Oksanka [162]

Answer:

For every 1000 pairs sold, the manufacturer expect to replace 239 pairs for free.

Step-by-step explanation:

Given:

Mean (μ) = 2.2, Standard deviation(S.D) (σ) = 1.7 years and x = 1 (1 year)

Let's find the Z score.

Z = \frac{x - mean}{S.D}

Now plug in the given values in the above formula, we get

Z = \frac{1 - 2.2}{1.7} = -0.71

Now we have to use the z-score table.

The z-score for 0.71 is 0.2611

Since it z is negative, so we subtract 0.2611 from 0.5000

0.5000 - 0.2611 = 0.2389

Percentage = 0.2389 × 100 = 23.89%

To find replaces for 1000 pairs, we need to multiply 23.89% by 1000

= \frac{23.89}{100} .1000 = 238.9

= 239

The cannot be in decimal, when we round off to the nearest whole, we get

239

natta225 [31]

Answer:  54

<u>Step-by-step explanation:</u>

replace "a" with "-2" in the g-equation

g(a) = a² - 4a + 42

g(-2) = (-2)² - 4(-2) + 42

        =  4       + 8   + 42

        =  54
