Answer:

C

Step-by-step explanation:

They are trying to deceive you into not choosing the star that is largest when written as 10^17.

When you rewrite the givens so that the power is 10^17 then the table will look like this.

1.76 * 10^17

2.213 * 10^17

3.142 * 10^17

1.255 * 10^14

It obviously isn't D.

It should be C

Calculate the mean given the frequency table
ratelena [41]

Answer:

15.6

Step-by-step explanation:

First, multiply the midpoint of each class by its frequency, as follows:

            Class      midpoint   frequency   midpoint*frequency  

            0-9         4.5             24                4.5*24 = 108

            10-19      14.5            20                14.5*20 = 290

            20-29    24.5           32                24.5*32 = 784

Total                                      76               1182

The mean is computed as the division between the addition of the "midpoint*frequency" column by the addition of "frequency" column.

mean = 1182/76 ≈ 15.6
