Answer:

Step-by-step explanation:

if using centimeters to determine the perimeter then it's just cm.

If you're using centimeters to determine area it would be cm^2.

If you're using centimeters to determine volume it would be cm^3.

Using Pythagorean thereon

$\\ \Large\sf\longmapsto P^2=H^2-B^2$

$\\ \Large\sf\longmapsto P^2=9^2-6^2$

$\\ \Large\sf\longmapsto P^2=81-36$

$\\ \Large\sf\longmapsto P^2=45$

$\\ \Large\sf\longmapsto P=\sqrt{45}$

In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushel

Liula [17]

Answer:

Option A is correct.

y = 35.4 bushels per acre when rainfall = 7.1 inches

Step-by-step explanation:

An image of the steps to obtain the equation that relates x to y is attached to this answer.

n = number of variables = 9

μₓ = mean of variable x (rainfall in inches)

μᵧ = mean of variable y (yield in bushels per acre)

σₓ = standard deviation of variable x (rainfall in inches)

σᵧ = standard deviation of variable y (yield in bushels per acre)

y = 4.379x + 4.268

when x = 7.1

y = 4.379(7.1) + 4.268 = 35.3589 = 35.4 bushels per acre.
