Answer 1

Answer:

0.85 is the probability that you will roll an even number or odd prime number

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

A twenty-sided number cube has 10 even numbers (2, 4, 6, 8, 10, 12, 14, 16, 18, 20) and 7 odd prime numbers (3, 5, 7, 11, 13, 17, 19).

To find the probability of rolling an even number or an odd prime number

We need to calculate the total favorable outcomes (even numbers and odd prime numbers) divided by the total possible outcomes (numbers 1 to 20).

Total favorable outcomes = 10 (even numbers) + 7 (odd prime numbers) = 18

Total possible outcomes = 20

Probability = Total favorable outcomes / Total possible outcomes = 17 / 20 = 0.9

Hence, 0.85 is the probability that you will roll an even number or odd prime number

Answer 2

Answer:

Answer:

0.85

Step-by-step explanation:

total samples cases = 20

chances that are even or odd prime are 17 chances

2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20

probability = 17/20

= 0.85

A Ferris wheel has a diameter of 56 ft. how far will a rider travel during a 4-minute ride if the wheel rotates once every 20 seconds? use 22/7 for pi

Answers

First calculate the circumference. Usually this is the diameter times pi, but since we are told to estimate pi, the circumference equals 56 * 22/7 or 176 feet.
In 4 minutes, 4 * 60 = 240 seconds pass. In this time, a 20 second period will occur 240/20 = 12 times.
So we know that the rider rotates 12 times and each rotation takes them 176 feet, meaning that they will travel 12 * 176 = 2112 feet

How to solve 2/4 of 4

Answers

2/4 simplified is 1/2
1/2 of 4 = 4/2
4/2 simplifies to 2/1
2/1 is 2

4 can be written as 4/1.
Now multiply 2/4 * 4/1 = 8/4
8/4 can be reduced by 4
8/4 = 2
4/4=1
So u have 2/1 = 2
