Answer:
The formula to find the nth term of the given sequence is 54 ·
Step-by-step explanation:
The formula for nth term of an geometric progression is :
In this example, we have = 36 (the first term in the sequence) and
r = (the rate in which the sequence is changing).
Knowing what the values for r and are, now we can solve.
=
= 54 ·
Therefore, the formula to find the nth term of the given sequence is
54 ·
Answer:
Probability that the proportion in our sample of red candies will be less than 20% is 0.5 .
Step-by-step explanation:
We are given that 20% of the candy produced are red. A random sample of 100 bags of Skittles is taken.
The distribution we can use here is;
~ N(0,1)
where, p = 0.20 and n = 100
Let = proportion of red candies in our sample
So, P( < 0.20) = P(
<
) = P(Z < 0) = 0.5
Therefore, probability that the proportion in our sample of red candies will be less than 20% is 0.5 .
