Fifty-five percent of the members of the junior varsity swim team wear glasses. Of the team memebers who do not wear glasses, 30 percent of them are in the 10th grade.

To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade?

14%
17%
55%
67%

14%

Step-by-step explanation:

Step 1:

Let x be the total number of members in the junior varsity team

Given that Fifty-five percent of the members wear glasses, we have

the total number of members wearing glasses = 55% * x = 0.55 x

So

the total number of members not wearing glasses = x - 0.55 x = 0.45 x

Given that 30% of the members not wearing glasses are in 10th grade,

Number of members in 10th grade not wearing glasses = 0.45 x * 30% = 0.45 x * 0.3 = 0.135 x

Step 2 :

To find the probability that any chosen member at random does not wear glasses and is in the 10th grade

probability = no. of favorable outcomes / total no. of outcomes  

                 = 0.135 x / x = 0.135

This rounded off to percentage = 13.5% which is approximately  14%

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
