the answer to this question is -7.25 or 7 1/4
To work out the mean, add them all up and divide by however many values there are:
(18+54+42+(76x2)+46) / 6 = 52
To work out the median, order them from largest to smallest or vice versa and find the middlest value.
18, 42, 46, 54, 76 ,76
(46 + 54) / 2 = 50
The mode is the most frequently occurring number, so it would be 76.

Answer:
1.495
Step-by-step explanation:
You can see that the base is 5 units.
The height is 3.
The area of a parallelogram is
A = B * H
A = 5 * 3
A = 15 units^2
Hope this helps!
Answer:
.
Step-by-step explanation:
I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y =
. The shaded region in blue is the region we are going to rotate.
Now, to find the volume v=
where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)=
. Then,
v = 
= 
= 
= 
= 
=
.
