Is 1/6 or 1/7 larger

mash [69]

1/6 is larger. Say you have a pizza, if you had 7 pieces of pizza, they would be smaller than 6 slices of pizza.

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.

Please asap I need this for a test

Answer:

Step-by-step explanation:

(f O g) this basically means that the input x first goes trough the function g and then f. Like f(g(x)).

So when x went trough g, you got the output g(x) and then this went trough f and you got f(g(x)) = -8 = 'f(x)'.

With this in mind you can retrace your steps by first looking at what input can get -8 as an output, for f this is -4. this means g(x) = -4

Then you look at what input (this is the x you're looking for) gets you the ouput -4. Looking at the second image you'll picture see that it's the input 3.
