C. Yes, the variation of the sample means is small.

Step-by-step explanation:

edge

Answer 2

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.

Answers

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.

Answers

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

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?

Answers

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

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?

Answers

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

What would be the slope for a line perpendicular to y = -¼x + 2?

Answers

Answer:

m perpendicular= [tex]-\frac{1}{notlinear}[/tex]

Step-by-step explanation:

So here we have an equation with a negative slope. And it wants us to find the perpendicular slope

So if our slope is negative, the slope perpendicular to that would be the positive reciprocal.

Let m= -A/B so the slope perpendicular to that would be B/A

Here our slope is -1/4 so the slope perpendicular to that would be -(-4/1) which is just 4

Therefore your perpendicular slope would be 4
