Answer:
S/2πr-r = h
Step-by-step explanation:
S = 2πr(h + r)
S/2πr = h+r
S/2πr - r = h
Answer:
C) 88
Step-by-step explanation:
so we are given a circle, and m<ACB is 44°. We need to find the measure of arc AB
<ACB is an inscribed angle (it is inside the circle), and it intercepts the arc AB
Inscribed angle theorem is a theorem that states the measure of an inscribed angle is half of the measure of the arc it intercepts
which also means that the measure of the intercepted arc is twice the measure of the inscribed angle (this is because of how algebra works)
which means mAB=2m<ACB (inscribed angle theorem)
mAB=2*44° (substitution)
mAB=88° (algebra)
therefore, your answer is C
Hope this helps!
Answer:
e. 11.11
Step-by-step explanation:
We use the negative binomial distribution to solve this question.
The mean of the negative binomial distribution is the average number of trials required to produce r sucesses, with p probability. Mathematically, this is described by the following formula:
In this problem, we have that:
Approximately 9 percent of the residents of a large city have seen a certain theater production that is currently playing in the city. This means that
What is the expected number of residents the researcher will need to ask to find someone who has seen the production?
This is when r = 1. So
So the correct answer is:
e. 11.11
8 x 5 = 40
40 hours = 2400 minutes
2400>2250
