The average score is 500 points and the standard deviation is 50 points.Mean - 2 SD = 500 - 2 * 50 = 500 - 100 = 400It means that more than 400 on the standardized test is more than: Mean - 2 Standard deviations.For the Normal distribution: 100% - 2.5 % = 97.5% = 0.975.Answer: The probability that student scores more than 400 points is 0.975.

Answer:
Expression for perimeter of rectangle is:

Step-by-step explanation:
Width of rectangle is given as
centimeters and
length of the rectangle is given as
centimeters.
To find:
The expression to represent the perimeter of rectangle in centimeters.
Solution:
First of all, let us have a look at the formula to calculate the perimeter of a rectangle.
Perimeter of a polygon is equal to sum of all the sides.
In rectangle, we have a total of 4 sides, 2 sides equal to the width and 2 sides are equal to the length of rectangle.
Therefore, perimeter of a rectangle is equal to twice the sum of width and length of the rectangle.
So, formula:

Where
is the length of rectangle and
is the width of rectangle.
Putting the values of length and width as given in the question statement to find its perimeter:

Hey there!
To find the x-value of the midpoint, you add the two x-values of the endpoints and the divide the result by two.
-12+0=-12
-12/2=-6
So, the x-value of our midpoint is -6.
To find the y-value of a midpoint, you do the same thing as with the x-values but with the y-values.
2+14=16
16/2=8
Our y-value is 8.
Therefore, our midpoint is (-6,8)
I hope that this helps!
