Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 37 times. The results are shown below:

A strawberry chew was selected 8 times.

A cherry chew was selected 12 times.

A watermelon chew was selected 17 times.


Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a decimal to the nearest hundredth.

Answers

Answer:

32.43%

Step-by-step explanation:

Since there are a total of 37 tests and cherry was selected 12 times, the probability would be 12/37.

12(100/37)

32.43

The probability that it will be a cherry or watermelon is; P(Cherry or water melon) = (12 + 17)/37 = 0.51

How to find the Probability?

We are told that Ryan performs the experiment a total of 37 times.

From the experiment he got;

Strawberry = 8 times

Cherry = 12 times

Watermelon = 17 times

Thus, probability that it will be a cherry or watermelon is;

P(Cherry or water melon) = (12 + 17)/37 = 0.51

Rewrite each equation without using absolute value for the given conditions. y=|x−3|+|x+2|−|x−5|, if x>5

Step-by-step explanation:

If x >5     then    |x-3|   is just  x-3

                        |x+2|    is just   x + 2

A truck drove 208 miles on 5 gallons of gas. How far should it be able to go on a full, 11-gallon tank?

Answers

Answer:

457.6

Step-by-step explanation:

if he drove 208 on 5 gallons, 208/5 =41.6 miles per gallon. 41.6*11= 457.6

Answer:

457.6 miles

Step-by-step explanation:

So 208 miles equals 5 gallons so if you add 208 two times you will already have used 10 gallons and that equals 416 miles so far. So now you have to divide 208 by 5 and that equals 41.6 so 416 plus 41.6 equals 457.6 miles

A​ 12-sided solid has faces numbered 1 to 12. The table shows the results of rolling the solid 200 times. Find the experimental probability of rolling a number less than 3 .

Answers

Answer:

3/20 or 0.15 or 15%

Step-by-step explanation:

The experimental probability is

amount of wanted outcomes/total amount of outcomes

Less than 3 is 1 and 2.

1= 14 times

2= 16 times.

Add, get 30.

30 is the amount of wanted outcomes, and the total is 200.

30/200 is either 3/20, 0.15, or 15%, because of different formats.

After 5 years, $40,000 deposited in a savings account with simple interest had earned $26,000 in interest. What was the interest rate?

Answers

Answer: The answer is 13% interest rate.

Step-by-step explanation: first divide the interest money by the number of years (or months it doesn't matter) which would get you 5200 then you would divide 5200 by the amount of money deposited into the bank (40,000) which should give you 0.13 or 13%

26,000 / 5 = 5,200

5,200 / 40,000 = 0.13 = 13%
