An ice cream factory makes 330 quarts of ice cream in 5 hours. How many quarts could be made in 12 hours?

1 answer:

3 0

First find how many quarts are made per hour.

To do this, divide 330 quarts by 5 hours:
$330 \div 5$
This gives you 66 quarts per hour.

Multiply this by 12 to find out how much is made in 12 hours.
$66 \times 12$
Answer: 792 quarts

-3(2t-1)=t+t+t+3 pls help

LuckyWell [14K]

Answer:

t=0

Step-by-step explanation:

First, we expand everything. The left-hand side is -3(2t) - 1(-3), and we expand it to be -6t+3. The right-hand side is t+t+t+3, and we can reduce it to 3t+3. Now that we have both sides of the equation, we set them to each other.

-6t+3=3t+3 (subtract 3 on both sides)
-6t=3t (add 6t to both sides)
9t =0 (divide by 9)
t=0

It has been conjecture by the U.S. Census Bureau that "approximately 60% of foreign-born people who live in the U.S. are not nat

Answer:

b. 42 people

Step-by-step explanation:

For each foreigner living in the U.S., there are only two possible outcomes. Either they are naturalized citizens, or they are not. The probability of a foreigner living in the U.S. not being a naturalized citizen is independent from other foreigners living in the U.S. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

"approximately 60% of foreign-born people who live in the U.S. are not naturalized citizens"

This means that $p = 0.6$

70 foreign-born people who live in the U.S

This means that $n = 70$

How many people would you expect to get that are not naturalized citizens?

$E(X) = np = 70*0.6 = 42$

So the correct answer is:

b. 42 people

Please help me. if I don’t complete my course I’m getting sent back to my parents house, and I need to complete this course

Doss [256]

For the first question, yes, they are similar. Each of the corresponding sides has a ratio of 4:1 from the first polygon to the second, meaning they are similar. For the second question, the ratio is 1.6:1, and if we multiply the 10 on the bottom polygon by 1.6, we get 16, which is the answer.

For real though, I’m hoping you don’t get sent back there. I’m assuming you dislike it there, so good luck with your course. I’m here to help if you need it.
