Answer:
The rate of interest for compounded annually is 6.96 % .
Step-by-step explanation:
Given as :
The principal amount = Rs 4600
The time period = 5 years
The amount after 5 years = Rs 6440
Let The rate of interest = R %
<u>From compounded method</u>
Amount = Principal × ![(1+\dfrac{\textrm rate}{100})^{\textrm Time}](https://tex.z-dn.net/?f=%281%2B%5Cdfrac%7B%5Ctextrm%20rate%7D%7B100%7D%29%5E%7B%5Ctextrm%20Time%7D)
or, Rs 6440 = Rs 4600 × ![(1+\dfrac{\textrm R}{100})^{\textrm 5}](https://tex.z-dn.net/?f=%281%2B%5Cdfrac%7B%5Ctextrm%20R%7D%7B100%7D%29%5E%7B%5Ctextrm%205%7D)
Or,
= ![(1+\dfrac{\textrm R}{100})^{\textrm 5}](https://tex.z-dn.net/?f=%281%2B%5Cdfrac%7B%5Ctextrm%20R%7D%7B100%7D%29%5E%7B%5Ctextrm%205%7D)
or, 1.4 = ![(1+\dfrac{\textrm R}{100})^{\textrm 5}](https://tex.z-dn.net/?f=%281%2B%5Cdfrac%7B%5Ctextrm%20R%7D%7B100%7D%29%5E%7B%5Ctextrm%205%7D)
Or,
= 1 + ![\dfrac{R}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7BR%7D%7B100%7D)
or, 1.0696 = 1 + ![\dfrac{R}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7BR%7D%7B100%7D)
or,
= 1.0696 - 1
Or,
= 0.0696
∴ R = 0.0696 × 100
I.e R = 6.96
Hence The rate of interest for compounded annually is 6.96 % . Answer
Answer:
1. Calculate the slope from 2 points.
2. Substitute either point into the equation.
3.Solve for b, which is the y-intercept of the line.
4. Substitute b, -1, into the equation from step 2.

Answer:
(d) 0.8736
Step-by-step explanation:
Unless you have a table of the normal distribution available, this is a calculator problem. Your calculator, or any spreadsheet, can tell you the probability is ...
P(-1.23 ≤ z ≤ 2.12) ≈ 0.8736
Step-by-step explanation:
Radius (r) = 2 ft
V = 4/3 × 22/7 × (2)³
= 4/3 × 22/7 × 8
= 33.52 ft³
