Let
l------> the length side of the rectangle
w----> the width side of a rectangle
b----> the base of the triangle
h----> the height of the triangle
we know that
the area of the yard is equal to
Solve for b------> ( that means clear variable b)
Subtract both sides
Divide by both sides
therefore
<u>the answer is the option B</u>
The quantity A minus l times w all divided by 0.5 times h
Answer : Remaining two observation becomes 97 and 107.
Explanation :
Since we have given that
Mean = 100
Modal value = 98
Range = 10
As we know that ,
Range = Highest-Lowest
Let highest observation be x
Let lowest observation be y
So equation becomes x-y=10 ----equation 1
So, observation becomes
x,98,98,y
Now, we use the formula of mean i.e.
Mean =
So, mean =
So our 2nd equation becomes
x+y=204
On using elimination method of system of linear equation on these two equation we get,
x=97
and
Hence , remaining two observation becomes 97 and 107.
