Answer:
Step-by-step explanation:
You can simply count the number of unit cubes.
There are 11 cubic units.
Let’s take Sanku as x.
if Madhu is 3 times his age, then he is 3x.
the difference in their age is 14, so
3x - x = 14
2x = 14
x=7
Sanku is 7
Madhu is 21
The mean is all the numbers added up and then divided by how many x's there are. In this case, it's 27+29+32+32+36+38+38+42+42 = 345, then you divide it by 9 (the number of x's) and you get 38.33
The median you be the number in the center of the string of numbers, 36 in this number line, because there are nine numbers total and 36 has four numbers on each side
27, 29, 32, 32, 36, 38, 38, 42, 42
The range is the biggest number minus the smaller number, 42-27
So the range is 15
Answer:
18
Step-by-step explanation:
If he has worked for 9 hours and its 50% done he has to work for 9 more hours to get it finished so he would have worked on it for 18 hours to get it totally finished
400, due to the last nine being over the 5 median
