The sections on a spinner are numbered from 1 through 8. If the probability of landing on a given section is the same for all the sections, what is the probability of spinning a number less than 3 or greater than 5 in a single spin?

5/8

Step-by-step explanation:

There are two numbers from one to eight that are less than three (1 and 2). So 2/8 of the numbered sections are less than three.

There are three numbers from one to eight that are greater than five (6, 7, and 8). So 3/8 of the numbered sections are greater than five

Probability of getting a number less than three: 2/8

Probability of getting a number greater than five: 3/8

Probability of getting either in a single spin = 2/8 + 3/8 = 5/8

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
