Answer:
1
Step-by-step explanation:
x+y=1 if x=0, then y=1
29 I think but iam not sure if it’s right
0.02/0.64*100=3.125℅
The formula is:(/error/divided by right answer) times 100. /means absolute value
E + w = 50.....w = 50 - e
25e + 20w = 1090
25e + 20(50 - e) = 1090
25e + 1000 - 20e = 1090
25e - 20e = 1090 - 1000
5e = 90
e = 90/5
e = 18 <=== the east got 18
w = 50 - e
w = 50 - 18
w = 32 <=== the west got 32
Answer: Z.
Step-by-step explanation:
They want you to figure formula then find right graph, but do it fastest way. If it doubles each year, graph can't be straight line, eliminate Y.
A(0) has to be $5, eliminate W. A(1) has to be double A(0), eliminate X. Check: Z shows A(1) is 10, A(2) is 20.
