Answer:
12 boxes
Step-by-step explanation:
because each box has 3.25 so 12 times 3.25 equals 39
It is
(3-x)^2
i made sure it correct this time
Judging by the question I figured the equation you would want to use is 20-31.
If solved the solution would be -11 degrees by the end of the day.
Hope this helped!
Answer:
B
Step-by-step explanation:
You can surely do this! First, find the mean of the 8 given scores. Add up these scores and then divide the result (sum) by 8 to obtain the mean.
raw score - mean
The formula for "z-score" is z = -------------------------
std. deviation
You'll need to calculate the standard deviation of these 8 scores.
73 - mean
Then, as an example: raw score 73 translates into z-score z = ---------------
std. dev.
