The outlier is the number that’s farther away from the others, in this case it’s 9. The mean is the average of all the data points so it is 77/20 or 3.85. Finally, the range is the highest number minus the lowest number, so the range is 8.
Remember you can do anything to an equation as long as you do it to both sides
and when multiply by negative, flip sign
8+h>2+3h
minus h both sides
8+h-h>2+3h-h
8+0>2+2h
8>2+2h
minus 2 both sides
8-2>2-2+2h
6>0+2h
6>2h
divide by 2 both sides
6/2>2h/2
3>1h
3>h
first opotin
Step-by-step explanation:
The coefficient of the x term repesents the slope of the graph.
So we have y = 2x +- ( ).
We have to find our number term, so let's substitute x = 4 and y = 3.
(3) = 2(4) +- ( )
3 = 8 +- ( )
To make this right, the number term must be -5.
3 = 8 - 5
So the equation is y = 2x - 5.
Answer:
15 shirts.
Step-by-step explanation:
A 20% discount means you still pay 80% of the price.
x represents the number of shirts that can be bought.
(20 x (1-0.2) )x = 240 or (20 x .8)x = 240
16 x = 240
x = 240/16 = 15
Determine the slope and y-intercept from the following equation: 4x + y = -10
Question 9 options:
slope: 4 y-intercept: (0,10)
slope: -4 y-intercept: (0,10)
slope: -4 y-intercept: (0,-10)
slope: 4 y-interce
