Jamar has a bag that contains apple chews, lemon chews, and peach chews. He performs an experiment. Jamar randomly removes a chew from the bag, records the result, and returns the chew to the bag. Jamar performs the experiment 59 times. The results are shown below: An apple chew was selected 53 times. A lemon chew was selected 3 times. A peach chew was selected 3 times. Based on these results, express the probability that the next chew Jamar removes from the bag will be apple chew as a decimal to the nearest hundredth.

Answers

Answer:

the answer is 0.90

Step-by-step explanation:

Answer:

The probability that the next chew Jamar removes from the bag will be an apple chew is:

P(apple) = number of times an apple chew was selected / total number of experiments

P(apple) = 53 / 59

P(apple) ≈ 0.90

Rounded to the nearest hundredth, the probability that the next chew Jamar removes from the bag will be an apple chew is 0.90.

The data about the number of minutes per day is so confusing. I'll just answer it based on what I understood from the data provided:

Monday: 480 minutes
Tuesday: 450 minutes
Wednesday: 495 minutes
Thursday: 480 minutes
Friday: 300 minutes

We need to add up all the minutes worked for the week:
480 + 450 + 495 + 480 + 300 = 2,205 minutes

2,205 minutes / 60 minutes = 36.75 hours

36.75 hours is less than the maximum number of hours worked in a week which is 40 hours.

36.75 hours translates to 36 hours and 45 minutes of work for the week.

How to solve x + 2y = 134x + 8y = −9
I get confused after eliminating the x.
Please help?

Answers

You need to multiply x + 2y = 13 by -4 then the -4 and +4 will cancel each other out then you solve the rest of the equation.

y= zero

using the process of substitution I had this...

4( -2y +13) +8y = -9
distribution -8y +52 -8y= -9

so -8y+8y =0
you end up having zero for y no matter what the subtraction of 52 was, because anything divided by zero is zero...

so if you already have the x value, your point is going to be an x-intercept
