Answer:
my place of work is a business
Answer:
$0.013
0.010724
Explanation:
Given that :
Mean, m = 36500
Standard deviation, s = 5000
Refund of $1 per 100 mile short of 30,000 miles
A.) Expected cost of the promotion :
P(X < 30,000)
Using the Zscore relation :
Zscore = (x - m) / s
Zscore = (30000 - 36500) / 5000
= - 6500 / 5000
= - 1.3
100 miles = $1
1.3 / 100 = $0.013
b. What is the probability that Grear will refund more than $50 for a tire?
100 miles = $1
$50 = (100 * 50) = 5000 miles
Hence, more than $50 means x < (30000 - 5000) = x < 25000 miles
P(x < 25000) :
(25000 - 36500) / 5000
-11500 / 5000
= - 2.3
P(z < - 2.3) = 0.010724 (Z probability calculator)
Answer:
a. 2 years
b. 1 year
c. 12 times
Explanation:
Interest period is the duration of the deposit. It is the length of time the money would remain in deposit. This is 2 years according to the question
Compounding period = number of times interest would be paid. In the question, this is a year. So interest would be paid every year
The compounding frequency - it is the number of times the deposit would be compounded. It is 12 months
The future value of the deposit can be determined using this formula :
FV = P (1 + r/m)^nm
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
Answer:
B. negative, positive
Explanation:
Substitution effect : Price rise of a good makes it relatively expensive, decreases its demand. Price fall of a good makes it relatively cheap, increases its demand.
So: Substitution Effect is always negative as per above explanation.
Income Effect : Price rise of a good decreases real income/ real purchasing power of consumer & reduces demand of all goods. Price fall increases real purchasing power & increases demand of all goods.
Income effect is positive in case of Normal Goods, normal good demand is positively related to income. The effect is negative in case of inferior goods, inferior good demand is negatively related to income.
Hence: Price rise of rice - Substitution effect results in negative change in rice consumption. {∵substitution effect always negative}
Income Effect leads to positive change in rice consumption {∵price rise reduces real income & income effect is negative for inferior goods}
