a bag of candy contains red lollipops and purple lollipops. 80% of the lollipops in the bag are red. a number generator simulates selecting 10 lollipops from the bag. the number generator is used 10 times and the number or red candy in each simulated trial is shown in the dot plot.

which description is correct about the number generator?
question 2 options:

the number generator is not fair. in 3 experiments, it picked red lollipops 90% of the time.

the number generator is not fair. the correct percentage of red lollipops was not chosen at all.

the number generator is fair. it picked red lollipops half of the time.

the number generator is fair. it picked the approximate percentage of red lollipops most of the time.

The number generator is fair. it picked the approximate percentage of red lollipops most of the time. I just took this test and made a 100 I hope this helps!!!

The correct answer is D) The number generator is fair. It picked the approximate percentage of red lollipops most of the time.

Step-by-step explanation:

We can tell this because the average of red lollipops in the trial is 8. This gives us a 80% average.

7 + 7 + 7 + 8 + 8 + 8 + 8 + 9 + 9 + 9 = 80

80/10 = 8

8/10 = 80%

4+4+2x

or

2x+8

step-by-step explanation:

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
