Hi,
That would be a circle because it has 360 degrees.
The answer is b this is because you add the angles
Answer:
The ages of people entering a pie eating contest are normally distributed with a mean of 35 years and a standard deviation of 8.2 years.
What is the age of a pie eating contestant with a z-score of −2.1 ?
[ Age - 35 ] / [ 8.2] = -2.1 multiply both sides by 8.2
Age - 35 = -17.22 add 35 to both sides
Age ≈ 17.8 years
I am doing the test right now !!! ;P
ANSWER:
m∠1 = 60°
m∠2 = 60°
m∠3= 120°
EXPLANATION:
The purple arrows indicate that side are parallel, so we know that that triangle NMP is the same as triangle NOP. If they are they same then we know that ∠1 and ∠2 equal 60° since the opposing angles equal 60°.
For ∠3 we look at the opposing angle and now know it is 60°. Since ∠3 and the opposing angle make a straight line which equals 180°. We can figure out ∠3 by subtracting 60 from 180 = 120°.
