Answer:

Statistic

Step-by-step explanation:

-In statistics, a statistic is a characteristic or an attribute of a sample used to estimate or calculate the true values/characteristics of an entire population.

-The value 9.6 is only representative of the small sample size of 104 children.

-If the sample size is sufficient enough it can be used to calculate the population's mean, standard deviation and other Central Limit Theorem measures.

M=-2 (-3,4) how do you write it into slope intercept
Blizzard [7]

Answer:

y = -2x - 2

Plug the x- and y-values into the appropriate spaces in the slope-intercept form and see which value for b would make the equation true:

4 = -2(-3) +/- ?

4 = 6 - 2

4 = 4

I don't know if this makes sense, I'm sorry if it doesn't but the answer is correct because it goes through the point (-3,4)

Given f(x) = 6x^4 – 10x^3 + 40x – 50, find f(2)
ASHA 777 [7]
F(x)=6x^4-10x^3+40x-50, plug 2 in for x
f(2)=6(2)^4-10(3)^3+40(2)-50
f(2)=12^4-30^3+80-50
f(2)=20735-27,000+80-50
f(2)=-6,235

How to solve y-b/x=m for y
Slav-nsk [51]
To solve for m we want to get m by itself on one side of the equals sign, with everything else on the other side. First we subtract b from both sides, to get it out of the right side of the equation:
y - b = mx + b - b
y - b = mx
Now we divide both sides by x, to get m completely by itself:
(y-b)/x = (mx)/x
(y-b)/x = m
So m is equal to (y-b)/x.

What is the value of x in the equation 1/5 x-2/3y = 30, when y = 15?
Svetllana [295]

Answer:

The value of x is 200 in the equation 1/5x - 2/3y = 30, when y = 15

Step-by-step explanation:

<u>Given</u>

equation: x - 2/3y = 30

when y = 15

<em>Plug in y:</em>

1/5x - 2/3(15) = 30

1/5x - 10 = 30

<em>add</em> 10 to both sides,

1/5x - 10 + 10 = 30 + 10

1/5x = 40

<em>multiply</em> both sides by 5

1/5x * 5= 40 * 5

x = 200
