balandron [24]

Answer:

Mean: 3 Mad: 1/3

Step-by-step explanation:

First we need to find out the numbers, so to get a mean of 3 we have to get to 9 ebcause there are 3 arrows.

  • We have to make sure that the arrows are not too close to the center
  • You can have decimals

2nd: Once you find the numbers which are 2.5, 3, and 3.5 you add them together and divide it by 3 to get 3 the mean

3rd: Find the MAD but adding .5 and .5 to get 1 then divide it by 3 and you get 1/3 as the MAD.

Hope this helps!

What is the equation of a line through the point (2,3) and is parallel to y=4x-1
Iteru [2.4K]

Answer:

The equation of this line would be y = 4x - 5

Step-by-step explanation:

In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is 4, which means the new slope will also be 4 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.

y - y1 = m(x - x1)

y - 3 = 4(x - 2)

y - 3 = 4x - 8

y = 4x - 5
