Given:
Trapezoid with bases 10 and 20, and height of the trapezoid is 6.
To find:
The area of the trapezoid.
Solution:
We know that the area of a trapezoid is:

Where, h is the height of the trapezoid and
are bases of the trapezoid.
Putting
in the above formula, we get



The area of the trapezoid is 90 sq units. Therefore, the correct option is A.
For 11 on the dot plot its only supposed to be 2 dots because u only see two 11’s the mean is 78/15 which equals 5.2 the mode is 5 the range is 11-1 which equals 10
1) Correct.
2) The y-intercept is when x=0, so it is (0,5).
