The mean of the population possible using these samples is; C. Yes, the variation of the sample means is small
What is a sample mean?Sample mean is an average of a set of data . And, the sample mean can be used to determine the standard deviation, central tendency, and the variance of a data set.
The sample mean can be applied to various uses, including calculating population averages.
Where, the sample variance is a measure of the degree to which the numbers in a list are spread out. And the numbers given are close to each other;
If the numbers in a list are all close to the expected values; the variance will be small and if they are far away, the variance will be more.
Hence, the correct option is C.

Al sumar su doble, su mitad y 15 se obtiene 99.
Answer:x = numero
2x= doble
x/2= mitad
sumamos todo : x+2x+x/2+15=99
7x/2= 99-15
7x= 84(2)
x=168/7
x=24
comprueba sumando 24+48+12+15=99 suerte!!!
Step-by-step explanation:
The value of the unknown number is 33.6
Let the unknown number be "x"
The half of the number is 0.5x
Double of the number is expressed as 2x
Adding this functions together and 15 and equating to 99 will give;
0.5x + 2x + 15 =99
Solve for x
2.5x = 99 - 15
2.5x = 84
x = 84/2.5
x = 33.6
Hence the value of the unknown number is 33.6

True or False? The blue radius is perpendicular to the green chord.
The statement that the blue radius is perpendicular to the green cord is false
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false

it depends on the number X is.The property tax on a $60,000 home is $1,500. At this rate what will the property tax be on a home worth $75,000?
Answer:
The answer is $1,875
Step-by-step explanation:
1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750
2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000
3. So then $1,500 + $375 = $1,875
4. $75,000:$1,875

David kicks a ball off the ground. After t seconds, it’s height, h (in feet), is given by the formula h=-16t^2+80t. How many seconds does the ball reach its maximum height? What is the maximum height reached by the ball?
Answer:
The ball reaches its maximum height at 2.5 seconds
The maximum height is 100 feet
Step-by-step explanation:
Maximum Value of Functions
We use the derivative of a function to find its maximum or minimum value over a given interval.
Given a function y=f(x), the first derivative criterion establishes if x=a is such that:
f'(a)=0, and f''(a) < 0 then x=a is a maximum of f.
The height h in feet of a ball after t seconds is:
[tex]h(t)=-16t^2+80t[/tex]
Find the first derivative:
[tex]h'(t)=-32t+80[/tex]
Equate to 0:
[tex]-32t+80=0[/tex]
Subtract 80:
[tex]-32t=-80[/tex]
Divide by -32:
[tex]t = -80 / (-32) = 2.5[/tex]
t=2.5 seconds
Find the second derivative:
h''(t)=-32
Since h''(t) is always negative, then
The ball reaches its maximum height at 2.5 seconds
To find the value of the maximum height, substitute t=2.5 into the function:
[tex]h(2.5)=-16(2.5)^2+80*2.5=-100+200 = 100[/tex]
The maximum height is 100 feet
