"Rolling of a die" is an example of a random Experiment

Explanation

The formula for compound interest is:

A = P(1 + r/100)ⁿ

A = Amount

P = Principal

r = rate of interest

n = conversion period

In the given problem statement :

P = Rs. 1,00,000

r = 5%

n = 6 months

(i) Interest for six months

A = 1,00,000(1 + 5/100)¹

= 1,00,000(1 + 0.05)

= 1,00,000(1.05)

= 1,05,000

Interest for six months = 1,05,000 - 1,00,000

= Rs.5000

(ii) Amount for six Months = Rs. 1,05,000

(iii) Interest for next six months

A = 1,05,000(1 + 5/100)

= 1,05,000(1.05)

= 1,10,250

Interest for next six months = Rs. 1,10,250 - Rs. 1,10,000

= Rs. 5,250

(iv) Amount for One year = Rs. 1,10,250

Explanation

Explanation

Let the cost price of the article be ,x.

Then, sales price = x * 95/100 = 0.95 x

Now, 0.95 x = 1045

So, x = 1045/0.95 = Rs. 1100

Hence, sale price with 5 % profit = 1100 * 105/100 = Rs. 1155

Explanation

Ethnography is a method that is commonly used in qualitative research.

This type of research involves the study of a culture or group of people, usually through fieldwork.

ANS:

Mean proportional = √0.32 x 0.02
= √0.0064 = 0.08

Explanation

Given:

Cost price = $100

Selling price = $130

Find:

Profit =?

Solution:

profit = cost - selling 

profit = 100 - 130   

           = 30 rupees

Explanation

The arithmetic mean, also known as the average, is calculated by adding the two numbers and dividing by 2:

(4+6)/2 = 10 /2=5
So, the arithmetic mean between 4 and 6 is 5.

Explanation

ROI stands for Return on Investment

formula:

ROI = (Net Income / Initial Investment) * 100

Additional information:

NPV stands for Net present value

Explanation

When a pair of dice are tossed, there are 36 possible outcomes.

The combinations that result in a total of 7 or 11 are:

Total 7: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) = 6 outcomes

Total 11: (5,6), (6,5) = 2 outcomes

Total favorable outcomes = 6 + 2 = 8

Probability = (Number of favorable outcomes) / (Total possible outcomes)

Probability = 8/36 = 2/9

Explanation

If we add a constant (such as 3) to each observation of a data set, the mean will be increased by 3

This is because adding the same constant to each data point shifts the entire data set by that constant value, including the mean.
