Answer:
520<400+15x
15x>120
15x+400>520
Explanation:
Pay of Dan's car wash attendant job =$400 per week
The amount he earns per hour walking dogs = $15
Let the number of hours spent walking dogs in a week = x
Therefore, total earning for walking dogs =$15x
Since he wants to earn more than $520, we have that:
We can rewrite this as:
If we collect like terms, we have:
So the inequalities are:
0. 520<400+15x
,1. 15x>120
,2. 15x+400>520
Answer:
It is more likely that a high school baseball game will last between 100 and 110 minutes or that a high school softball game will last between 100 and 110 minutes
Step-by-step explanation:
We are given the following information in the question:
Basket ball game:
Mean, μ = 105 minutes
Standard Deviation, σ = 11 minutes
Softball game:
Mean, μ = 95 minutes
Standard Deviation, σ = 11 minutes
We are given that the distribution of durations of high school baseball games is a bell shaped distribution that is a normal distribution.
Formula:
P(basketball game will last between 100 and 110 minutes)
P(softball game will last between 100 and 110 minutes)
Since,
P(basketball game) > P(softball game)
It is more likely that a high school baseball game will last between 100 and 110 minutes or that a high school softball game will last between 100 and 110 minutes
