What is the median of the data set?
gizmo_the_mogwai [7]
7. because you would put the number set into order from least to greatest first, ti would look like this: 2,3,4,5,9,10,12,12. then go to the middle, crossing one from each side off at one time. Then you get 5 and 9 in the middle. Then the middle between 5 and 9 is seven, you can check this by: 5+9=14, then 14/2= 7.

Write an equation of the line that has a slope of 5 and goes through the point (3,3)
professor190 [17]

Answer:

y=5x-12

Step-by-step explanation:

The general equation of a line is <em>y=mx+b</em>.

The equation you currently have is <em>y=5x+b</em>.

Plug in the point (3,3) which will get you <em>3=5(3)+b</em>.

Solve the equation by solving what the y-intercept (b) is to create the new final equation.

3=5(3)+b

3=15+b

b=3-15

b=-12

y=5x-12

Practice solving quadratic equations.
Dennis_Churaev [7]
In order for the equation to be true, one of the factors on the left has to equal zero

So, 2x-3=0 or x-4=0 (the 3 on the left for multiplication doesn’t affect the possible answers for x)

Once you solve them, you conclude that x has to be 4 or 3/2.
