A 180° rotation just means to switch the signs of x and y and then swap them.
So if you have (3,5) it would become (-5,-3)
Answer:
47.5%
Step-by-step explanation:
Find the z-scores:
z = (x − μ) / σ
z₁ = (300 − 400) / 50 = -2
z₂ = (400 − 400) / 50 = 0
300 is 2 standard deviations below the mean, and 400 is 0 standard deviations from the mean.
From the empirical rule, 95% of a normal distribution is between -2 and +2 standard deviations. Since normal distributions are symmetrical, that means half of that is between -2 and 0 standard deviations.
95% / 2 = 47.5%
2y=29+3
2y=32
Y=32/2
Y=16
Hope that is right
Answer:

rounded to the nearest hundredth
Step-by-step explanation:
use the pythagorean theorem to find the height of the cone

you get a = 8
the formula for the volume of a cone is

plug in 6 for the radius and 8 for the height. then solve
