From x equals five to nine, the y value changes as follows
+10,+2,+1,+3
Assuming that "average" implies the mean, the sum of all four values is 15. Then divide 15 by the four values added = 15/4 = 3 3/4 or 3.75

Hansel opened a bank account. He deposited $52.50 into his account every month for 10 months. He used $20.50 every month to pay

Maksim231197 [3]

$52.50 and subtract $20.50 to get $32 and multiply that by 10 (months) to get $320 and divide it by 2 and your final answer is; $160.00

Answer:

$n ^{2} + 7n + 1 \\ where \: the \: value \: of \: n = - 3 \\ n ^{2} + 7n + 1 \\ = - 3^{2} + 7( - 3) + 1 \\ = - 9 - 21 + 1 \\ = - 29$

The data list shows the scores of ten students in Mr. Smith's math class. 61, 67, 81, 83, 87, 88, 89, 90, 98, 100 What is the st

Sample standard deviation

Mean of data = 84.4

Calculate deviations from the mean = 23.4, 17.8, 3.4, 1.4, -2.6, -3.6, -4.6, -5.6, -13.6 and -15.6

Squaring these deviations; we get 547.56, 316.84, 11.56, 1.96, 6.76, 12.96, 21.15, 31.36, 184.96, 243.36

Adding these we get 1378.47

As its a sample Std Dev we divide by 10 - 1 = 9. For the popklation Std Dev we divide by the number of scores (10).

Std Deviation for sample = sqrt ( 1378.47 / 9) = 12.4 to nearest tenth (answer)

Population Std Dev = sqrt (1378.47 / 10) = 11.7 answer

Theres a lot of arithmetic there so hope i haven't slipped up anywhere!

I think the correct answer would be B. The graph in the attached image would most likely be described as a bimodal symmetric. A bimodal graph would be a graph which has two peaks. From the image, we have 3 peaks so it should be a multimodal but it is not in the choices the closest would be a bimodal one. Each group of the peak shows a symmetrical distribution since the left side and the right side are almost mirrors of each other which is seen for all the three peaks. So, the graph should be a bimodal symmetric distribution.
