Answer:
Step-by-step explanation:
Assuming the following data
X: 44, 44, 11, 11, 55
Y: 66, 55, -1, -3, 88
We want to find a linear model
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:

Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3
Answer:
Step-by-step explanation:
We are given that
Side of square shaped piece= 3ft
Let square of side x cut from each corner of square piece cardboard.
Length of box=
Breadth of box=
Height of box= x
We have to find the largest volume of box.
Volume of box is given by
Differentiate w.r.t x
Substitute
Again differentiate w.r.t x
Substitute
Substitute
Therefore, at
Hence, the volume is maximum at
Substitute the value then we get
Answer:
total marbles in the box is 600
