Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?

The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
Here, we have,
We are given the scatter plot which shows the distance he has run and the time it took for each run.
We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?
One way to predict the time is by drawing a line that best fits the given data.
As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.
Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

Step-by-step explanation:
I = Prt where I is the interest P is the principle r is the rate and t is the time
I = 400 * (.02) * 6
I = 48
The amount in the account is the interest plus the original amount
400 +48
448
Answer:
$ 448
Step-by-step explanation:
amount that Elena deposit (P) =$ 400
rate of interest (R)=2%
time (T)=6 years
formula to find interest is
Interest = PTR/100
=$400*6*2/100
=$4800/100
=$48
Total amout she receives after 6 years is
Amount = Interest + Principal
=$48 + $400
=$448
What is the value of x and y?
Answers
Answer:
[tex] x=\boxed{2} [/tex]
[tex] y=\boxed{4}[/tex]
Step-by-step explanation:
[tex] \begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases} [/tex]
From equations (1) & (2), we find:
6x - 8 = - 3x +10
[tex] \therefore 6x+3x = 8+10[/tex]
[tex] \therefore 9x = 18[/tex]
[tex] \therefore x =\frac{18}{9}[/tex]
[tex] \therefore x = 2[/tex]
Plug x = 2 in equation (1)
y = 6(2)-8 = 12-8 =4
So,

What is the Golden Rule for solving equations?
Answers
Answer:
Do unto one side of the equation, what you do to the other!
Step-by-step explanation:
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.
Answer:
Keeping the equation balanced.
Step-by-step explanation:
You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

What is the area of the figure below?
Answers
explanation: by separating the figure into easier pieces, simple triangles and rectangles, this problem becomes much easier.
by looking the overall length of the figure, we get 7, if you cut off the big rectangle in the middle from that seven, you end up with a diamond with a height of 10 and a length of 4. multiply those together to get the area of the points on either side.
10 x 4 = 40
now looking back at the rectangle, by adding up the heights, you get a height of 16. multiply this with the length of 3 and you get 48.
add the two and you get the total area.
40 + 48 = 88
Answer:
68 in
Step-by-step explanation:
Because the area of the squares is 3 x 3 = 9 and because there are two squares it is 18. The area of the central figure is 50 because i divided it into 4 triangles and 2 rectangles, each rectangle is 15 in and each triangle is 5 in so 15 x 2 = 30, 5 x 4 = 20 and 30 + 20 + 18 = 68

Step 2: 47
Step 3: 84
Step 4: 114
Step-by-step explanation:
Step 2: The width is 21, and the length is 36.
Sum is addition, so it would be 21 + 36.
21 + 36 = 47
Step 3: 47 x 2 = 84
Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.

Answers
Answer:
1) The mean is actually 31
2) True, the mean would be about 35.
3) True, the mean would change because more medals were added for the USA.
4) True, the mean would be effected because two is added. It results in a increase
All the statements given for the data are true.
What is data estimation?True. The mean is calculated by adding up the total number of medals earned from 1972 to 2000 (including 1972 and 2000) and then dividing by the total number of years, which is 29. If the data for 1980 is removed, the total number of medals earned and the number of years both decrease by 1, so the mean remains the same.
False. The mean is calculated by adding up the total number of medals earned from 1972 to 2000 and then dividing by the total number of years, which is 29. Removing the data for 1980 would decrease the total number of years to 28, so the mean would increase if the total number of medals earned remains the same.
Not enough information. The number of silver medals earned in 2004 is not given, so it is impossible to determine if earning more than 31 silver medals would increase the mean.
True. The mean is calculated by adding up the total number of medals earned from 1972 to 2000 and then dividing by the total number of years, which is 29. If the USA had earned 2 more medals in 1988, the total number of medals earned would increase by 2, which would increase the mean.
