Explanation

The arithmetic mean is calculated by adding all the observations and dividing by the number of observations.

Given observations: 5, 5, and 5.

$$text{Mean} = frac{5 + 5 + 5}{3} = frac{15}{3} = 5$$

=15/3​

=5

Explanation

COGS is deducted from revenues (sales) to calculate gross profit and gross margin.

The formula for gross profit is:

Gross Profit = Revenue - COGS.

Explanation

Explanation

Let number of coins = 3x, 5x, 4x
→ Total value = 264
→ $3x+10x+20x=33x=264\Rightarrow x=8$

$\mathrm{<br>}$2 coins = 5x = 5 × 8 = 40 coins
→ Value = 40 × 2 = 80 

So to get 66, x = 6

33x = 264 → x = 8
33x = 198 → x = 6 → 3x = 18 coins → 1 coins = 18

So likely in your example:

• Ratio = 3:5:4

• Total = 198

• x = 6

• 2 coins = 5x = 30 coins

• Value = ₹60

So if 2 coins value = 66, x = 6.6, which is not clea

Explanation

To find the Arithmetic Mean (AM), we need to sum all the values and divide by the number of values:

Values: 2, 3, 4, 5, 6, 7, 8, 9, 10

Sum = 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

= 54

Number of values = 9

Arithmetic Mean = Sum / Number of values

= 54 / 9

= 6

Explanation

The mode is the digit that appears most frequently in the data set.

Let's count the occurrences of each digit:

• 0: 3 times
• 1: 2 times
• 2: 1 time
• 3: 2 times
• 5: 1 time
• 6: 2 times
• 7: 1 time
• 9: 1 time

The digit 0 appears most frequently, 3 times. Therefore, the mode is 0.

Explanation

5 ! = 5 × 4 × 3 × 2 × 1 = 120 ways.
