Answer:
A. .
Step-by-step explanation:
We are given that,
x = Number of days where 1 = Sun of 1st week and 7 = Sat of first week.
The corresponding table for the data is given by,
Days Day Number Number of Customers
Sun 1 115
Mon 2 77
Tue 3 60
Wed 4 51
Thur 5 68
Fri 6 86
Sat 7 120
The general form of the regression model is .
Using the sinusoidal regression calculator, we get that,
a = 33.690
b = 0.887
c = 1.337
d = 81.684
That is, the sine regression model is .
Thus, option A is the sine regression model for the given data.
Answer:
To earn $10 in 1st month, the principal must be $4,000.
No, the poster cannot claim that "Open an account of $2 comma 500 and earn at least $10 interest in 1 month!".
Step-by-step explanation:
We have been given that a bank manager wants to encourage new customers to open accounts with principals of at least $2,500. He decides to make a poster advertising a simple interest rate of 3%. We are asked to find the principal to advertise that one can earn $10 the first month.
We will use simple interest formula to solve our given problem.
, where,
I = Amount of interest,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
1 month will be equal to .
Therefore, to earn $10 in 1st month, the principal must be $4,000.
Now, we will check if an account of $2,500 can earn at least $10 interest in 1 month.
Since the account earns an amount of $6.25 in one month, therefore, the poster is not true.
