Answer:
<h3>-90</h3>
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right.
Please Excuse My Dear Aunt Sally!
BOMDAS- (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
(3-21)=-18
-18(3+2)
Add.
3+2=5
-18*5
Multiply.
-18*5=-90
-90
So, the final answer is -90.
Because everyone he surveyed was on the football team, the sample population all have that in common, and so this sample is not a random one. I don't remember the name of this particular type of sample. You'd benefit from summarizing your textbook explanations of different types of samples and making sure that you can easily give an example of each and every one of them.

Note: This is done in the interior triangle as the angle will be equivalent to the other two angles.
Here's how you solve it:
You have to use the law of cosine for the interior triangle; the law of cosine is: c^2 = a^2 +b^2 - 2ab times cos (C)
Substitute each factor so that the equation now appears as so:
h^2 = 8^2 + 10^2 - 2(8)(10) times cos (80)
This will give you: h = 11.67
Now, you have to apply this to the law of sin which is a over sin(A) = b over sin (B) = c over sin (C). (Lowercase letters are the opposite side of uppercase angles.)
This will then give you:
11.67 over sin (80) = 8 over sin (S) = 10 over sin (T)
sin -1 ((8 times sin (80)) over 11.67) is equal to S
sin -1 ((10 times sin (80)0 over 11.67)) is equal to T
Because you now know the angles of S and T, you need to use the law of sin again.
t over sin (T) = s over sin (S)
t = 10 + x
s = 8 + 18 = 22
Thus, you need to substitute the variables to get this equation:
10 + x over sin (57.54) = 22 over sin (42.45)
x = 22 times sin (57.54) over sin (42.45) and next to this is -10
Thus, getting the answer of x = 17.50
Using linear function concepts, it is found that the statement that accurately describes the procedure to find the slope and the y-intercept is given by:
To find the slope, use two ordered pairs on the line and substitute into the equation 
. To find the y-intercept, begin at the origin and move vertically to the graphed line.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Given two points 
and 
, the slope is given by <u>change in y divided by change in x</u>, hence:
The y-intercept is the value of y(vertical axis) when x = 0, hence we begin at the origin and move vertically to the graphed line.
