Builtrite has calculated the average cash flow to be $12,000 with a standard deviation of $4,500. What is the probability of a c

UkoKoshka [18]

Answer:

Step-by-step explanation:

Use the normcdf( function on a basic calculator as follows:

normcdf(-1000, 9750, 12000, 4500). Result: 0.307. This is the area under the standard normal curve to the left of 9750.

But we want the area under the standard normal curve to the right of 9750, so we subtract this 0.307 from 1.000, obtaining the desired result: 0.693. This roughly corresponds with the last of the given possible answers, 69.15%.

Deonte invested 200000at his bank for 10 years if he earned 130000 what was the interest rate the bank gave him

Volgvan

Answer:

The interest rate the bank gave Deonte is 6.5%.

Solution:

Given, Deonte invested 200000 at his bank for 10 years

He earned 130000

We have to find what was the interest rate the bank gave him.

Now we know that, simple interest $=\frac{\text {amount} \times \text {rate} \times \text {time}}{100}$

So, by substituting our values in above formula,

$130000=\frac{200000 \times \text { rate } \times 10}{100}$

Interest rate $\times$ 20000 = 130000

Interest rate $\times$ 2 = 13

$\text { Interest rate }=\frac{13}{2}=6.5 \%$

Hence, the interest rate given by bank is 6.5% to Deonte.
