The box-and-whisker plot shows the heights (in inches) of the players on a soccer team. What fraction of the heights are at least 68 inches?

1/2

Step-by-step explanation:

Please find attached the diagram used in answering this question

A box plot is used to study the distribution and level of a set of scores

the scores are distributed into 4 groups. Each group has a value of 25%

the box plot consists of two lines and a box. the two lines are known as whiskers. the whiskers represent scores outside the middle 50%

On the box, the first line to the left represents the lower quartile. 25% of the score represents the lower quartile

the next line on the box represents the median. 50% of the score represents the median

The third line on the box represents the upper quartile. 75% of the scores represents the upper quartile

In this question, 68 is on the second line which represents the median. Thus 1/2 of the height are at least 68 inches

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

answer is c

step-by-step explanation:

81/12=324/x

x=48
