Answer:
522
Step-by-step explanation:
516 divided by 9 is 57.34
she would need 522 pennies and she would end up with 9 stacks of 58 pennies
3. The answer is 18 because 12➗4= 3 so 6*3=18
The answer is 66 kilometers.
Start with the given expression: 12g where 'g' standts for the liters of gasoline.
Input your data and solve: 12 * 5.5 = 66

Answer:
2
Step-by-step explanation:
We have
n = 4 scores
SS = 48
For this question, we are required to find the estimated standard error
To get this, we first solve for the variance
S² = SS/n-1
= 48/4-1
= 48/3
= 16
Then S² = 16
S = √16
S = 4
Then the estimated standard error is given by:
S/√n
= 4/√4
= 4/2
= 2.
The estimated standard error is 2.
