Answer:
The Middle is 50, The outliers are 20 and 75
Step-by-step explanation:
Answer:
y = mx + b
therefore, the equation is y = -2/3x - 1
the -2/3 got the x because it is the slope and if you look at the formula, it tells you.
y-intercept is the starting point (b)
Step-by-step explanation:
Answer:
m=2/5
b=3.8
Step-by-step explanation:
To find slope you need to use slope formula which is (y2-y1)/(x2-x1) so you need two points from the table and plug them into this. I'll use the first two points (-2, 3) and (-1, 5)
(5-3)/(3--2)
2/5
our slope is 2/5(m)
now to find the y int(b)
we have out slope intercept formula which is y=mx+b
plug in our slope
y=2/5x+b
now take a random point from our tabell and apply it to our equation I'll use (-2, 3) again.
3=2/5(-2)+b
3=-4/5+b
3=-0.8+b
add 0.8 to each side
3.8=b
b=3.8
65.80/4 = 16.45
If she withdrew equal amounts each day, she would have had to withdrawn $16.45 each day.
