Answer:

1.

25 of the 36 collars will be accepted. I just counted the numbers that were either "14" "15" or "16" because the company will only accept the collars that have 14-16 miligrams of medicine in them.

2. I expect the company to reject 11 of them because 25-36 = 11

Answer:

Step-by-step explanation:

Okayy, so we know that the domain for the flea collars (let's call them x for short) is:

14\leq x\leq 16

So basically we can eliminate all of the numbers that don't fit the inequality

In this set of numbers we are looking to eliminate the 13's and the 17's

17, 14, 14, 16, 14, 15, 15, 15, 16, 14, 16, 14, 15, 15, 15, 16, 13, 13

13, 13, 13, 14, 14, 13, 17, 14, 15, 13, 14, 15, 16, 17, 14, 17, 14, 15

The bolded ones are the ones to eliminate, also that took way too long to type those :,)

Now here's what's left:

14, 14, 16, 14, 15, 15, 15, 16, 14, 16, 14, 15, 15, 15, 16

14, 14, 14, 15, 14, 15, 16, 14, 14, 15

Now we can answer the questions

A) What percent of collars would be acceptable?

To find this answer we must find the percent of collars that are left out of all of the collars we used to have

(I hope that makes somewhat sense)

To find this we need to know the number of collars we started with and the number of collars we have left

We started with 36

We have 25 left

25/36 is about

69.44 percent

This number works even though we only used 36 because the ratio of good collars to be bad collars should be consistent throughout the whole 720 collars

A car used 15 gallons of gasoline and traveled a total distance of 350 miles. The car's fuel efficiency is 25 miles per gallon o
stepan [7]
The equation would be letter b. 25h + 20 (15 - h) = 350
Let’s try to solve to get the value of h
=> 25h + 20(15 -h) = 350
=> 25h + (300 – 20h) = 350
=> 25h + 300 – 20h = 350
=> 300 + 5h = 350
=> 5h = 350 – 300
=> 5h / 5 = 50/ 5
=> h = 10
Thus the value of h is 10 which means a car travel on the highways and used 10 gallons of gasoline,
