Answer:

5p + 7q

Step-by-step explanation:

7p + 6q - 2p + q

All you need to do is....

Combine Like Terms

* Put all the ones with "p"'s together, and all the ones with "q"'s together

7p with -2p and 6q with q

7p - 2p + 6q + q

5p + 7q

And you cannot simplify it anymore, because they are not like terms (dont have the same variables)

Hope this helped!

A study was conducted in order to estimate μ, the mean number of weekly hours that U.S. adults use computers at home. Suppose a

777dan777 [17]

Answer:

The point estimate for $\mu$ is 8.5 hours.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .

In this problem

We are working with a sample of 81 adults, so the point estimae of the mean is the mean number of weekly hours that U.S. adults use computers at home.

So, the point estimate for $\mu$ is 8.5 hours.

an architect wants to build three similar triangles such that the ratio of the middle triangle. The smallest one has side length

vampirchik [111]

Answer: 15

<u>Step-by-step explanation:</u>

small: 5 12 13

middle: __ 36 39

large: 45 108 117

Notice that to get from the small to the large, multiplied by 9

5(9) = 45 12(9) = 108 13(9) = 117

That is because the sides are proportional $\dfrac{5}{45}=\dfrac{12}{108}=\dfrac{13}{117}\rightarrow\dfrac{1}{9}$

To get from small to middle, multiply by 3

5(3) = 15 12(3) = 36 13(3) = 39

To solve it using proportions:

$\dfrac{5}{x}=\dfrac{12}{36}\\\\\\\text{Cross Multiply and solve for x:}\\5(36)=12x\\\\\dfrac{5(36)}{12}=x\\\\5(3)=x\\\\\large\boxed{15}=x$

What is the domain and range

Rainbow [258]

Well, keep in mind that the domain of a function is the entire set of possible values of the independent variable. To make it more clear, the domain is the set of all possible x-values, which will make the function work, and with real y-values as the output. So, the range would be the set of all of the second elements of an ordered pair (y-coordinates).

If you made a T chart like the picture you have above, you would have to put x (age of person) and y (books read).

So,

x = age of person

y = books read
