Soloha48 [4]

Answer:

The new height requirements are minimum of 64.1875 inches and maximum of 68.3 inches

Step-by-step explanation:

To exclude the tallest 50% of men and shortest 5% of men, we need to find the critical z-value for a significance level of 0.5 & 0.05 and then solve for x in the z-score equation.

For significance value of 0.5, z = 0

We are given;

μ = 68.3 in

σ = 2.5 in

Thus from z = (x - μ)/σ, we have;

0 =(x - 68. 3)/2.5

0 = x - 68. 3

x = 68.3 inches for men max

Similarly, for significance value of 0.05, z = -1.645

Thus to find x;

-1.645 = (x - 68. 3)/2.5

-4.1125 = x - 68.3

x = 68.3 - 4.1125

x = 64.1875 inches for men min

Three more than five times a number is less than or equal to eight?how do you write that in numbers?
Korolek [52]

3 + 5x ≤ 8 is how this would be displayed in numbers.

To solve, we treat this like an algebraic equation.

Subtract 3 from both sides.

5x ≤ 5

Divide both sides by 5.

x ≤ 1

The value of x is less than or equal to 1 to make the inequality true.
