Answer:
I can't answer if you don't give enough information. Sorry!
Step-by-step explanation:
Recall that the mean of a given set of numbers is the sum of the numbers divided by the number of numbers, therefore, the mean of the dataset is:

Now, the range of a data set is the difference between the maximum and the minimum, in this case, the maximum is 99, and the minimum is 15 therefore, the range is:

Finally, the standard deviation is given by the following formula:

where N is the sample size, x_i is an element of the set, and x^- is the mean. The standard deviation of the set is:

<h2>Answer: </h2>

As I understand, you need to know the relationship between the area of similar figures. Two shapes are similar if we can turn one into the other by moving, rotating, flipping, or scaling, so this means we can make one shape bigger or smaller.
From math, if we call
the scaling factor, then the area of one figure (
) divided by the area of another similar figure (
) will be equal to the scaling factor squared. In other words:

Answer:
FALSE, when we plug in the coordinates (-3,7) in the equation, it isn’t true. Therefore, it isn’t the solution.
Step-by-step explanation:
You plug the coordinates (-3,7) in the equation and see if it’s true
Y= -3x-2
7=-3(-3)-2
7=9-2
7=7
Y-10=2/3(x-6)
7-10=2/3((-3)-6)
-3=-7 (FALSE!!!)
Answer:
313.9
Step-by-step explanation:
running around the field is 100+100+145+145 = 490
across the field:
(100)^2 + (145)^2 = c^2
10000+21025 = c^2
c=176.1
490 - 176.1 = 313.9
