How long will it take for a sum of $800 attracting simple interest to become $830 if the rate is 9%? Compute the return on this investment.

Answers

Answer:

5 months

ROI = 3.75 %

Step-by-step explanation:

Since,

The simple interest formula,

I=P* r* t

Where,

P = Principal amount,

r = rate per period ( in decimal )

t = number of periods,

Here, P = 800, r = 9% = 0.09,

If A is the future amount,

We have, A = 830

I = A - P = 830 - 800 = 30

By substituting the values in the above formula,

30=800* 0.09* t

30=72t

\implies t =(30)/(72)=(5)/(12)

Hence, it will take 5 months.  ( 1 year = 12 months )

Now,

\text{Return on investment }=(I)/(P)* 100

=(30)/(800)* 100

=3.75\%

T = m/c I think sorry if I’m wrong
To get T by itself - you need to both sides by m. The answer is t= c/m

(a) For a normal distribution, find the z-score that cuts off the bottom 55.76% of all the z-scores. Round to 2 decimal places after the decimal point. answer: (b) For a normal distribution, find the z-score that cuts off the top 77.52% of area. Round to 2 decimal places after the decimal point. answer:

Answers

Answer:

a) Z = 0.15

b) Z = -0.76

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = (X - \mu)/(\sigma)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

(a) For a normal distribution, find the z-score that cuts off the bottom 55.76% of all the z-scores.

Bottom 55.76% of the scores are the z-scores with a pvalue of 0.5576 and less. So the z-score that cuts off these scores is Z when X has a pvalue of 0.5576, which is Z = 0.145, rounded to two decimal places, Z = 0.15.

(b) For a normal distribution, find the z-score that cuts off the top 77.52% of area.

The top 77.52% of the scores are the z-scores with a pvalue of 1-0.7752 = 0.2248 and higher. So Z = -0.764 and higher. So the value that cuts off the top 77.52% is Z = -0.76.
