Heights of American adult women are normally distributed with mean 63.6 inches and standard deviation 2.5 inches. Find the height of an adult woman that corresponds to the 80th percentile.
Answers
Answer:
65.7
Step-by-step explanation:
Given ;
Mean, m = 63.6
Standard deviation, s = 2.5
80th percentile = 80 / 100 = 0.8
The Zscore corresponding to the 80th percentile ; Z < P = 0.842 (Z probability calculator)
Zscore = (x - m) / s
0.842 = (x - 63.6) / 2.5
0.842 * 2.5 = x - 63.6
2.105 = x - 63.6
x = 63.6 + 2.105
x = 65.705

The answer to this question is 9cm^2, the second answer
Step-by-step explanation:
To find the area of this parallelogram, you have to first find the area of one of the two triangles shown. The formula to solve a triangle is (base * height)/2, so that would be 4.5cm^2 for each triangle, times two for two triangles would be 9cm^2. If you wanted to do it an easier way, just multiply the length of the bottom of the parallelogram with the height. The measures telling you 3.5 are telling you the length of the diagonal line, so don't pay attention to that.

2. c. $0.08 per square inch
3. f. $10
4. m. $8
5. h. 79 in²
6. j. 113 in²
Step-by-step explanation:
1. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 78.53981
$8.00/25π = $0.10 per square inch
2. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113.0973355
$10.00/36π = 0.088419 = $0.08 per square inch
3. information/answer was provided
4. information/answer was provided
5. A = πr²

r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113 in²

X-11 = 8
Answers
First, you have to get x alone by getting rid of the terms next to it. In this case, it’s -11.
To get rid of a term, do the opposite.
So x - 11 + 11 = 8 + 11
Remember to do it on both sides.
x = 19
Why?
You have to get x alone so you have to add 11 to both sides
X-11+11= 8+11
The 11 cancel out on the left and 8+11 equals 19 so x=19

can someone check behind me if both of these graphs have a slope of 3?
Answers
Answer:
No. The slope of Line E is 3/2, and the slope of Line D is 6/8.
Step-by-step explanation:
For line E, let's find two points that the lines go through: (0,4) and (30, 24).
m=30-0/24-4
m=30/20
m= 3/2 or 1.5
Line E does not have a slope of 3.
Line D goes through these two points: (8,9) and (16,15).
m=15-9/16-8
m=6/8 or 0.75
Line D doesn't have a slope of 3.

Please help! What are the independent and dependent variables of this problem?
Answers
Answers:
Independent Variable = time = tDependent Variable = height = h(t)======================================================
Explanation:
The horizontal axis always represents the independent variable. Often it is x, but in this case, it's t. The time value does not depend on the height. Time does it's own thing.
The height depends on the time value. The vertical axis, or y axis, is always representing the dependent variable. The notation h(t) helps us see that h must be paired with t, in order to find the value of h so to speak. As the time value changes, so does the height of the ball.

Factor 16a + 72 to identify the equivalent expression
Answers
Hey there, thanks for posting your first question!
If you're asked to factor a polynomial, you need to look for the
greatest common factor between the terms that are involved.
The greatest common factor of 16a and 72 is 8 because 8
is the largest number that can divide into both 16 and 72.
The "a" doesn't qualify because it doesn't appear in every term.
So the 8 factors out.
When that happens, we are left with each term divided by that 8
inside a set of parenthses, I'll show you what I mean.
So we have 8(2a + 9).
I divided the 16a by the 8 and 72 by the 8 and if you
distribute it back you will end up with the original polynomial.
So our answer 8(2a + 9).
