When the weight of apples is increased by a factor of 4, total cost increases by 8.
<h3>What is the increase in total cost?</h3>
The first step is to determine the relationship between the weight of apples and their total cost.
Relationship between weight and total cost = $2 / 1 = $2
Increase in total cost = $2 x 4 = $8

Answer:
Yes.. you are correct!
Step-by-step explanation:
Please give me brainliest.
The events A and B are not independent.
Given that,
P(A|B) = 0.4
P(A) = 0.5
P(B) = 0.8
Two events A and B are said to be independent, if P(A∩B) = P(A) P(B)
We have, P(A|B) = P(A∩B)/P(B)
Therefore, P(A∩B) = P(A|B) P(B) = 0.4 x 0.8 = 0.32
Now P(A) P(B) = 0.5 x 0.8 = 0.4
So P(A∩B) ≠ P(A)P(B)
Therefore, the events A and B are not independent.
