Answer:
18 °F
Step-by-step explanation:
The means are calculated in the usual way: add up the numbers and divide by the number of them. When there are a bunch of numbers, it is convenient to let a calculator or spreadsheet compute the mean for you.
In the attached, we see the mean for week 1 is 52°, and in week 2, it is 70°. The mean is 70° -52° = 18° greater in week 2.
Answer:
x=7
Step-by-step explanation:
2x=14
divide both sides by 2
x=7
2a² + ab + 2b + 4a² - 3ab + 9
combine like terms:
2a² + 4a² + ab - 3ab + 2b + 9
6a² - 2ab + 2b + 9
Answer:
m = -4
Step-by-step explanation:
We are given that a line intersects the points (-2, 9) and (3, -11).
We want to write the slope of this line.
The slope (m) can be found using the formula , where and are points.
Even though we have everything we need to calculate the slope, let's label the values of the points to avoid any confusion & mistakes.
Now substitute these values into the formula (remember that the formula has subtraction).
m=
m=
Simplify.
m=
Subtract the values on top.
m=
Now add the values on the bottom together.
m=
Now divide -20 by 5.
<u>m = -4</u>
To solve for the variable , we have to make it alone. The first thing we do is add to both sides of the equation:
Now add to both sides:
Finally, divide both sides by 16 to get the final answer:
Therefore,
Hope this helps!
