What is the square root of negative 16?
-8i
-4i
4i
8i

To find the sqrt of -16, you must first take out i from the equation to make the 16 positive. That equals:

i sqrt16

Then, solve sqrt16 to get 4. It then becomes:

4i

That is the final answer. If you need more help, comment below and I will do what I can.

The five-number summary of the data presented on the stem-and-leaf plot are:

The minimum data value is: 40The first quartile is: 43The median data value is: 61The third quartile is: 65The maximum data value is: 97

The data is presented in a stem and leaf plot.

To determine the five-number summary, first, we need to list out all the data point for the weight of each dog.

For the first row: 4 | 0 1 3

The weights are: 40, 41, 43

For the second row: 5 | 0 8

The weights are: 50, 58

For the third row: 6 | 1 2 3 5

The weights are: 61, 62, 63, 65

For the fourth row: 7 | 8

The weight is: 78

For the last row: 9 | 7

The weight is: 97

Thus, all the data for the weights are:

40, 41, 43, 50, 58, 61, 62, 63, 65, 78, 97

We can now determine the five-number summary as follows:

The minimum data value is: 40

(40,) 41, 43, 50, 58, 61, 62, 63, 65, 78, 97

The first quartile is: 43

40, 41, (43,) 50, 58, 61, 62, 63, 65, 78, 97

The median data value is: 61

40, 41, 43, 50, 58, (61,) 62, 63, 65, 78, 97

The third quartile is: 65

40, 41, 43, 50, 58, 61, 62, 63, (65,) 78, 97

The maximum data value is: 97

40, 41, 43, 50, 58, 61, 62, 63, 65, 78, (97)
