Answer: Aquaman swims at the rate of 140.47m/min
The rate of water drain is 73.81m/min
Step-by-step explanation: Let A be the rate at which Aquaman swims.
Let W be the rate at which the water drains
3(A - W)= 200 ......equation (1)
0.7(A +W)=150 ..... equation (2)
3A -3W = 200 .....equation 3
0.7A + 0.7W = 150 ..eq4
Multiply eq 3 by 7 and eq 4 by -30
21A - 21W = 1400
-21A + 21W = -4500
Subtracting both equation from each other, you get
-42W = -3100
W = 3100/42
W = 73.81m/min
Put 73.81 for W in equation 1
3A - 3(73.81) = 200
3A - 221.43 = 200
A =421.43/3
A= 140.47m/min
Data correlation is when two sets of data are strongly linked together when they have a High Correlation.
I can't see the multiple choice do u mind doing another pic :| sorry
13. AC=6
sorry it's just a guess i'm like 99% sure tho
