Question

There are 12 bags of apples on a market stall. the mean number of apples in each bag is 8. the table shows the number of apples in 11 of the bags. calculate the number of apples in the 12 bag.

Answer 1

Answer:

THERE ARE 12 APPLE BAGS ON A STALL

EACH BAG CARRIES 8 APPLE'S

MO. OF APPLES IN 12 BAGS =12×8

=96 ANSWER

Answer 2

Given is the mean number of apples for given bags, Find the number of apples in the twelfth bag.

Explanation:

• The question here is incomplete as the table for the number of apples in the bags is missing.
• Given below is the required table for the number of apples in each bag,
• $No.\ of\ apples(x_i)\ \ frequency(f_i)\\6\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1\\7\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4\\8\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2\\9\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3\\10\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1\\ x\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1\ \ \ \ \ \ \ \ \ \ ->12^{th}\ bag$    
• Assuming the number of apples in the twelfth bag to be 'x' we get its frequency count one as shown above in the table.
• Now we have that mean number of apples in each bag is $8$.
• Hence, $\bar x= 8$  
• $->\bar x=\frac{\sum f_ix_i}{N}\\ ->8= \frac{6(1)+7(4)+8(2)+9(3)+10(1)+x(1)}{12}\\->6+28+16+27+10+x=96\\->x=9$
• Therefore, the number of apples in the twelfth bag is $9$.
