The probability that the student has a part-time job, given that they have a cell phone is 5/8

<h3>What is probability</h3>

Probability is the likelihood or chance that an event will occur.

Given the following parameter:

Total student = 80%
Part-time jobs = 45%
Those with both a cell phone and a part-time job = 30%

Student will cellphone only = 80 - 30 = 50%

The probability that the student has a part-time job, given that they have a cell phone is 50/80 = 5/8

1. If a bicycle wheel has a diameter of 15 in. How far will the wheel rotate in 10 rotations?

WARRIOR [948]

Answer:

150 pi inches or 471.239 inches traveled

Step-by-step explanation:

First, close your eyes, and think about the distance a bike travels after one rotation of the wheel.

You will come to the realization that a full rotation of the wheel makes you travel the circumference of the wheel

The formula for circumference is 2(pi)(r) or (pi)(diameter)

We are given diameter, so let's find distance traveled for one rotation

pi(15 inches) = 15pi inches per rotation.

There are 10 rotations, so:

(15pi inches/rotation)(10 rotations) = 150pi inches travelled

150 x pi = 471.239 inches traveled

If a baseball player has 5 hits in 20 at bats, what is the probability in the decimal to the thousandths place that he will get

k0ka [10]

Answer:

$Probability = 0.250$

Step-by-step explanation:

Given

$Hits = 5$

$Bats = 20$

Required

Determine the probability of hit in next at-bat

This question illustrates theoretical probability and the required probability is calculated using:

$Probability = \frac{Events\ Occurrence}{Trials}$

In this case, we have:

$Probability = \frac{Hits}{Bats}$

$Probability = \frac{5}{20}$

$Probability = 0.250$
