Answer:
Step-by-step explanation:
<u>Formulas used:</u>
- sin θ = sin (180 - θ)
- sin θ = opposite/hypotenuse
<u>Opposite:</u>
- y- coordinate of given point = 21
<u>Hypotenuse:</u>
- √x²+y² = √20²+21²= √841 = 29
<u>Then</u>
Correct choice is D
The line of best fit for the information in this graph is:
f(x) = 200x + 100.
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator.
For this problem, the points (t,v) are given as follows:
(2, 500), (3, 700), (4, 900), (5, 110)
Hence, inserting these points into a calculator, the equation is given by:
f(x) = 200x + 100.

Answer:
Step-by-step explanation:
Plot the point (4, 0) (the x-intercept) and then the point (0, -3) (the y-intercept). Draw a straight line through these two points.

smaller example: say 4 people are running for office, A,B,C, and D
first way: A is prez, B is vice
second way: A is prez, C is vice
Let;'smakeit simpler
A, B
A,C
A, D
B, A
B, C
B, D
C, A
... get it?
Now we don't wantto do that with 36 people so we do some math
Let's say we order four people; A, B,C, D
at first we have 4 choices for 1st. Once we pick a 1st, we have 3 to choose from. 4 1stpicks, from that there can be 3 2nd picks, so thetotal so far is 4*3. Once 2nd is picked, there are 2 choices for 3rd; 4*3*2. And only one choice for the lastplace; 4*3*2*1
For 36 people, we have 36 choices for prez, that leaved 35 choices for vice. but here, thank goodness, we are only picking two places; prez and vice. So we can stop there. You shoid be able to figure out what to do based on the example I gave
Answer:
y = -1/3x + 5
Step-by-step explanation:
y = -1/3x + b
3 = -1/3(6) + b
3 = -2 + b
b = 5
