For this question the average height of adult women is 63.7” with a sigma of 2.9”. The US Navy requires that fighter pilots have heights of between 62 and 78 inches. Find the approximate percentage or women who qualify to be fighter pilots. HINT: Drawing a distribution curve may help.
Answer:
72%
Step-by-step explanation:
For this question the average height of adult women is 63.7” with a σ of 2.9”. The US Navy requires that fighter pilots have heights of between 62 and 78 inches. Find the approximate percentage or women who qualify to be fighter pilots. HINT: Drawing a distribution curve may help.
Find the z-scores.
z = (x − μ) / σ
z₁ = (62 − 63.7) / 2.9
z₁ = -0.586
z₂ = (78 − 63.7) / 2.9
z₂ = 4.93
Use a chart or calculator to find the probability.
P(-0.586 < Z < 4.93) = P(Z < 4.93) − P(Z < -0.586)
P(-0.586 < Z < 4.93) = 1.000 − 0.279
P(-0.586 < Z < 4.93) = 0.721
Approximately 72% of women will qualify.
If the Navy changes its height requirement to include all but the shortest and tallest 3% of the female population, what would the new height requirements for women be? HINT: Drawing a distribution curve may help. Also, rounding is suggested.
In this case, we work in reverse. Use a chart or calculator to find the z-score for each probability.
P(Z < z₁) = 0.03
z₁ = -1.881
P(Z > z₂) = 0.03
P(Z < z₂) = 0.97
z₂ = 1.881
Now find the heights associated with those z-scores.
z = (x − μ) / σ
-1.881 = (x₁ − 63.7) / 2.9
x₁ = 58.2
1.881 = (x₂ − 63.7) / 2.9
x₂ = 69.2
The new height requirement is between 58.2" and 69.2".

Which set of transformations would prove ΔLMN ~ ΔPQR?
Answer:
B. Dilate ΔPQR by the scale factor of 2 from point Q, and translate ΔP′Q′R′ by the rule (x + 1, y + 0).
Step-by-step explanation:
Dilations make the most sense for the shapes shown, and it can't be A because if you were to do y - 1 then it would be further away and would no longer be equivalent.
Answer:
would actually be answer D. Translate ΔPQR by the rule (x + 1, y − 1), and dilate ΔP′Q′R′ by a scale factor of 2 from point R.

Answer:
Its blurry, can you take another picture?
Step-by-step explanation:
Answer:
1456 square unitsStep-by-step explanation:
The shape can be considered as the combination of a square with the side of 28 and a triangle with base of (28 + 10 + 10) and the height of 28
Then the area of the shape is:
28*28 + 1/2*48*28 = 784 + 672 =1456 square unitsThe function t= 21.55 cos (pi/6(m-7)) + 43.75 models the average high temperature in degrees Fahrenheit each month

need help to determine if it's a undefined slope or it is a slope of line and what's the answer please and thank you
Answer:
It is slope of a line which is 4
Step-by-step explanation:
We are given that the given points are generated by a linear function. A linear function is ta straight line that can be represented by:
[tex]y = mx+b[/tex]
Here m is the slope
The slope of a line is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
In order to find the slope from the table we take any two pairs of inputs and outputs i.e. x and y
So here we take
(x1,y1) = (-6,-16)
(x2,y2) = (-5,-12)
Putting the values in the formula
[tex]m = \frac{-12-(-16)}{-5-(-6)}\\m = \frac{-12+16}{-5+6}\\m = \frac{4}{1}\\m = 4[/tex]
Hence,
It is slope of a line which is 4

Answer:

Step-by-step explanation:
I took the test ;)
Isaac creates a scatter plot showing the association between the height and weight of his male
classmates. He models the association with the equation w = 6.5h - 275, where h is the
classmate's height in inches and w is the classmate's weight in pounds. What is the meaning of the
slope in this equation?
Answer:
Step-by-step explanation:
Given
w is the classmate's weight in pounds
h is the height
The general formula for the expression is y = MX+c where
m is the slope
c is the intercept
M is the change in y to change in x
Comparing with the given equation
w = 6.5h - 275, we will see that the slope of the equation is 6.5 and can be expressed as the change in the classmate's height to the classmate's weight
slope = dh/dw = 6.5

Calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n.
Answer:
The solutions for 1 + 3 + 5 +...+ (2n - 1), for the first 10 natural numbers are given in the explanation section below.
Step-by-step explanation:
To calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n, we will use several natural numbers to represent n.
For n= 1,
2n - 1 = 2(1) - 1 = 2 - 1 = 1
Hence, 1 = 1
For n = 2,
2n - 1 = 2(2) - 1 = 4 - 1 = 3
Hence, 1 + 3 = 4
For n = 3,
2n - 1 = 2(3) - 1 = 6 - 1 = 5
Hence, 1 + 3 + 5 = 9
For n = 4,
2n - 1 = 2(4) - 1 = 8 - 1 = 7
Hence, 1 + 3 + 5 + 7 = 16
For n = 5,
2n - 1 = 2(5) - 1 = 10 - 1 = 9
Hence, 1 + 3 + 5 + 7 + 9 = 25
For n = 6,
2n - 1 = 2(6) - 1 = 12 - 1 = 11
Hence, 1 + 3 + 5 + 7 + 9 + 11 = 36
For n = 7,
2n - 1 = 2(7) - 1 = 14 - 1 = 13
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49
For n = 8,
2n - 1 = 2(8) - 1 = 16 - 1 = 15
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64
For n = 9,
2n - 1 = 2(9) - 1 = 18 - 1 = 17
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 81
For n = 10,
2n - 1 = 2(10) - 1 = 20 - 1 = 19
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100

Select each situation that can represent a proportional relationship.
A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.
B) The total amount of snow that falls in d days when there's already 5 inches of snow on the ground.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
D) The length in x months of a baby that grows 2 inches per month and was born 7 inches long.
Using the concept of proportionality, it is found that these following situations represent proportionality:
A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
In a proportional relationship, the output y is given by the input x multiplied by a constant k, that is:
[tex]y = kx[/tex].
Thus, when x = 0, y = 0.In this problem:
In options A and C, when the input is 0, the output is also 0, thus they are proportional.In option B, when the input is 0 days, the output is 5 inches of snow, thus it is not proportional.In option D, when the input is of 0 months, the height is of 7 inches, thus also not proportional.A similar problem is given at https://brainly.com/question/22846068
