A farmer applied different types of fertilizer to two different sections of his watermelon field. At the end of the growing seas
Softa [21]
The mean is the average weight.
 the MAD is how spread out the weights are from the mean, the higher the number the more spread out, which means you could have more lower weights than higher weights, of more heavy than light

 so fertilizer 1 had a higher average weight ( 24 is greater than 22)
 and the difference in MAD is only 1 ( 3-2)

so the farmer CAN conclude , because the distribution is SOMEWHAT SIMILAR

HELP............Graph. y+1=1/3(x−3) (it has to have 2 points)
natta225 [31]
The intercept method of graphing is quick and easy.

Find the x-intercept by setting y = 0 and solving for x:

y+1=1/3(x−3)   =>   0<span>+1=1/3(x−3)
  Multiply both sides by 3:  3 = x - 3.  Then x = 6, and the x-int. is (6, 0).

Find the y-int by setting x = 0 and solving for y:

</span><span>y+1=1/3(0−3)
Mult both sides by 3:  3y+3 = -3, so that 3y = -6, and y = -2.
Then the y-intercept is (0,-2).

Plot these 2 points.  Then draw a line thru them.</span>
