Answer:
a. 7 ft
Step-by-step explanation:

16 or more books sold in a day will include two intervals from the given table:
a) 16 - 20 books sold.
Probability = 0.201
b) 21 - 25 books sold.
Probability = ?
Since the table gives the probability distribution, the sum of all the probabilities must be equal to 1. We are given the probabilities of 4 out 5 intervals. So in order to find the probability of the 5th interval (21-25) we can subtract the sum of probabilities of rest of the intervals from 1.
So, P(21 - 25) = 0.019
In order to find the probability of 16 or more books sold we need to sum the probabilities of both these intervals.
So, the probability of 16 or more books being sold on a given day = 0.201 + 0.019 = 0.220
Answer:
9 hours
Step-by-step explanation:
If he earns 12.50 an hour...
112.50 ÷ 12.50 = 9 hours
Given
Michonne's Phone service charges $18.09 for an activation fee plus $2 for every gigabyte(g) used
Show the graph model for the above sitution.
To proof
As given in the question
Michonne's Phone service charges = $18.09
activation fee plus for every gigabyte(g) used = $2
let the gigabyte used be = x
let the total charges of phone = y
Than the equation become in the form
18.09 + 2x =y
the graph is shown as below.
Hence proved
Answer:
12
Step-by-step explanation:
6x2=12 (do the parentheses first) and 12 times 1 is 12
