In the formula l=p+prt, what does l equal when p=500,r=20%, t=2

1 answer:

7 0

Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:

$I=p+prt\\I=(500)+(500)(0.2)(2)\\I=500+200\\I=700$

So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.

Well just think, what is the ten thousands place? 1 right by 6. From this to round you look at the previous number 6, anything 5 or above will be rounded up making the 1 into a 2, anything lower than a 5 will become rounded down making the 1 stay the same, but instead making it into 10,000
So the answer would be 20,000

In preparation for an earnings report, a large retailer wants to estimate p= the proportion of annual sales

mr Goodwill [35]

Using the z-distribution, it is found that the 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.
