Answer: Yes, This sample provide evidence that the length of time for baseball games is more than 170 minutes.
Step-by-step explanation:
Since we have given that
Mean length of the games = 179.83
Standard error = 3.75
We need to find the value of P(X>170).
So, it becomes,
Let
Since z is greater than z(critical value).
So,Yes, This sample provide evidence that the length of time for baseball games is more than 170 minutes.
y = 25 + 0.15x is the equation for relating the cost y to the number of miles x that you drive the car
<em><u>Solution:</u></em>
Let "y" be the total cost of car rental
Let "x" be the number of miles you drive the car for more than 100 miles
<em><u>A car rental firm has the following charges for a certain type of car:</u></em>
$25 per day with 100 free miles included, $0.15 per mile for more than 100 miles
<em><u>Suppose you want to rent a car for one day, and you know you'll use it for more than 100 miles</u></em>
Therefore,
Car is rented for one day
You will use it for more than 100 miles
Therefore, equation is framed as:
Total cost = $ 25 + 0.15(number of hours)
Thus the equation for relating the cost y to the number of miles x that you drive the car
