Jake is skipping stones onto a pond. each time he flings a stone in, he counts the number of times it skips over the water. the number of skips he recorded for each stone were 3, 2, 1, 3, 2, 5, 4, 1, 3, 3, 4, 1, 5, 4, and 2. which measure should jake use to find the middle number of times the stone skipped on the water? a. interquartile range b. mean absolute deviation c. median d. mode e. mean

Step-by-step explanation:

Notice that the middle number of times refers to the median.

In statistics, the median is defined as the central value of a data set, literally, the value which is placed in the exact middle.

To find the median, first we need to order the data set.

1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5

Then, we find the value in the exact middle. Notice that 3 is the middle number, because it has 7 values at each side. So, the median is 3.

Therefore, the right answer is C. median, because that's the statistic measure that indicate the middle number of a data set.

it is x=-4

i think the amount would be $140.62
