a) The average arithmetic mean is calculated by adding all of the values and then dividing the sum by the total number of values.

\frac{198+199(3)+200(2)+201(5)+202(2)}{13} =200.3

Which is 200.3.

b) Assume that the new average mean is 201, then

201 = \frac{198 + 199(3) + 200(2) + 201(5) + 202(2)+x}{14}

Solve for x.

2814= 2604x

Divide by 2604 to solve for x.

\frac{2814}{1604} = x = 1.75

So the height of the new player is 175 cm.

Use the cubic model y = 5a3 - 2a2 + a - 45 to find the value of y when x = 4.
Naddik [55]

Assuming 5a3 equals 5a^3, and the same for everything else, you would plug in 4 for a, so 5(4)^3 - 2(4)^2 + 4 - 45, which equals 247.

This is a same side interior angle, which means that the two angles, when added, will equal 180°

y + 72 = 180

Isolate the y, subtract 72 from both sides

y + 72 (-72) = 180 (-72)

y = 180 - 72

y = 108

A) 108°, is your answer
