Answer:
1/5
Step-by-step explanation:
We can find the slope of a line using two points by
m = (y2-y1)/ (x2-x1)
= (3-2)/(4 - -1)
(3-2) /( 4+1)
1/5
Daniela made her error on step 3 because it says:
"Find the ratio of the differences of the means compared to the mean absolute deviation.
She didn't find the difference between the today and last week means. She just put the mean as a whole.
Answer:
x = 5.2
Step-by-step explanation:
x/(13-x) = 2/3
3x = 2(13 - x)
3x = 26 - 2x
3x + 2x = 26
5x = 26
x = 26/5
x = 5.2
Answer:
36π
Step-by-step explanation:
The area of a circle is given as:

where r = radius of the circle
The area of a sector of a circle is given as:

where α = central angle in radians
Since
is the area of a circle, A, this implies that:

A circle has a sector with area 33 pi and a central angle of 11/6 pi radians.
Therefore, the area of the circle, A, is:

The area of the circle is 36π.
17- 6 11/12
borrow from the 17 and use a common denominator
16 12/12 - 6 11/12
10 1/12
