Answer:
B
Step-by-step explanation:
The screenshot given explains the formula of standard deviation, which measures the variation of numbers in a set.
It basically says we have to find the sum of all the numbers subtracted by the mean squared, and divide that by the number of data sets, and then square root.
The only way we can get this problem is by B.
Answer:
-15 is how many tests per hour i think, and 78 is how many tests total
Step-by-step explanation:
= 78 − 15ℎ
1 hour would be
78-(15x1)=63
2 hours would be
78-(15x2)=48
and so on.
Answer:
y -11 = -2(x+4)
or
y = -2x+3
Step-by-step explanation:
We can use the point slope form of a line
y - y1 = m(x-x1) where m is the slope and (x1 ,y1) is a point on the line
y - 11 = -2(x- -4)
y -11 = -2(x+4)
We can rewrite it in slope intercept form
y-11 = -2x-8
Add 11 to each side
y = -2x+3
