Wayne asked every student in his class how many siblings (brothers and sisters) they had. the survey results are shown in the table below. (wayne included himself in the results.)

what is the probability that a randomly selected student does not have any siblings?

question 4 options:

0/32

1/8

7/8

14/32

The correct answer is 1/8

Step-by-step explanation:

In order to find this, we need to find out how many people have 0 siblings (4 people).

Now we need to find the total number of people surveyed. We can do this by adding all the numbers in the bottom row.

4 + 5 + 14 + 6 + 3 = 32

Now divide the number with 0 siblings by the total.

4/32 = 1/8

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
