Answer:
D. 100
Step-by-step explanation:
1. Find the z-score: 165-176/11.4 = -1.2
2. Find the percentage of the z-score. Here it's 16.85%
3. Because we are searching for the amount of members that weigh MORE than 165 pounds and not LESS, we need to find the greater percentage by subtracting 16.85% from 100% which is 83.15%. This is the percentage of people that weigh more than 165 pounds.
4. Multiply the percentage by the number of members: 83.15%*120 = 99.78
5. Round it to a whole number because someone can't be 0.78 of a person. You get 100 members.
Also, I took the test :)
Y=2
the x axis value didn’t change , only the y value did
if it was a simple y axis reflection, the -4 would become a positive 4, but it didn’t
so the only option is y=2
First, note that x+21 and 3x+9 are "complementary angles;" they add up to 90 degrees. Thus, 4x + 30 = 90 degrees, so that 4x = 60 degrees, and x = 15 degrees.
