Answer: The loan have been $2500 originally.
Step-by-step explanation:
Since we have given that
Interest = $750
Rate of interest = 3%
Number of year = 1
Let P be the principal amount .
So, According to question, we get that
![750=\dfrac{P\times R\times T}{100}\\\\750=\dfrac{P\times 3\times 1}{100}\\\\\dfrac{750\times 100}{3}=P\\\\$2500=P](https://tex.z-dn.net/?f=750%3D%5Cdfrac%7BP%5Ctimes%20R%5Ctimes%20T%7D%7B100%7D%5C%5C%5C%5C750%3D%5Cdfrac%7BP%5Ctimes%203%5Ctimes%201%7D%7B100%7D%5C%5C%5C%5C%5Cdfrac%7B750%5Ctimes%20100%7D%7B3%7D%3DP%5C%5C%5C%5C%242500%3DP)
Hence, the loan have been $2500 originally.
Answer:
![z = -0.340](https://tex.z-dn.net/?f=z%20%3D%20-0.340)
Step-by-step explanation:
We are given that Z is a standard normal variable.
We have to find the value of z such that
P(Z > z) = 0.6331
Calculation the value from standard normal z table, we have,
![P(z \leq -0.340) = 0.3669](https://tex.z-dn.net/?f=P%28z%20%5Cleq%20-0.340%29%20%3D%200.3669)
Thus,
![z = -0.340](https://tex.z-dn.net/?f=z%20%3D%20-0.340)
