Answer:
Step-by-step explanation:
arithmetic sequence: 60,68,76,......
a = 60
d = 68 - 60 = 8
an = a + (n-1)*d
a20 = 60 + 19 * 8
= 60 + 152
= 112
There are 112 seats in the 20th row
This answer is 200 because 64x100/32
Answer:
The probability is;
0.0000003645
Step-by-step explanation:
The probability of packages being early p is 90% = 0.9
The probability of packages being late q will be 1-p = 1-0.9 = 0.1
So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem
That will be;
P(X = 2) = 10 C 2 0.9^2 0.1^8
= 0.0000003645
Wheres the rest of the question, or is that it?
