Answer:

1. 18

2. 49.5

3. 48

Step-by-step explanation:

1. Since it is 3 dogs to 1 person we need to multiply 6 with 3, so we get 18 dogs!

2. Since 2 books equal 8.25, we just need to multiply 8.25 by 6, which we get 49.5 from!

Hope this helps and don't forget to follow!

About 6% of the population has a particular genetic mutation. 600 people are randomly selected. find the standard deviation for
Rina8888 [55]

Assume a binomial distribution. Then the mean of the distribution is np, where n is the number of people taken in a sample and p is the probability of the mutation occurring in any given person, and the standard deviation is \sqrt{np(1-p)}. Then in this case, the standard deviation is \sqrt{600(0.06)(0.94)}\approx5.82.

Evaluate the indefinite integral. (Use C for the constant of integration.) sin(10x) 1 cos2(10x) dx
Schach [20]

Answer:

The result of the integral is -\frac{\cos^3{10x}}{30} + C

Step-by-step explanation:

We are given the following integral:

\int \sin{(10x)}\cos^{2}{(10x)} dx

I am going to solve by substitution, using u = \cos{10x}, so du = -10\sin{10x}dx, dx = -\frac{du}{10\sin{10x}}. So, we have

-\frac{1}{10} \int u^2 du

Which has the following result:

-\frac{u^3}{30} + C

Going back to x, the result of the integral is

-\frac{\cos^3{10x}}{30} + C

Can somebody tell me the answer and maybe tell me how you got it too.​
asambeis [7]

To get t on one side, we have to use inverse operations to get rid of the 5.

1. Use inverse operation of multiplication to get rid of 5. Which would be division.

2. Divide both sides by 5.

5t/5 = 7 1/2 / 5

3. Solve.

5t/5 = t and 7 1/2 /5 = 1 1/2

7.5 / 5 = 1.5

Therefore, your answer would be C. divide both sides by 5, and the answer is 1 1/2.
