Answer:
f(d)=400(0.794)^d
Step-by-step explanation:
Answer:
A - (20% of A) = 80% of A + (20% of (80% of A) = 96% of A
So if A is 100:
100 - (.2 * 100) = 80 + (.2 * 80) = 96
Step-by-step explanation:
Answer:
Step-by-step explanation:
m + j + s = 37
j = 2s......s = j/2 or 1/2j
m = j + 2
(j + 2) + j + (1/2j) = 37
2j + 1/2j = 37 - 2
2j + 1/2j = 35....multiply everything by 2 to get rid of the fraction
4j + j = 70
5j = 70
j = 70/5
j = 14 < ==== Jan is 14
m = j + 2
m = 14 + 2
m = 16 <==== marcia is 16
s = 1/2j
s = 1/2(14)
s = 14/2
s = 7 <==== sydney is 7
Answer:
positive correlation
Step-by-step explanation:
When the y variable tends to increase as the x variable increases, we say that there is a positive correlation between the variables.
Therefore, the graph shows a positive correlation.
