Answer:

The given table represents a function f(x) = y = 2x+3

The upper graph

Step-by-step explanation:

We will write the equation of the right line in the explicit (slope) form

y = ax+b

We will take two points from the given table

A(-1,1) and B(0,3) and insert their coordinates in the equation y=ax+b and get

A(-1,1) => 1 = (-1)*a+b => -a+b=1

B(0,3) => 3=0*a+b => 3= 0+b => b=3

Now we will insert b=3 in the equation -a+b=1 and get

-a+3=1 => a=3-1 => a=2

Now we will insert a=2 and b=3 in the equation y=ax+b and get

equation of the function

y = 2x+3 = f(x) The upper graph.

Good luck!!!

Ilya [14]

Answer:

The value of the test statistic and degrees of freedom is 2.148 and 11 respectively.

Step-by-step explanation:

Consider the provided information.

The mean annual tuition and fees for a sample of 12 private colleges was 36,800 with a standard deviation of 5,000 .

Thus, n = 12, $\bar x=36800$ σ = 5000

degrees of freedom = n-1 = 12-1 = 11

$H_0: \mu = 33700\ and\ H_a: \mu \neq 33700$

Formula to find the value of z is: $z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}$

Where $\bar x$ is mean of sample, μ is the mean of population, σ is the standard deviation of population and n is number of observations.

$z=\frac{36800-33700}{\frac{5000}{\sqrt{12}}}$

$z=2.148$

Hence, the value of the test statistic and degrees of freedom is 2.148 and 11 respectively.

Please help?? its unit rate so plz help tell me how to do it

Lelechka [254]

Answer:

1.2 dollars

Step-by-step explanation:

You have to divide the dollar count by the pound count.

So basically:

6/5

This gives you 1.2 dollars.

When you do unit rate, you just have to divide one value by the other value.

The value you divide by, and the value you divde, vary depending on what the question asks.

For instance, if this question asked what the pound count for 1 dollar would be, you would end up divide the 5 pounds by 6 dollars(5/6) instead of divideing the 6 dollars by 5 pounds like we did above(6/5).

Hope this helps!
