Answer: z = -19.5
Step-by-step explanation:
-6.5 = z/3
-19.5 = z Multiply 3 to both sides
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
Answer:
Step-by-step explanation:
14000 after 5 years
Answer:
3f - 2f = 6 + 23( collection of like terms)
f = 29
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.
