Answer:
5/12, $10
Step-by-step explanation:
Lea earned $24 babysitting. She spent ⅔ of that amount on a gift for her bestie, ¼ on snacks. What fraction of her earning is left? How much money does she have left?
Let the total amount earned be 1
Given
Amount on snacks = ¼
Amount on babysitting = ⅔
Required
Fraction left
Fraction left = Total -(snacks+babysitting)
Fraction left = 1-(1/4+2/3)
Fraction left = 1-(3+4/12)
Fraction left = 1-7/12
Fraction left = 5/12
Amount of money she has left = 5/12 × 24 = 5×2 = $10
Hence she has $10 left

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.

What are the
relationships among angles that are created
when a line intersects two parallel lines?
Answer:
angles
Step-by-step explanation:
trust me
The relationship between the angles created by the intersection of 2 parallel lines are solved
What are Parallel Lines Cut by Transversal?Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
Let the first line be represented as m
Let the second line be represented as n
Now , the lines m and n are parallel lines
And , let the transversal line be t , which intersects m and n
So , Alternate angles are equal
Corresponding angles are equal
Co-interior angles add up to 180°
Hence , the angles formed are solved

S = 6t² + 3t + 7, 0 ≤ t ≤ 2 Find the body's displacement and average velocity for the given time interval. A) 30 m, 30 m/sec B) 44 m, 22 m/s C) 18 m / sec , 27 m /sec D) 30 m / sec , 15 m /sec
Answer:
30m, 24m/s
Step-by-step explanation:
Given the expression for the position of the object expressed as:
S = 6t² + 3t + 7,
At t = 0
S0 = 6(0)²+3(0)+7
S0 = 0+0+7
S(0) = 7m
At t = 2
S2 = 6(2)² + 3(2)+ 7
S2 = 6(4)+6+7
S2 = 24+13
S2 = 37
The displacement = S2-S0 = 37-7= 30m
For the velocity
V = dS/dt = 12t+3
At t = 0
V0 = 12(0)+3
V0 = 3
At t= 2
V2 = 12(2)+3
V2 = 24+3
V2 =27
The velocity will be V2-V0 = 27-3 = 24m/s
Help me, please. It’s due at 8AM.
Answer:
93
Step-by-step explanation:
v=66×62/44=93
hope it helps
Hey there!
“66 / v = 44 / 62”
~ FIRST you have to CROSS MULTIPLY
66 • 62 = 44 • v
66 • 62 = 4,092
44 • v = 44v
➡️ 4,092 = 44v
~ SECOND TURN/FLIP your EQUATION
44v = 4,092
~ THIRD DIVIDE both SIDES by 44
44v / 44 = 4,092 / 44
CANCEL out: 44 / 44 because that gives you 1
KEEP: 4,092 / 44 because that gives you the v-value
FOURTH: SOLVING
4,092 / 44 = v ; v = 4,092 / 44
Solve the equation that’s in STEP FOUR and you have your v-value
Answer:
v = 93 ☑️

Beatriz takes a simple random sample of 350350350 orders from the more than 500050005000 total orders to her store and finds that 12\, percent of the sampled orders were returned. Assuming that it is really 9\%9%9, percent of all orders to her store which were returned, what is the approximate probability that more than 12\, percent of the sampled orders would have been returned
If Beatriz takes a simple random sample of 350 orders from the more than 5000 total to her store and finds. The probability that more than 12 percent of the sampled orders would have been returned is 0.02.
How to find the probability?Mean = n * p
Mean = 350 * 0.09
Mean= 31.5
Standard deviation = √ p * (1 - p)/n
Standard deviation = √ 0.09 * 0.91/350
Standard deviation = 0.01529
Using the normal distribution table
p>0.12
P(p>0.12) =0.02
Therefore the probability that more than 12 percent of the sampled orders would have been returned is 0.02.

The amount of gasoline at a gas station changes from 58,432.4 gal to 56,475.2 gal from 2:00 PM to 4/0 PM . What rational number represents the average change in amount of gasoline per hour ?
-1957.2
1957.2
-978.6
978.6
Answer:
- 978.6 gallons per hour
Step-by-step explanation:
Given that :
Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal
Time during which change occurred : 2:00 pm to 4:00 pm
Average change per hour : [Change in gallon of gasoline / time interval (hour)]
Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons
Time interval = 4:00 pm - 2:00 pm = 2 hours
Hence, Average change per hour :
-1957.2 / 2
= - 978.6 gallons per hour
