Answer:

$\boxed {\boxed {\sf z=2.2}}$

Step-by-step explanation:

The z-score tells us how many standard deviations a value is away from the mean.

The formula is:

$z=\frac{x- \overline{x}}{s}$

where x is the value, $\overline {x}$ is the mean, and s is the standard deviation.

We want to find the z-score for the score of an 83, the mean is 72, and the standard deviation is 5.

$x=83 \\\overline {x}= 72 \\s=5$

Substitute the values into the formula.

$z=\frac{83-72}{5}$

Solve the numerator.

$z=\frac{11}{5}$

Divide.

$z=2.2$

The z-score is 2.2, which means the score of 83 is 2.2 standard deviations above the mean.

AysviL [449]

Answer:

9 hours

Step-by-step explanation:

Let :

Landon hours = x

Ben hours = y

x + y = 14 - - (1)

60x + 56y = 820 - - - (2)

From (1)

y = 14 - x

60x + 56(14 - x) = 820

60x + 784 - 56x = 820

4x = 820 - 784

4x = 36

x = 36/4

x = 9

Landon drove for 9 hours
