A rare coins value can be modeled with the equation W(x)=250(1.085)^x where x represents the number of years since the coin was
1 answer:
Answer:
250 is the initial value and 1.085 is the growth factor.
Step-by-step explanation:
A rare coin's value can be modeled with the equation
................. (1)
where x represents the number of years since the coin was first purchased and W(x) is the current worth of the coin.
Now, this equation (1) is an exponential growth function.
Here, 250 is the initial value as we get W(x = 0) = 250 and 1.085 is known as the growth factor which can not be equal to 1. (Answer)

Answer:
Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Step-by-step explanation:
Number of red socks = 2
Number of white socks = 6
Number of blue socks = 4
Total socks in drawer = 2+6+4 = 12
The formula used to calculate probability is:
We are given you draw out a sock, return it, and draw out a second sock.
We need to find the probability that the first sock is blue and the second sock is red?
Using formula:
Probability that first sock is blue = 4/12 = 1/3 = 0.33
Probability that second sock is red = 2/12 = 1/6 = 0.16
So, Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
