Answer:
Number = 2
Step-by-step explanation:
Let the number be <em>x</em>.
According to the question,
- Number increased by 11 = x+11
- Multiplied by 2 is 26 : (x+11)*2 = 26
Equation will be,
Solving for x,
- 2x+22 = 26
- 2x = 26-22
- 2x = 4
- x = 4/2
- x = 2
Thus,the number is 2.
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
