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:
b
Step-by-step explanation:
because heat transfer from hot to cold but it does not transfer to something hotter or the same exact temp

Solution:
When you are finding the percent of a number, turn that percent into a decimal and multiply.
~Turn 11% to a decimal
11 / 100 = 0.11
~Multiply
2,720 x 0.11 = 299.2

Answer:
Point A is 
miles far from point B.
Step-by-step explanation:
Draw a diagram by using the given information.
1. Move 8 units up to reach at point Q. (Walk from point A ,8 miles due north).
2. Move 5 units right to reach at point R. (5 miles dues east)
3. Move 4 units down to reach at point B. (4 miles due north to point B)
4. Drawn a line PB as shown below.
From the below figure it is clear that
AP = 8-4 = 4 miles
PB = QR = 5 miles
Using Pythagoras we get
Taking square root on both sides.
Therefore, point A is miles far from point B.
They are both correct! Michael's equation is just a distributed version of Laurie's equation. Laurie's equation is solved like this: First distribute to get
2x + 1.2 + 0.8 + 0.7, then add the numbers together to get 2x + 2.7.
Michael's equation also starts with distributing to get 2x + 1.2 + 0.8 + 0.7 and adding the numbers together to get the same answer: 2x + 2.7. Hope this helps!
