Answer: variable is distributed normally, then approximately two-thirds of the population will within plus or minus one standard deviation of the mean

Step-by-step explanation:

The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.

The measurements of a rectangular prism are shown.
avanturin [10]
In a rectangular prism, surface area is calculated by multiply all the faces of the prism that you can touch


Becuase there's four faces that have the measurement of 5*3, you do 4(5*3) and because there's only two faces that have the measurement of 3*3, you do 2(3*3)

Which becomes 4(5*3)+2(3*3) which is 78

The function g(x)=-(x)^2+5. The function f(x)=-g(x+2).
Vitek1552 [10]
Short Answer f(x) down 5 units, left 2 units and right side up from g(x)
Step One

Find out what -g(x+2) is.
There are two steps to this. The first is to deal with the minus sign
(g(x)) = - x^2 + 5. Be very careful what you do next. 
Put brackets around both terms on the right.
g(x) = (-x^2 + 5) Now put the minus sign in front of g(x) and another one in front of the brackets.
-g(x) = - (-x^2 + 5) Remove the brackets.
-g(x) = x^2 - 5 

<em>Result</em>
So far g(x) moves down 5 units and opens upward. 

Step Two
The second step is to see what the x + 2 does.
-g(x + 2) = (x + 2)^2 - 5

The final result is that the graph opens upward, moves left 2 spaces and down 5.

There is a graph enclosed to show you the key steps.
The red graph is g(x) = x^2 - 5
The blue graph is g(x+2) = (x+2)^2 - 5
