Answer:
The First one
Step-by-step explanation:
-2 with zero , -1 with zero , zero with 6
etc....
from the diagram you see that.
Answer:
Option B.
Step-by-step explanation:
Given information:
Σ(x − M) = 44
where, M is mean.
Sample size = 12
The computational formula for sample variance is

where, M is sample mean and N is sample size.
Substitute Σ(x − M) = 44 and N=12 in the above formula.



The sample variance is 4.0.
Therefore, the correct option is B.

Answer:
It would cost 47.36
Step-by-step explanation:
First, you need to find out how many gallons are needed to fill the tank. To do this, simply multiply 25 by the fraction that is how much is already in there:
25 x
= 9.375
So that means that there is 9.375 gallons already in the tank. To find the amount needed to fill the tank:
25 - 9.375 = 15.625
So 15.625 gallons are needed, rounded up to 16 gallons because you cannot get a decimal value of gallons.
That means that 16 x the price = the amount to fill the tank:
16 x 2.96 = 47.36
So it would cost 47.36 to fill the tank!
