martha put $4.87 in her coin bank each day she added in quarter 1 nickel and 3 pennies how much money was in her coin bank after

andrey2020 [161]

Hey You!

1 quarter = 25 cents

25 × 6 = 150

1 nickel = 5 cents.

5 × 6 = 30

3 pennies = 3 cents.

3 × 6 = 18

Add them all up:

4.87 + 1.50 + 0.30 + 0.18 = 6.85

There were $6.85 in the coin bank after 6 days.

The mean of a set of data is -3.82 and its standard deviation is 2.31. Find the z score for a value of 3.99.

gtnhenbr [62]

Answer:

The z- score for a value of 3.99 will be 3.38.

Step-by-step explanation:

It is given that the mean of a set of data is -3.82 and its standard deviation is 2.31.

Thus, the value of the z-score= $\frac{value-mean}{standarddeviation}$

= $\frac{3.99-(-3.82)}{2.31}$

= $\frac{3.99+3.82}{2.31}$

= $\frac{7.81}{2.31}$

= $3.38$

Thus, the z- score for a value of 3.99 will be 3.38.
