Answer:
10.5
Step-by-step explanation:
there are 2 middle values when you have an even number of data items so you must take their average
(10+11)/2 = 21/2 = 10.5
Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4
slope=1/4
y=mx+b
m=slope
b=yint
solve for yint
input a point
(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b
y=1/4x+4
Answer:
Step-by-step explanation:
Hi
15/3 = 5
24/3 = 8
15/24 = 5/8
Answer: 5/8
42 = 40(x-1) + 40
x-1 will be equal to the sales tax rate in this equation.
