Answer:

no mode

The median and mode are 12

Step-by-step explanation:

The mode is the number that appears most often

Since no number repeats there is no mode

The mean is the average

Add up all the numbers

(12+12+12+12+13+13+15)/7 = 89/7 = 12 5/7

The median is the middle number

There are 7 numbers

7/2 = 3.5

The 4th number is the median

The 4th number is 12

The mode is the number that appears most often which is 12

astra-53 [7]

Answer: C.186


Step-by-step explanation:

1. You know that he read 6 books when he was 6 years old and every year he doubled the number of books he read the previous year.

2. Let's call n the number of book he read each year and n_t the number of books he read between the ages of 6 and 10, then:

 - At 6 years old:

n=6

- At 7 years old:

n=6*2=12

- At 8 years old:

n=12*2=24

- At 9 years old:

n=24*2=48

- At 10 years old:

n=96

The total books he read between the ages of 6 and 10 is:

n_t=6+12+24+48+96\\n_t=186
