You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. You asked 15 people to pull a random marble and replace it. Th

e outcome was that 10 got red, 4 got blue and 1 got green. Joe thinks if 15 more people try 8 will pull red. Jill thinks if 15 more people try 10 will pull red. Choose the most accurate statement.
a
Joe is right because the theoretical probability is better.
b
Jill is right because the experimental probability is better.
c
We don't know what will happen, but both Joe and Jane are making good, educated assumptions.
d
We don't know what will happen because anything is possible and there is not point in calculating probabilities. Whatever happens, happens.
e
6 people will pull red to average out to 8. The long term average must match the theoretical probability.

Answer:

C.

Step-by-step explanation:

We have 2 probabilities: Theoretical probability and Experimental probability.

We cant know what will happen as it's just probability but both joe and Jill are making educated guesses based on probabilities, just different kinds.

Determine whether the given sequence could be geometric, arithmetic, or neither. if possible, identify either the common ratio o
REY [17]

ARITHMETIC CHECK: A sequence is said to be arithmetic if any two consecutive terms differ by the same constant.

So, the test to check if a series is arithmetic is to compute consecutive differences, and see if they all return the same number.

If we subtract the first two terms, we have 2-4 = -2. If we subtract the third and second terms, we have 1-2 = -1.

These two differences returned two different values, so the series is not arithmetic.

GEOMETRIC CHECK: A sequence is said to be geometric if any two consecutive terms are in the same ratio.

So, the test to check if a series is geometric is to compute consecutive ratios, and see if they all return the same number.

If we divide the first two terms, we have

\dfrac{2}{4} = \dfrac{1}{2}

If we divide the third and second terms, we have

\dfrac{1}{2} = \dfrac{1}{2}

Finally, if we divide the last two terms we have

\dfrac{\frac{1}{2}}{1} = \dfrac{1}{2}

So, all ratios return the same number. This means that the series is geometric, and the common ratio is 1/2
