Answer:
5 presents
Step-by-step explanation:
40 presents in 2 hours
20 presents in 1 hour (divide by 2)
20 presents in 60 minutes ( 1 hour is 60 minutes )
5 presents in 15 minutes ( divide by 4)
The median is 7.
——————————
Arrange data in numerical order
1 3 3 6 8 10 10 15
Total number are 8, N = 8
Take the middle two numbers 6 and 8 and take their average
6+8/2 = 14/2 = 7
Therefore the median is 7.
Step-by-step explanation:
Profit of white cement = 8 per bag
Loss of Grey cement = 5 per bag
A 3000 bags of white cement = 3000 x 8 = 24000
5000 bags of Grey cement = 5000 x 5 = 25000
So the company recieved a loss of $1000
B number of grey bags sold = 6400
= 6400 x 5 = 32000
If there are 4000 white bags = 4000 x 8 = 32000
Then there will be neither loss nor profit
