Using measures of central tendency:
5. write and solve an equation to find the value of "x". 3.8, 4.2, 5.3,x; mean 112
7. write and solve an equation to find the value of "x". 100, 121, 105, 113, 108, x; mean 112
9. find the range. 12, 15, 17, 28, 30
11. find the range. -12, -15, 5, 3, -2, 0, -7
13. for each list of data, find the range and the mean. use the range to compare the spread of the data.
list 1: 64, 43, 55, 28, 71. list 2: 48, 53, 61, 47, 51

Step-by-step explanation:

5)

Mean, 112= (3.8+4.2.5.3+x)/4

448 =13.3 +x

x = 448-13.3=434.7

7)

Mean, 112= (100+ 121+ 105+ 113+108 +x)/5

560 =547 +x

x = 560-547=13

9) 12, 15, 17, 28, 30

Range = highest - lowest =30-12

=18

11) -12, -15, 5, 3, -2, 0, -7

Range = highest - lowest =5--15

=20

64, 43, 55, 28, 71

Mean = (64+43+55+ 28+ 71)/5

=52.2

Range =71-28=43

8, 53, 61, 47, 51

Mean = (8+53+61+ 47+ 51)/5

=220/5= 44

Range =61-8=53

Spread = 53-43=10

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
