On average, it takes a shoe factory 21 minutes, with a standard deviation of 3 minutes, to manufacture a pair of running shoes.

algol13

Answer:

The number of times it would take more than 27 minutes to manufacture a pair of running shoes is 2.275 times or approximately 2 times per every 100 shoes

Step-by-step explanation:

The average time it takes to manufacture a pair of shoes = 21 minutes;

The standard deviation = 3 minutes

To find how often it takes more than 27 minutes to manufacture a pair of running shoes, we have;

Standard score, given as follows;

$Z=\dfrac{x-\mu }{\sigma }$

Where;

x = The raw score = 27 minutes

μ = The average score = 21 minutes

σ = The standard deviation = 3 minutes

From which we have;

$Z=\dfrac{27-21 }{3 } = 2$

Therefore, it is borderline unusual with a p value of P(z>2) = 1 - 0.97725 = 0.02275

Therefore, the number of times out of 100 that it would take more than 27 minutes to manufacture a pair of running shoes = 100 × 0.02275 = 2.275 times which is approximately 2 times in every 100 shoes.

How to do the problem

Veronika [31]

Ill work it out w/ the steps so you can do it later on. STEP 1) multiply 95 by .10 to get 9.5 STEP 2) subtract 9.5 from 95 to get 85.5, your new price STEP 3) multiply 85.5 by 1.045 *mini step to get 1.045: add 4.5 to 100, get 104.5, divide by 100, get 1.045* then you get $89.35

When a number is increased by 9 it is five times its opposite. Find the number.

Alla [95]

Let the unknown number be $x$ .

Then the opposite of this unknown number will be $-x$ .

It is given to us in the question that when this unknown number, $x$ is increased by 9, or in other words when 9 is added to this unknown number, $x$ , then this becomes 5 times it's opposite, which is $-x$ .

Thus, from the given condition in the question, the equation we get is as:

$x+9=-5x$
