Student grades on a chemistry exam were: 77, 78, 76, 81, 86, 51, 79, 82, 84, 99 Required:

a. Construct a stem-and-leaf plot of the data.

b. Are there any potential outliers? If so, which scores are they? Why do you consider them outliers?"

Step-by-step explanation:

A) Stem-and-leaf plot

stem          leaf

5                 1

7                 6,7,8,9

8                 1,2,4,6

9                  9

B) Outlier

Could consider 51 an outlier.

answer: 59

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
