1 answer:
Answer: 0.0080
Step-by-step explanation:
Given : The manufacturer's website states that the average weight of each stick is oz with a standard deviation of
oz.
We assume the weight of the drumsticks is normally distributed.
Using formula , the z-value corresponds x=2.66 will be :-
By using the standard normal distribution table for z, we get
P-value =
Hence, the probability of the stick's weight being 2.66 oz or greater=0.0080

Step-by-step explanation:
It is given that:
Monthly Rent = A
Total Money Paid to Landlord = Y
The landlord requires initial payment to include:
- 1st month's rent
month's rent or 50% of monthly rent for Security Deposit
- 40% of monthly rent for utility bills
- 5% of monthly rent for health club
- 13% of monthly rent per person for other services
Also, Total Amount Paid to the Landlord = $2574
Number of People Sharing the Apartment = 3
Basis the above information,
Y = (100% * A) + (50% * A) + (40% * A) + (5% * A) + (13% * A * 3)
⇒ Y = A + (0.5 * A) + (0.4 * A) + (0.05 * A) + (0.39 * A)
⇒ Y = A + (0.5 * A) + (0.4 * A) + (0.05 * A) + (0.39 * A)
⇒ Y = 2.34 * A
Substituting the value of Y to determine A
⇒ 2,574 = 2.34 * A
⇒ A = 1,100
Hence, the monthly rent is $1,100
