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.

Lina20 [59]

Ok let me start it from here.

you are studying about properties of natural numbers or whole number or may be integers.

So , In this  Question you have to follow property of addition of integers.

⇒7+3=( You are at the point 7 on the number line or on the tight rope , you are moving (+3) on the right direction.) So you will reach at 7+1+1+1=10

⇒4+2=( You are at the point 4 on the number line or on the tight rope , you are moving (+2) on the right direction.) So you will reach at 4+1+1=6

In first case Cecil has taken total walk of 10 units and in second case Cecil has taken a walk of 10 units.

Illusion [34]

Answer:

25%

Step-by-step explanation:

The average cost of the automobile in 2013 is $16,000

The present cost now is $20,000

Therefore the rate of increase between the two automobiles can be calculated as follows

= 20,000-16,000/16,000

= 4,000/16,000

= 0.25×100

= 25%

Hence the rate of increase is 25%
