Answer:
E
Step-by-step explanation:
We were told Steven spent an amount of 50,000. Although the value of the dollar against the yen has changed. So therefore, to calculate the amount of money he spent, we would be needing to divide the amount he spent over the present exchange rate of the dollars to yen.
We then divide the 50,000 by 100 and that equals $500.
Hence, the amount of money spent by Steven is simply $500

Step-by-step explanation:
Let X be a discrete random variable with geometric distribution.
Let x be the number of tests and p the probability of success in each trial, then the probability distribution is:
P (X = x) = p * (1-p) ^ (x-1). With x = (1, 2, 3 ... n).
This function measures the probability P of obtaining the first success at the x attempt.
We need to know the probability of obtaining the first success at the third trial.
Where a success is defined as a customer buying online.
The probability of success in each trial is p = 0.3.
So:
P (X = 3) = 0.3 * (1-0.3) ^ (3-1)
P (X = 3) = 0.147
The probability of obtaining the first success at the third trial is 14.7%

Answer:
386.25
Step-by-step explanation:
To find 25 percent, we must first divide by four.
515 divided by 4 is 128.75
Now we mark off 128.75 USD
Basically, subtract 515 by 128.75
We're left with 386.25
