Answer:
The loan amount after 3 years is $ 5,196.88
Step-by-step explanation:
Given as :
The principal amount for room loan = $ 3,800
The rate of interest applied = 11% compounded annually
The time period of loan = 3 years
Let The Total loan amount = $ A
Now,<u> From Compounded method :</u>
Amount = Principal ×
or, A = $ 3,800 ×
or, A = $ 3,800 × (1.11)³
or, A = $ 3,800 × 1.3676
∴ A = $ 5,196.88
So, Amount after 3 years = A = $ 5,196.88
Hence The loan amount after 3 years is $ 5,196.88 Answer
Answer:
0.6856
Step-by-step explanation:
Now; assuming X = no of complaints received in a week
Required:
To find P(77 < X < 120)
Using a Gaussian Normal Distribution (108,
= 20)
Using Z scores:
As a result X = 77 for N(108,20) is approximately equal to to Z = -1.75 for N(0,1)
SO;
Here; X = 77 for a N(108,20) is same to Z = 0.6 for N(0,1)
Now, to determine:
P(-1.75 < Z < 0.6) = P(Z < 0.6) - P( Z < - 1.75)
From the standard normal Z-table:
P(-1.75 < Z < 0.6) = 0.7257 - 0.0401
P(-1.75 < Z < 0.6) = 0.6856
The point slope formula:
Substitute:
