The air force reports that the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches. Part A: A male pilot whose height is 74.2 inches is at what percentile? Mathematically explain your reasoning and justify your work. (5 points) Part B: Air force fighter jets can accommodate heights of soldiers between 70 inches and 78 inches without compromising safety. Anyone with a height outside that interval cannot fly the fighter jets. Describe what this interval looks like if displayed visually. What percent of male pilots are unable to fly according to this standard? Show your work and mathematically justify your reasoning. (5 points)
Answer:
Step-by-step explanation:
Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Height of male pilot = 74.2 inches
We have to find the percentile
X = 74.2
Corresponding Z score = 74.2-72.6 = 1.6
P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%
i.e. only 5% are below him in height.
Thus the malepilot is in 5th percentile.
1) A hot tub holds 500 gallons of water and drains at a rate of 10 gallons per minute. Type an equation that represents how many gallons are left in the tub after it has drained for x minutes.
2) After 16.5 min, how much water is left in the tub?
3) How long will it take the hot tub to be completely empty?
Answer:
Step-by-step explanation:
`) y=500-10x
y is how much water is left in the tub
the 500 is how many gallons of water is already in the tub
-10x is how much water is drained every minute
2) plug in 16.5
y=500-10*16.5
y=500-165
y=335
335 gallons left
3) make y 0 because that represents how many gallons are in the tub
0=500-10x
-500=-10x
/-10
x=50
50 minutes

It takes April 7 3/8 to get to her grandparents house so far she has driven 3 5/6 hours what is the best estimate of how much longer she has driven
Answer:
Time remain = 85/24 hours
Step-by-step explanation:
Given:
Total time taken by April = [tex]7\frac{3}{8}[/tex] hours
Time she already drive = [tex]3\frac{5}{6}[/tex] hours
Find:
Time remain
Computation:
Time remain = Total time taken by April - Time she already drive
Time remain = [tex]7\frac{3}{8}[/tex] hours - [tex]3\frac{5}{6}[/tex] hours
Time remain = 85/24 hours

solve 10x-10g(4x-2)=1
Answer:
Below
Step-by-step explanation:
x=[tex]\frac{1-20g}{10(1-4g)}[/tex]
Answer:
using BODMAS=(4x-2)=(2x)
10x-10g(2x)=
10x=10+(2x)=
10x=20x
divide both sides by 10
10x/10=20x/10
x=20/10

yooo my ban is up!!!! 5+37=4-3x
Answer:
x = -38/3
Step-by-step explanation:
lol
Simplify 5 + 37 = 42
42 = 4 - 3x
Subtract 4 from both sides
42 - 4 = -3x
Simplify 42 - 4 = 38
38 = -3x
-38/3 = x

There were 1 200 people in a
village. If 40% of them were adults.
how many children were there?
A. 480
B. 720
C.800
D 1 160
Answer:
A. 480
Step-by-step explanation:
ok so first you multiply 1200 by 40 percent
we gonna change 40 percent to a decimal which will be 0.40
then multiply which will get 480
Answer:
720 children
Step-by-step explanation:
40% were adults
So 60% were children
60% of 1200 is 720 children (0.60 x 1200)
find the value of y when x equals -1.
8x - 2y =10
Answer:
y = - 9
Step-by-step explanation:
Substitute in -1 for x
8(-1) - 2y = 10
-8 - 2y = 10
Subtract -8 from both sides
-8 - (-8) cancels out to 0
10 - (-8) = 18
We are left with:
-2y = 18
Divide by -2 on both sides.
-2y/-2 = y
18/-2 = -9
y = -9
Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag,the skirt cost $16,how much money did kate have at first?
Answer:
$18.28
Step-by-step explanation:
Step one:
given data
Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag
let the total money be x
so mathematically
x-1/8*x= 16
solve for x
x-x/8= 16
8x-x/8= 16
7x/8=16
cross multiply
7x= 8*16
7x=128
divide both sides by 7
x=128/7
x=$18.28

The courtyard of an apartment complex is represented by the vertices T(4, 1), U(30, 11), and V(17, 36). Each unit represents 1 meter. A bench is located at the centroid of the courtyard. Which ordered pair gives the coordinates of the centroid?
Answer:
[tex](x,y) = (17,16)[/tex]
Step-by-step explanation:
Given
[tex]T(x_1,y_1) = (4, 1)[/tex]
[tex]U(x_2,y_2) = (30, 11)[/tex]
[tex]V(x_3,y_3) = (17, 36)[/tex]
Required
Determine the coordinates of the centroid
The coordinate is calculated as:
[tex](x,y) = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3))[/tex]
Substitute values for x's and y's
[tex](x,y) = (\frac{1}{3}(4+30+17),\frac{1}{3}(1+11+36))[/tex]
[tex](x,y) = (\frac{1}{3}(51),\frac{1}{3}(48))[/tex]
[tex](x,y) = (\frac{51}{3},\frac{48}{3})[/tex]
[tex](x,y) = (17,16)[/tex]
Hence, the coordinates of the centroid is (17,16)
3. Let's tell and write the answers as quickly as possible

a) If x = 2y, then x + y
In terms of y
2y + y
3y
b) If x = 3y, then 2xy
In terms of y
2(3y)(y)

2/5 + m = 5/6 Im stuck on that please help.
Answer:
m = 13/30
Step-by-step explanation:
2/5 + m = 5/6
m + 2/5 = 5/6
m + 2/5 - 2/5 = 5/6 - 2/5
m = 13/30
Answer:
M = 13/30
Step-by-step explanation:
2/5 + m = 5/6
Subtract 2/5 from both sides
m = 13/30

THANKS!!! will give brainlyist btw
Answer:
w=5
Step-by-step explanation:
Solve for W by getting it by itself.
1. Divide both sides by -4.
(w + 1)= -24/-4
2. Simplify
(w + 1)= 6
3. Subtract 1 from both sides.
w= 6-1
w= 5
5. Decide whether each equation is true for all, one, or no values of x.
a. 2x + 8 = -3.5x + 19
