The scientist would use milligrams, grams, and kilograms.
The best procedure would be to randomly pick 52 fish from the entire pond and weigh each of them as this would be the most unbiased way to achieve the average mass
Hi there!

Find the midpoint using the midpoint formula:
m = (p1 + p2) / 2
m = (-2 + 12) / 2
m = 10 / 2
m = 5.
Hi there.
All we have to do to find out how many people like the plan is multiplication.
We multiply the total number of people by 60% - in decimal form.
600 · 0.6 = 360
360 people liked the plan.
-10 is less than -5 because negative numbers are farther from 0. Same applies to -4 and -20.
The answer would be 2x^2+2x-24
using foil, you would multiply together x & x, x & 6, -4 & x, and -4 & 6, then add them together.
