Use Y=-2/3x + b
and then plug in (-7,-4)
-7 is x, so plug that in for x
Y=-2/3(-7) + b
and plug in y, -4
-4=-2/3(-7) +b
plug into calculator and then solve algebraically!
b doesn’t mean anything, it’s just what i used for the y axis, really you could use any letter
Answer:
x = 4 y=540
Step-by-step explanation:
the x is going up by 4
the y is going up by 180
The data are bunched towards the higher values above the mean, but spread out to values below the mean. Therefore the median provides a better description of the center.
This is a question of probability.
Probability of picking any color= number of tiles with that color/total number of tiles
Total=45+25+30=100
P(red tile)=(45/100)x60=0.45x60=27
P(blue tile)=(25/100)x60=0.25x60=15
P(green tiles)=(30/100)x60=0.3x60=18
