The ages of two exercise groups at a local fitness center are listed below group a: 37, ,32, 41, 42, 36, 44, 45 group b: 26, 40, 38, 36, 42, 40, 40, 36 which statement about the data is true a. the mean age is the same for both groups b. the range of ages is greater in group a than in group b c. the mode of the ages for both groups is 36 d. the median age is the same for both groups

(B) The range of ages is greater in group A than in group B.

Step-by-step explanation:

A. The mean of the group A is:

                                                  =

                                                  =

   The mean of the group B is:

                                                =

                                                =

Hence, the mean age is not same for both the groups.

B. The range of group A is: 45-32=13

   The range of group B is: 42-26=12

Hence, the range of the ages is greater in group A than in group B.

C. The mode is the number which occurs frequently in the given data. Therefore, the mode pf the ages in group A is not there because no number is occurring frequently in group A.

The mode of the group B is 40 because 40 is occurring frequently in group B.

D. The median is the middle number in data when listed in ascending order.  Therefore, arranging the data of group A :32,36,37,41,42,44,45, the median is 41.

Group B: 26,36,36,38,40,40,40,42, the median is =.

Hence, the median age is not same for both groups.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

they can both be solutions depends on the equation
