Answer:
Variance population of 147,141,120,124,128 = 106
Variance sample of 147,141,120,124,128 = 132.5
Hope this helps and PLSSS MARK AS BRAINLIEST :)
The answer is B. 36.
the ratio is 4:2, the number 4 is twice as much as 2. so if there's 18 algebra problems (representing the 2 in the ratio), then there would be twice as many data analysis problems. 18 times 2 equals 36. :) hope it helps!
Hi there!
The formula for the perimeter of a rectangle is P = 2 (l + w).
We can simplify this formula so that we can find the solutions easier.
P = 40
40 = 2 (l + w)
divide both sides by 2
40/2 = l + w
20 = l + w
So the length + width has to equal to 20.
So your answers would be B , C , D.
Hope this helped! :)
Answer:
Yes
Step-by-step explanation:
This represents a linear function because as it increases one in it always goes up 4.
We need the exact value of
to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives
Plug this into either equation and you get
(It's guaranteed that
in this case because that already corresponds to
.)
