Answer: The constant of variation value of 7.
Step-by-step explanation: We are given cost of 0.8 meter of a silk ribbon = $5.60.
Let us assume y be the total cost for x meter of a silk ribbon and k is the constant of variation.
So, we can set up an equation for proportion relationship:
y = k x.
<em>Let us plug x=0.8 and y= 5.60,</em> in above proportion relationship equation, we get
5.60 = k (0.8).
Dividing both sides by 0.8, we get
5.60/0.8 = k(0.8)/0.8
k =7.
Therefore, the constant of variation value of 7.
Answer:
C. 0.12
Step-by-step explanation:
<u>Independent events</u>
The outcome of one event does not affect the outcome of the other. If A and B are independent events then the probability of both ocurring is:
P(A and B) = P(A) x P(B)
With P(A) = 0.40 and P(B) = 0.30 then
P(A and B) = 0.40 x 0.30 = 0.12
