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.

Complete the recursive formula of the geometric sequence − 0.6   ,   3   , − 15   ,   75 , . . .
HACTEHA [7]
<h3>a_n = -0.6 \times (-5)^{n - 1} 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

r = \frac{3}{-0.6} = -5\\\\r = \frac{-15}{3} = -5\\\\r = \frac{75}{-15} = -5

Thus common ratio is -5

<em><u>The nth term of geometric sequence is given as:</u></em>

a_n = a \times r^{n-1}

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,

a_n = -0.6 \times (-5)^{n - 1}

Where, n = 1 , 2 , 3 , 4 , .....

Thus the recursive formula is found

Find the missing angle x<br> Then BAC
Liono4ka [1.6K]

Answer:

Step-by-step explanation:

since arc BC is 2 time the angle of A   , then

2(9x +12) = 21x +3

18x +24 = 21x + 3

21 = 3x

7 = x

x = 7

∠BAC = 9(7) +12

∠BAC = 63 +12

∠BAC = 75°
