Hiii I think that she wrode her bike 18 miles in one hour because 3 times 5 equals 15 miles and 15 miles equals 50 minutes. So if you add another 3 miles to 15 you get 18 miles in one hour

A candy company claims that 20% of the candies in its bags are colored green. Steve buys 30 bags of 30 candies, randomly selects
Allisa [31]

Answer:

The probability of Steve agreeing with the company’s claim is 0.50502.

Step-by-step explanation:

Let <em>X</em> denote the number of green candies.

The probability of green candies is, <em>p</em> = 0.20.

Steve buys 30 bags of 30 candies, randomly selects one candy from each, and counts the number of green candies.

So, <em>n</em> = 30 candies are randomly selected.

All the candies are independent of each other.

The random variable <em>X</em> follows a binomial distribution with parameter <em>n</em> = 30 and <em>p</em> = 0.20.

It is provided that if there are 5, 6, or 7 green candies, Steve will conclude that the company’s claim is correct.

Compute the probability of 5, 6 and 7 green candies as follows:

P(X=5)={30\choose 5}(0.20)^{5}(1-0.20)^{30-5}=0.17228\\\\P(X=6)={30\choose 6}(0.20)^{6}(1-0.20)^{30-6}=0.17946\\\\P(X=7)={30\choose 7}(0.20)^{7}(1-0.20)^{30-7}=0.15328

Then the probability of Steve agreeing with the company’s claim is:

P (Accepting the claim) = P (X = 5) + P (X = 6) + P (X = 7)

                                       = 0.17228 + 0.17946 + 0.15328

                                       = 0.50502

Thus, the probability of Steve agreeing with the company’s claim is 0.50502.

If there 10% of a 60ml bottle is filled with antifreeze, how much antifreeze (ml) was in the bottle? If 50% of a 20ml bottle is
miss Akunina [59]

Answer:

Part A: 6ml of antifreeze

Part B: 10ml of antifreeze

Step-by-step explanation:

10% of 60ml is 6ml

60/10 = 6

1/10 of 60 equals 6ml.

50% of 20ml is 10ml.

20/2 = 10

1/2 of 20 equals 10ml.
