Find the Mean, Median, Mode & Range. If possible, round to the nearest tenth. 3, 8, 7, 2, 4, 8, 3, 4​
Masja [62]

Answer:

Mean- 4.9

Median- 4

Mode- 3,4,8

Range- 6

Step-by-step explanation:

The mean of a sequence is the average amount. This is equal to all of the terms' sum divided by the number of terms. So, to find the mean add 2+3+3+4+4+7+8+8, which equals 39. Then, divide by 8 because that is the number of terms. Therefore, the mean is 4.9.

The median is the number in the middle of the sequence. To find the median order the sequence from least to greatest and find the middlemost number. In this case, that is 4.

The mode is the number that appears most often. In this sequence, 3, 4, and 8 all appear twice.

The range is the difference between the minimum and maximum. So, subtract 2 from 8 to get 6.

Which equation are true for x=-2 and x=2 check all that apply
ki77a [65]
1 it is true
{x}^{2} - 4 = 0 \\ {x}^{2} = + 4 \\ x = \sqrt{4} = 2
2 it's not true
{x}^{2} = - 4
3 it's not true
3 {x}^{2} + 12 = 0 \\ 3 {x}^{2} = - 12 \\ {x}^{2} = \frac{ - 12}{3} = - 4 \\
4 it's true
4 {x}^{2} = 16 \\ {x}^{2} = \frac{16}{4} = 4 \\ x = \sqrt{4} = 2
5- it's true
{2(x - 2)}^{2} = 0 \\ {(x - 2)}^{2} = 0 \\ x - 2 = 0 \\ x = 2
