures of the first two angles is 12 less than the measure of the third angle. In addition, the

<h3>What is a Triangle ?</h3>

A triangle is a polygon with three sides , three vertices an three angles.

It is given to make system of equations

Let the measure of the first , second and third angle be x, y and z

the sum of the measures of the first two angles is 12 less than the measure of the third angle.

x +y = z -12 ----1

the measure of the first angle is twice as big as the measure of the second angle.

x = 2y

Now equation 1 will be

z - 3y = 12

x +y+z = 180

2y +y +z = 180

3y +z = 180 ----2

z - 3y = 12------3

On solving the system of equation 1, 2

2z = 192

z= 96 degree

3y = 180-96

y = 28

x = 56

Therefore the measure of the three angles area 56, 28 , 192 degree.
