Answer:
I believe the correct answer would be the last one.
Step-by-step explanation:
The units are supposed to be blocked by gender. However, the first two units in the final option are blocked with two females in one group, and two males in the next. This is inconsistent with the blocking method used for the rest of the units.
Answer:
b)
Step-by-step explanation:
Answer:
{1, -9, 56, -269}
Step-by-step explanation:
Evaluate the rule for n=2, 3, and 4 in sequence.
For n=2
f(2) = (-5)f(1) +11 = (-5)(4) +11 = -9
f(3) = (-5)f(2) +11 = (-5)(-9) +11 = 56
f(4) = (-5)f(3) +11 = (-5)(56) +11 = -269
The first four terms of the sequence are {1, -9, 56, -269}.
The ratio of x:y:z = 20:8:11
Total unit = 20+8+11 = 39
Value of 1 unit ratio = 78/39 = 2
So, the water in container X, 20(2) = 40 liters
Your answer is 40 liters
