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.
Answer:
9a-65
Step-by-step explanation:
simply write 9a+(add the remaining numbers all together)
Answer:
D. (2 , 0)
Step-by-step explanation:
f(x) + d --> (x , y) -> (x , y+d)
(2 , -3) -> (2 , -3+3) -> (2 , 0)
Y=2x+2
(y=mx+c
m-slope/gradient
c-y intercept)
