At what time the sum Rs. 5000 will be doubled at the interest<br>of 10% per annum?

FromTheMoon [43]

Answer:

Time= $10$ years

Step-by-step explanation:

Let total time $=t$

Initial Amount $=5000$

Final Amount $=10000$

Total interest = Final Amount - Initial Amount

$=10000-5000\\=5000$

Simple Interest $=\frac{Initial Amount\times time\times rate}{100} \\\\5000=\frac{5000\times t \times 10}{100}\\\frac{t}{10} =1\\t=10 \ years$

Answer:

y = $\frac{t}{a+v}$

Step-by-step explanation:

From the records of a health-insurance companies in Pennsylvania, it is known that 58% of the accounts include dental coverage.

kobusy [5.1K]

Answer: 0.0221

Step-by-step explanation:

We know that the formula to find the standard deviation of the sample proportion is :

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}$

, where p = proportion of success.

n= sample size.

As per given , we have

p=0.58

n= 500

Then, the standard deviation of the sample proportion in this situation would be :

$\sigma_p=\sqrt{\dfrac{0.58(1-0.58)}{500}}\\\\=\sqrt{\dfrac{0.2436}{500}}\\\\=\sqrt{0.0004872}\\\\\approx0.0221$

Hence, the standard deviation of the sample proportion in this situation is 0.0221 .
