(Hint :- I want the correct answer 8.32 with correct explanation ) this Q if from ex 14.3 of 10th math)
now answer it correctly for 10 points. Fast​

Answer 1

Given

• Median = 8.05
• Mode = 7.88

⠀

To find

• Mean of the data.

⠀

Solution

• The empirical relationship between mean, median and mode is :-

⠀

☆ Mode = 3Median - 2Mean

⠀

• Putting the values

⠀

→ 7.88 = 3(8.05) - 2Mean

⠀

→ 7.88 = 24.15 - 2Mean

⠀

→ 2Mean = 24.15 - 7.88

⠀

→ 2Mean = 16.27

⠀

→ Mean = 16.27/2

⠀

→ Mean = 8.135

⠀

Hence,

• Mean of the data is 8.135 units.

Answer 2

Answer:

u can use the formula : mode = 3 median - 2 mean

Step-by-step explanation:

7.88 = 3 (8.05) - 2x

7.88 = 24.15 - 2x

2x = 24.15-7.88

2x = 16.27

x = 16.27/ 2

x = 8.135

mean = 8.135
