14 On average, it takes a shoe factory 21 minutes, with a standard deviation of 3 minutes, to manufacture a pair of running
shoes. How often will it take the factory more than 27 minutes to manufacture a pair of running shoes?
Note: Assume that a Normal model is appropriate for the distribution of manufacturing times,
A. It takes the factory more than 27 minutes to manufacture a pair of running shoes about 47.5% of the time,
B. It takes the factory more than 27 minutes to manufacture a pair of running shoes about 2.5% of the time,
C. It takes the factory more than 27 minutes to manufacture a pair of running shoes about 95% of the time,
D. It takes the factory more than 27 minutes to manufacture a pair of running shoes about 5% of the time.

answer: 59

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
