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.
<h3>
is the recursive formula of the geometric sequence</h3>
<em><u>Solution:</u></em>
<em><u>Given geometric sequence is:</u></em>
-0.6, 3 , -15, 75
We have to frame the recursive formula
Find the common ratio
Thus common ratio is -5
<em><u>The nth term of geometric sequence is given as:</u></em>
Where,
n is the nth term
a is the first term of sequence
r is common ratio
From sequence,
a = -0.6
r = -5
Therefore,
Where, n = 1 , 2 , 3 , 4 , .....
Thus the recursive formula is found
