The range of this data is 65 since the minimum is 20 and the maximum is 85(if its counting by 5s) then you just subtract and you have the range.
Answer:
Step-by-step explanation:
The first step in calculating the mean is to add the numbers. After that you divide by the number of items in the data set. You don’t need to group the numbers to find the mean. Hope this helped!
Area of field=xy=5000
perimeter of field=2(x+y)300
x+y=150
x=150-y
y(150-y)=5000
solve it
u get y= 50 or 100
then x=100 or 50
therefore the dimensions are 100m and 50m
Answer:
M = 15
Step-by-step explanation:
To get m alone you need to subtract 4m by both sides
4m - 4m + 30 = 6m -4m
30 = 2m
Now last part is to divide 2 by both sides
30/2 = 2m/2
M = 15
