A spinner has five sections, labeled A, B, C, D, and E. The spinner is spun 45 times, and the results are recorded in the table.What is the experimental probability of the spinner’s landing on C? Round to the nearest percent, if necessary.

Outcome A B C D E
Number of trials 6 10 8 12 9

A.8%
B.18%
C.20%
D. 24%

Answers

Answer 1

Answer:

The experimental probability of the spinner’s landing on C is 18%

The total number of spins is:

n = 45

From the table, the outcome of C is:

C = 8

So, the experimental probability of C is:

P(C) = n(C)/n

This gives

P(C) = 8/45

Divide

P(C) = 0.1777

Express as percentage

P(C) = 17.77%

Approximate

P(C) = 18%

Hence, the experimental probability of the spinner’s landing on C is 18%

You have a can that is in the shape of a cylinder. It has a volume of about 1,738 cubic centimeters. The height of the can use 23 centimeters. What is the approximate length of the radius? Use 3.14 for pi

Answers

Answer:

~8.7

Step-by-step explanation:

So we know that the formula for volume is 3.14 * r^2 * h.

So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.

The square root of 75.6 is ~ 8.7

A bar graph shows that sports books received 9 votes. If the scale is 0 to 20 by twos, where should the bar end for the sports books?

Answers

The answer to this question would be: between 8 and 10

In this question, the sports book get 9 votes but the ranges are made by twos which mean only even number will be placed on the track. The closest even number from 9 would be 8(1 number below) and 10(1 number above). So, the bar should be between 8 and 10
