Assume the annual mean return on ABC stock is around 15%, and the annual standard deviation is around 25%. Assume the annual and daily returns on ABC stock are normally distributeda what is the probability that ABC will lose money during a year?b Thereis a 5% change that ABC will earn a return of at least what value during a year?c There is a 10% change that ABC will earn a return of less than or equal to waht value during a year?d what is the probability that ABC will earn at least 35% during a year?e Assume there are 252 trading days in a year. What is the probability that ABC will lose money on a given day?(Hint: Let Y be the annual return on ABC and Xi be the retun on ABC on day i. Then Y=x1+x2++x252. Use the fact that the sum of independent normal random variables is normally distributed, with mean equal to the sum of the individual means and variance equal to the sum of the individual variances.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
