It's all explained below :)
Step-by-step explanation:
So first we need to go to a graphing calculator! I usually use Desmos to do my stats stuff. You'll wanna head to their linear regression calculator (I can't add a link, but just google Desmos linear regresion and it'll pop up).
Put the points into the table. Lines of best fit have the equation y1 ~ bx1+a, so put that in the box right below the table, where you see another equation already written- just edit it. We see all the other numbers listed below that, so we know that b=-0.894 and a=13.599, so the line of best fit is -0.9x + 13.6 = y when you round those numbers.
The correlation coefficient is represented by the letter r. r is shown below as well, and is -0.964. Strong correlations are represented by a value close to the number 1, so this is strong, as it's very close. It is negative because of its sign. Correlation coefficients don't go over the number 1 or below -1, so be careful. I hope this was helpful! If you need any more clarification just let me know.

To join a gym, there is a monthly fee of $12 and a $5 fee per workout class you take. Which of the following functions would show the cost, in dollars, for a month that she takes w workout classes?
C(w) = 12w
C(w) = 5w + 12
C(w) = 12 + 5w
C(w)= 17w
Answers
Answer:
[tex]C(w) = 5w + 12[/tex]
[tex]C(w) = 12+5w[/tex]
Step-by-step explanation:
Given information:
- Monthly fee of $12
- $5 fee per workout class
- [tex]w[/tex] represents the workout classes taken for a month
- - - -
With the given information, we can conclude that [tex]C(w)=[/tex] workout fee + monthly fee.
Workout fee = [tex]$5w[/tex]
Monthly fee = [tex]$12[/tex]
∴ [tex]C(w) = 5w + 12[/tex] or [tex]C(w) = 12+5w[/tex] (they are the same)

A window washer cleaned 38 windows in 2 hours. At this rate, how many windows did he clean in 7 hours? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value
Answers
Answer:
133 windows
Step-by-step explanation:
It is given that,
A window washer cleaned 38 windows in 2 hours.
We need to find how many windows did he clean in 7 hours.
2 hours = 38 windows
1 hour = 19 windows
For 7 hours, multiply 19 and 7.
7 hours = 19 × 7 windows
= 133 windows
Hence, in 7 hours he can clean 133 window

What’s the slope of the parallel line that passes through (-13, -2) and (14, 13).
Answers
Answer: 5/9
Step-by-step explanation:
Slope formula: y2-y1/x2-x1
y2= 13
y1=-2
x2=14
x1=-13
OR
y2=-2
y1=13
x2=-13
x1=14
(You'll get the same answer either way so it doesn't matter which one you choose, I'm gonna go with the first one.)
m=y2-y1/x2-x1
=13-(-2)/14-(-13)
=13+2/14+13
=15/27
=5/9

the total cost of three bottles is $2.31 because each bottle cost the same amount we can divide by 3 to get our answer.
4(x+6)-3x=26 what is the x value
Answers
Answer:
x=2
Step-by-step explanation:
4 (x + 6) - 3x = 26
solve the parenthesis
4x + 24 - 3x = 26
subtract 24 from both sides to get x by itself
4x - 3x = 2
solve
x = 2
by simplifying both sides of the equation, then isolating the variable.

Solve the system of equations by using the elimination method.
4x + 6y = 2
–4x + 4y = -12
Enter the solution as an ordered pair.
Answers
Answer:
(2, -1)
Step-by-step explanation:
We can add the first equation by the second
(4x + 6y = 2)+(-4x + 4y = -12)=
10y=-10
we divide both sides by 10 to get
y=-1
We plug -1 in the second equation to get:
-4x+4(-1)=-12
-4x-4=-12
-4x=-8
Now, we divide both sides by -4
x=2
