A runner runs 8 miles in 92 minutes what is the runner’s unit rate?

nikitadnepr [17]

Answer:

The runner's unit rate is 0.09 miles/minute.

Step-by-step explanation:

Given:

Distance cover by runner = 8 miles and the time taken = 92 minutes.

Now, to calculate the runner's unit rate.

We put the formula to get the unit rate:

Velocity = distance/time

$v=\frac{d}{t}$

$v=\frac{8}{92}$

$v=0.0869$

v = 0.09 miles/minute (approximately)

Therefore, the runner's unit rate is 0.09 miles/minute.

A company gives each worker a cash bonus every Friday, randomly giving a worker an amount with these probabilities: $10 - 0.75,

Shkiper50 [21]

The worker's expected weekly bonus is $30.0

<h3>How to determine the worker's expected weekly bonus?</h3>

The amounts and the probabilities are given as:

x $10 $50

P(x) 0.75 0.25

The worker's expected weekly bonus is calculated as:

$E(x) = \sum x * P(x)$

So, we have:

E(x) = $10 * 0.75 + $50 * 0.25

Evaluate the product

E(x) = $17.5 + $12.5

Evaluate the sum

E(x) = $30.0

Hence, the worker's expected weekly bonus is $30.0
