Two random samples were taken to determine how often people in a community listen to the local radio station each month.
The first sample surveyed 15 people as they exited the bank on Main Street. The first sample found that the mean number of hours they listened to the radio each month was 20.
The second sample surveyed every sixth person as they exited the only local grocery store until 100 people were surveyed. The second sample found that the mean number of hours they listened to the radio each month was 12.
Which statements are true? Check all that apply.
The second sample is random.
The second sample is likely to be more representative of the population.
The first sample is likely to be more representative of the population.
The second sample will give a better representation because is it larger.
The first sample will give a better representation because it is smaller.
Community members are more likely to listen to the radio station an average of 12 hours a month than 20 hours a month.

If the length of the longer leg in a 30°-60°-90° triangle is 5V3, what is the length of the shorter leg?
A. 3
B. 5
C. 5v2
D. 10
Answer:
B. 5
Step-by-step explanation:
Let x = length of shorter leg
longer leg = [tex]\sqrt{3}[/tex] times the shorter leg
5[tex]\sqrt{3}[/tex] = x[tex]\sqrt{3}[/tex]
x = 5
A pediatrician records the age (in months) and the height (in inches) of a baby over time and creates a scatter plot. Using the scatter plot, the pediatrician determines that the model that can be used to predict the baby's height is y=1.3x+18, where y is the height of the baby and x is the age of the baby. What does the 18 in the equation tell us? Need help plz i will make you the brilliants
A
The baby grows 1.8 inches per year.
B
The baby weighs 18 pounds when born.
C
The baby was 18 inches when born.
D
The baby grows 18 inches per year.
Answer:
Your answer would be C
Step-by-step explanation:
18 inches was the height of the baby when they were born since it isn't y which would be the current height of the baby now in months that tells me months have passed which includes x is the age of the baby in months.

The function y = -16x2 + 1500 gives a parachute jumper's height y in feet
after "X" seconds for a jump from 1500 feet. How long is free fall if the
parachute opens at 1100 feet?
Answer:
Step-by-step explanation:
so the question is asking about the time from 1500 feet to 1100 feet. How long did they fall, w/o a parachute. aka "freefall" so, at 1500 feet the jumper is really at time zero. so, plug in to the formula
1100 = -16[tex]x^{2}[/tex] +1500
( x represents seconds so i'll change it to t so we know it's time )
1100 = -16[tex]t^{2}[/tex] + 1500
now we can solve for t , to see how long the jumper falls
-400 = - 16[tex]t^{2}[/tex] ( subtracting 1500 from both sides of equation )
25 = [tex]t^{2}[/tex] ( dividing both sides by -16 )
oh.. look at how nice that turns out.. :)
[tex]\sqrt{25}[/tex] = t ( take the square root on both sides )
5 = t
the jumper fell for 5 seconds to get to 1100 feet

Hey there!
2(12)3/2
= 2(12)(3/2)
= 24(3/2)
= 24/1 * 3/2
= 24(3) / 1(2)
= 24 + 24 + 24 / 1 + 1
= 48 + 24 / 2
= 72 / 2
= 72 ÷ 2 / 2 ÷ 2
= 36 / 1
= 36 ÷ 1
= 36
Therefore, your answer is: 36
Good luck on your assignment & enjoy your day!

The graphs below have the same shape. What is the equation of the blue
graph?
g(x) = ?

Answer: it’s c
Step-by-step explanation:
Just took it and it’s correct
The equation of graph of the transformed function is g ( x ) = ( x + 4 )² - 3
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) = x²
Let the second function be g ( x )
Now , the vertex of the function is at A ( -4 , -3 )
When the function is shifted left by 4 units and down by 3 units , we get
g ( x ) = ( x + 4 )² - 3
Hence , the transformed function is g ( x ) = ( x + 4 )² - 3 and the graph is plotted

Place the correct symbol in the space provided: 1/2 ___ 3/8
>
<
=
Answer:
1/2 > 3/8
Step-by-step explanation:
To compare the answers, we need to change them to the same denominator.
2x4=8
So we can create an equivent fraction of 1/2 by dividing both numbers by 4:
1x4=4
2x4=8
1/4=4/8
Now we are comparing 4/8 and 3/8, and we can see clearly that 4/8 is greater than 3/8 because 4 is greater than 3.
