Answer:
C converse of alternate interior angles
Answer:
Step-by-step explanation:
Total Students = 20 + 18 = 38 students
For boys percentage = 20/38 * 100
Boys percentage = 52.6%
For girls percentage = 18/38 * 100
Girls percentage = 47.3%
Answer:
x = -30
Step-by-step explanation:
1) x/2 = 4 - 19
2) x/2 = -15
3) x = -15*2
4) x = -30
Answer:
0.9999
Step-by-step explanation:
Let X be the random variable that measures the time that a switch will survive.
If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by
So, the probability that a switch fails in the first year is
Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.
Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and
where
equals combinations of 100 taken k at a time.
The probability that at most 15 fail during the first year is
