Complete the chart to find the mean, variance, and standard deviation. Remember to use commas and round numbers to the nearest t

vitfil [10]

Answer: The mean of the data is 433.75, variance of the data is 99667.19 and the standard deviation of the data is 315.7011.

Explanation:

The given data is 900, 35, 500 and 300.

The number of observation is 4.

Formula of mean is,

$\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}$

$\bar{X}=\frac{900+35+50+300}{4} =433.75$

The formula of variance is given below,

$\sigma^2=\frac{1}{n}\sum{(X-\bar{X})^2}$

$\sigma^2=\frac{398668.75}{4}$

$\sigma^2=99667.19$

The variance of the data is 99667.19

$\sigma=\sqrt{99667.19}$

$\sigma=315.7011$

The standard deviation of the data is 315.7011.

The other information or values of given chart is shown in the attached table.

Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood.

Orlov [11]

Answer:

Step-by-step explanation:

Two triangular ends
Area of one = 1/2 b * h
b =1.2
h =0.9
Area = 1/2 * 1.2 * 0.9 = 0.54 sq meters
Area of 2 = 2 * 0.54 1.08

Area bottom

L = 3.5 m
w = 1.2
Area = L * W
Area = 3.5 * 1.2
Area = 4.2

Area Back

L = 3.5
W = 0.9
Area = 3.5 * 0.9
Area = 3.15

Area Slanted piece

L = 3.5
w = 1.5
Area = L * W
Area = 3.5 * 1.5 = <u> 5.25</u>

Total = 5.25 + 3.15 + 4.2 + 1.08 = 13.68
