These are linear equations, so there is x and y. On number one the first thing they plotted was (3,8) so in a function table the 3 would be on the left side and the 8 would be on the right side. I’ll leave you with the rule of the first one, if the rule is times 2 plus to the how would you put it in a function table.

The first thing that you would put into the function table on the first question would be as I said earlier 3 and then 8. The rule is the rate. Using a function table will be very helpful (That’s why I keep mentioning one). Let me know if this helps.

Find x to the nearest tenth

Sphinxa [80]

<h3>Answer: x = 14.3</h3>

=========================================================

Explanation:

We can find x using the law of sines, but first we need to find the missing angle. Let's call that y for now. The three angles of any triangle add to 180, so,

23+146+y = 180

169+y = 180

y = 180-169

y = 11

The missing interior angle is 11 degrees.

-----------

Now we can apply the law of sines.

sin(23)/x = sin(11)/7

7*sin(23) = x*sin(11)

x*sin(11) = 7*sin(23)

x = 7*sin(23)/sin(11)

x = 14.3343236728824

x = 14.3

Make sure your calculator is in degree mode.

A teacher needs to find out how many seventh-grade students will be going on a field trip. Which best describes the population t

kherson [118]

Answer:

In statistics , the population is the set of all possible observations as per the researcher's objective .

For example if a researcher wants to find the average height of teenager of age group between 13 year and 15 years in Seattle, he will need the data of the population of height of teenager of age group between 13 year and 15 years in Seattle.

Here , A teacher needs to find out how many seventh graders will be going on a field trip.

Clearly as per her objective she need the data of all seventh graders .

So , the best describes the population that the teacher should survey would be : All seventh graders.
