It’s D

the reason why is because the multiplier must be between 1 and 10
(
1
≤
x
≤
10
)
so first more your decimal there which you get:
2.34
then just count how many numbers the decimal jumped, if the decimal moved left the exponent is positive and if it moved right, as in your number, the exponent is negative

yours moved 3

A farmer is tracking the amount of wheat his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 75 models

mr_godi [17]

Answer:

Average rate of change: 0

Interpretation: No increment in yield from year 5 to year 15.

Step-by-step explanation:

The function that models the yield is:

$f(x)=-x^2+20x+75$

$f(15)=-(15)^2+20(15)+75=150$

$f(5)=-(5)^2+20(5)+75=150$

The average rate of change of f(x) from x=a to x=b is given by the formula;

$AOC=\frac{f(b)-f(a)}{b-a}$

The average rate of change from year 5 to year 15 is:

$\frac{f(15)-f(5)}{15-5}$

$\frac{150-150}{15-5}$

$\frac{0}{10}=0$

Interpretation: There has not been any increment in yield from year 5 to year 15.

A company makes electric motors. The probability an electric motor is defective is 4%. What is the probability that a sample of

MrRissso [65]

Answer:

$P(X = 2) = 0.2613$

Step-by-step explanation:

Given

$p = 4\%$ --- proportion

$x = 2$ --- defective motors

$n = 60$ --- sample size

Required

Determine the probability that exactly 2 is defective

This follows a Poisson distribution and will be solved using:

$P(X = x) = \frac{e^{-u} u^x}{x!}$

Where

u = Expected number of occurrence, and it is calculated as:

$u = np$

$u = 60 * 4\%$

$u = 60 * 0.04$

$u = 2.4$

So:

$P(X = x) = \frac{e^{-u} u^x}{x!}$ becomes

$P(X = 2) = \frac{e^{-2.4}2.4^{2}}{2!}$

$P(X = 2) = \frac{e^{-2.4}* 5.76}{2}$

$P(X = 2) = e^{-2.4}* 2.88$

$P(X = 2) = 0.09071795328* 2.88$

$P(X = 2) = 0.26126770544$

$P(X = 2) = 0.2613$

<em>Hence, the probability that exactly 2 out of 60 will be defective is 0.2613</em>
