Answer:
150 people
Step-by-step explanation:
First, look over the chart and find the rows that have listed as 26 - 30 and 31 - 35.
Find out how high the row goes by looking at the number on the side of the gram.
26 - 30 goes to 60
31 - 35 goes to 90
Then add the 2 numbers together and you will find your total
60 + 90 = 150 people
Answer:
Depends, rise over run could be considered a fraction, or if it's a number that has a whole number like one and 3/4 then you just plot the point to the best of your ability. In other words guess.
I've attached a plot of one such cross-section (orange) over the region in the x-y plane (blue), including the bounding curves (red). (I've set

for this example.)
The length of each cross section (the side lying in the base) has length determined by the horizontal distance

between the y-axis

and the curve

. In terms of

, this distance is

. The height of each cross section is twice the value of

, so the area of each rectangular cross section should be

.
This means the volume would be given by the integral
You can use the prefixes to figure this out:
Mono: one
Bi: two
Tri: three
So, because there is only one term, it is a monomial.
