Complete the chart to find the mean, variance, and standard deviation. Remember to use commas and round numbers to the nearest tenth. X X X - X (X - X)2 1. 900 = 466.2 = 4,382.4 The mean is 433.8 2. 35 = -398.8 = 159,041.4 The variance is 99,667.2 3. 500 = 66.2 = The standard deviation is 4. 300 = -133.8 = n = Σ X = X = Σ (X - X)2 = 398,668.6

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

if x = 1, then the answer is 3.5

the answer will be $181.5

hope this !
