[tex]A) 14.89~ units[/tex]

Step-by-step explanation:

[tex]AD=C=3.42~, AC=d=4.57, ~CD=a=4.39[/tex]

[tex]S=\frac{C+d+a}{2} =\frac{3.42+4.57+4.39}{2} =6.19[/tex]

A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow , and purple. The spinner is spun several times, and the results are recorded below: Spinner Results Color Frequency 18 15 Red Blue Green Yellow Purple 20 18 13 Based on these results , express the probability that the next spin will land on purple as a decimal to the nearest hundredth.

Answers

Answer:

0.15

Step-by-step explanation:

The probability would be the amount of times the pointer landed on purple divided by the total times the pointer was spun.

This would be 13/(18+15+20+18+13) = 13/84 = 0.15476

The probability that the next spin will land on purple nearest hundredth will be 0.15.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

The table is given below.

Color       Frequency

Red              18

Green          15

Blue            20

Yellow         18

Purple          13

Based on these results, the probability that the next spin will land on purple in decimal to the nearest hundredth is calculated as,

P = 13 / (18 + 15 + 20 + 18 + 13)

P = 13 / 84

P = 0.15

The probability that the next spin will land on purple nearest hundredth will be 0.15.

B. {7.88}

Step-by-step explanation:

[tex]\frac{6}{x}= \frac{10}{6}[/tex]

x · 10 = 6 · 6

10x = 36

10x ÷ 10 = 36 ÷ 10

x = 3.6
