The approximate hourly wage of a person who has worked at the company for 15 years is $

Answers
Answer:
y= 0.5x + 8.2
$13.6 per hour
Step-by-step explanation:
(Is it weird that I had the same exact question? Maybe not. But I also found another person with the same question as me. It was a different question though. This is probably too late. But I'm just gonna try to answer it for anyone who needs it.
"Linear regression" is just a fancy word for scatter plots. Scatter plots take place in graphs. The dots or plots are scattered and the way they are scattered means something. If it's going down, it's negative, up it's positive, and if it's scattered, it has no corrolation.
Also, you should have learned this in 9th grade. So, check your notes.
If you don't have it, WRITE IT!!!
To find it in your calculator:
1. Go to "Lists and Spreadsheets"
2. Rename the first column "x" and the second on "y"
3. Write all of your numbers in the right column
1, 5, 3, 7 under the "x"8.67, 10.50, 9.58, 11.41 under the "y"4. Move your cursor to an empty cell
4. Click: "MENU" #4 #1 #3
5. Rename the correct rows "x" and "y" and press enter
6. Now you can find "m" and "b"
7. Then move your cursor to an empty cell and click "doc" "insert" #7
8. Find the x-axis and find "x"
9. Find the y-axis and find "y"
10. Now press "MENU" #4 #6 #1
And you found your y=mx+b: y=0.5x+8.2
Now, how much money per hour.
So you've found your m and b but now you have to:
1. Replace y with 15 and solve it
15=0.5x+8.2-8.2 -8.26.8=0.5xDivide 0.5 on both sides6.8/0.5=13.613.6=x$13.6 per hour

Answers
Answer:
has 3 significant figures
Step-by-step explanation:
because zeros are counted if they are between the numbers
When counting significant figures, ignore the 0s that show up before a number more than 0.
If, for example, a number is 0.03067, then there are 4 significant figures, because the first two 0s are ignored but the 0 after 3 is counted!

1.4-28/x
Solve for x
Answers
Answer:
20
Step-by-step explanation:
1.4-28/x = 0
bring 1.4 to the right hand side
-28/x = -1.4
bring the x to the right hand side
-28 = -1.4x
switch the positions of -28 and -1.4x
-1.4x = -28
divide -28 by -1.4
x = -28/-1.4
x = 20

The larger of two consecutive ODD numbers is one less than twice the smaller number. Find the larger of the two numbers.
Answers
Answer:
5Step-by-step explanation:
z - any integer
2z+1 - any odd integer (the smaller one)
2z+1+2 = 2z+3 - odd integer consecutive to 2z+1 (the larger one)
2(2z+1) - twice the smaller number
2(2z+1) - 1 - one less than twice the smaller number
2(2z+1) - 1 = 2z + 3
4z + 2 - 1 = 2z + 3
2z = 2
z = 1
2z+3 = 2•1+3 = 5
check:
2z+1 = 2•1+1 = 3,
2(2z+1)-1 = 2(2•1+1)-1 = 2•3-1 = 5 = 2z+3

What is the slope of the line that contains the points (-2, 7) and (2, 3)? O A. -4 OB. 4 O C. -1 O D. 1 SUBM
Answers
Answer:
- 1
Step-by-step explanation:
[tex]slope = \frac{3 - 7}{2 - ( - 2)} = \frac{ - 4}{2 + 2} = - \frac{4}{4} = - 1 \\ [/tex]
The slope of the line that contains the points (-2, 7) and (2, 3) is -1.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have the points (-2, 7) and (2, 3).
So, the slope of line
= (3 -7)/ (2- (-2))
= (-4) / (4)
= -1
So, the slope of line is -1.

The school that Stefan goes to is selling tickets to a spring musical. On the first day of ticket sales the school sold 1 senior citizen ticket and 14 student tickets for a total of $225. The school took in $120 on the second day by selling 7 senior citizen tickets and 1 student ticket. What is the price each of one senior citizen ticket and one student ticket?
Answers
x = price of a senior ticket
y = price of a student ticket
First day: x + 14y = $225
Second day: 7x + y = $120
Let's solve this system of equations by substitution
Subtract 14y from both sides on our first equation
First day: x = $225 - 14y
Substitute this value into our second equation for x
7($225 - 14y) + y = $120
Distribute the 7
$1575 - 98y + y = $120
Combine like terms
$1575 - 97y = $120
Subtract $1575 from both sides
-97y = -1455
Divide both sides by -97
y = $15
Plug this value into our first equation
x + 14(15) = $225
Simplify
x + $210 = $225
Subtract $210 from both sides
x = $15
