Sorry, I did them out of order because I started doing the second problem first on accident.

For the second question: the probability that you choose a green marble is 2/(2 + 3 + 3) = 2/8 = 1/4. The probability that you choose a red marble without replacing the green one is: 3/(2 + 3 + 3 - 1) = 3/7. Now, multiply these two fractions together because they depend on each other:

1/4 * 3/7 = 3/28

For the first question: the probability you choose a green marble is still 1/4. The probability that you choose a yellow marble is 3/(2 + 3 + 3 - 1) = 3/7. Multiply these two fractions together and you get: 1/4 * 3/7 = 3/28 again.

The answer to both questions is 3/28.

Answer:

0.6210

Step-by-step explanation:

Given that a Food Marketing Institute found that 39% of households spend more than $125 a week on groceries

Sample size n =87

Sample proportion will follow a normal distribution with p =0.39

and standard error = $\sqrt{\frac{0.39(1-0.39)}{87} } \\=0.0523$

the probability that the sample proportion of households spending more than $125 a week is between 0.29 and 0.41

= $P(0.29$

There is 0.6210 probability that the sample proportion of households spending more than $125 a week is between 0.29 and 0.41

F - Irrational, -13.8
Because the negative sign is not inside of the radical, we can tell that the number is being multiplied by the negative. Thus, do the radical equation first, get the answer 13.8202... and multiply by -1 to get the answer. Also, it is irrational because it is not a perfect square.
