Answer:

Option E) 61.6

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100 bushels per acre

Standard Deviation, σ = 30 bushels per acre

We assume that the distribution of yield is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X>x) = 0.90

We have to find the value of x such that the probability is 0.90

P(X > x)

$P( X > x) = P( z > \displaystyle\frac{x - 100}{30})=0.90$

$= 1 -P( z \leq \displaystyle\frac{x - 100}{30})=0.90$

$=P( z \leq \displaystyle\frac{x - 100}{30})=0.10$

Calculation the value from standard normal table, we have,

$P(z$

$\displaystyle\frac{x - 100}{30} = -1.282\\x = 61.55 \approx 61.6$

Hence, the yield of 61.6 bushels per acre or more would save the seed.

Find the missing values.

Gnom [1K]

5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

$\frac{40}{60}$ = $\frac{x+12}{42}$

$\frac{2}{3}$ = $\frac{x+12}{42}$

3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16

Angle H = 180 - 52 - 36 = 92
