Out of all the numbers from 1 to 80, there are (80-20)/(80) = 60/80 = 0.75
of them that are greater than 20 .
So every time you pick one at random, there a 75% chance that it will be
greater than 20.
If everything works out according to pefectly random probabilities, then
in 180 selections, 75% of them = (0.75 x 180) = <em>135 of the selections</em>
would be numbers greater than 20 .
For this one, look at the symbols inside each angle. In math, the rounded edges inside of angles mean they are congruent. So find which ones have the same amount of rounded edges and that would be your answer.
NKW ≅ UZE
put the corresponding angles in the middle. Since the object you were comparing to had the one line as the middle point, then that is your middle as well.
Hope this helps! Comment with any questions you may have.
Answer:
Step-by-step explanation:
I think you are inventing symbols, which turns your question into a guessing game. You are better off describing the math symbols in words. Or post a picture.
I’m guessing that the math expression is ∛27 + √64² - 2 = 3 + 64 - 2 = 65
31 to the zero power is 1, anything but zero to the power of zero is 1. Zero to the power of zero is undefined. Hope that helps
Answer:
e = sqrt(f - h) or e = -sqrt(f - h)
Step-by-step explanation:
If e^2 = f - h, then you just need to square root both sides.
The squared and square root cancel out on e, and f - h can just be put into a square root.
