Determine the explicit formula for the table
First, we need to check if the guppies increases at arithmetic progression or geometry progression.
For arithmetic progression:
We calculate the common difference (d)
Take n as 1
From the table:
Take n as 2
From the table:
The two differences are not equal. So, this
For geometry progression:
We calculate the common ratio (r)
Take n as 1
From the table:
Take n as 2
From the table:
The two ratios are equal.
So, the next step is to calculate the explicit formula using n term of a geometric progression.
Because the progression starts from 0, we make use of the following formula
Substitute values for g(0) and r
Hence:
The explicit formula is:
Answer:
The probability of the customer selecting both items is 0.04.
Step-by-step explanation:
The complete question is:
The probability that a customer selects a pizza with mushrooms or pepperoni is 0.45, and the probability that the customer selects only mushrooms is 0.32. If the probability that he or she selects only pepperoni is 0.17, find the probability of the customer selecting both items.
Solution:
The information provided is as follows:
P (M) = 0.32
P (P) = 0.17
P (M ∪ P) = 0.45
Compute the probability of the customer selecting both items as follows:
Thus, the probability of the customer selecting both items is 0.04.
Answer: 0.5

You can make this into an inequality, using x as the number of uniforms.
100 + 12x < 61 + 15x
39 < 3x
13 < x, so they must buy more than 13 to get a better deal.
