Step- Theby-step explanation:The answer is 21/2
This is the step:
(x-8)/5=2/4,then you can get (x-8)=(2/4) multiply by 5
(x-8)=10/4=5/2
x=(5/2)+8
x=21/2
Answer:
53$
Step-by-step explanation:
They tell you the equation of how much the coin is worth after x amount of years
Step 1: Substitute x=19 into the equation y=2x+15
y = 2(19) + 15
Step 2: Solve for y
y = 2(19) + 15
y = 38 + 15
y = 53
Therefore the coin is worth 53 dollars after 19 years
Answer:
answer A. 0.5
Step-by-step explanation:
hello
as A and B are independent P(B/A)=P(B) =0.5
in short, the information provided by the event A does not impact at all the event B. so knowing A or not does not impact the probability of B.
you can use the formula as well P(B/A)=P(A and B) / P(A)=(P(A)xP(B))/P(A)=P(B)
hope this helps
