Calculate the mean number of students per class at watch school. Write your answers in sentences that explain what the means rep
Tpy6a [65]
To find the mean you add all the numbers then divide the sum by how many numbers there are :

1)Ford School
   
21+19+20=60

there are 3 numbers in the equation so you divide 60 by 3 :

60÷3=20

the mean for Ford School is 20

2)Carter School

41+36+37=114

there are 3 numbers in the equation so you divide 114 by 3 :

114÷3=38

the mean for Carter School is 38

hope this helps

Find all the roots of the equation x4 - 2x3 + 14x2 - 18x + 45 = 0 given that 1 + 2i is one of its roots.

brainly.com/question/10192511


Knowing that 1+2i is a root, you also know that 1-2i is a root, so one quadratic factor is
   (x -1)² -(2i)² = x^2 -2x +5

Long division of the given polynomial by this quadratic gives a quotient of 
  x² +9
which has roots ±3i.

Then all the roots are {-3i, 3i, 1-2i, 1+2i}.

A box is to be made from a rectangular piece of corrugated​ cardboard, where the length is 8 more inches than the​ width, by cut
Ksenya-84 [330]
The volume of a box like this is found by multiplying the length times the width times the height.  We are told that the length is 8 more inches than the width, so the width is w and the length is w + 8.  If we cut away 3 square inches from each corner, the height when we fold up those corners is going to be 3.  The volume is given as 27, so our formula looks like this:  27=(3)(w)(w+8).  When we do that multiplication, we have  27=3w^2+24w.  We need to solve for w so we can then solve for h.  Move the 27 over and set the quadratic equal to 0.  3w^2+24w-27=0.  We can then factor out a 3 to make the job easier:  3(w^2+8w-9)=0.  Now we can factor to solve for w.  The 2 numbers that add up to 8 and multiply to -9 are 9 and -1.  So (w+9) = 0, (w-1) = 0, or 3 = 0.  Of course 3 doesn't equal 0, so that's out.  w + 9 = 0 so w = -9.  w - 1 = 0 so w = 1.  There are 2 things in math that can never EVER be negative and those are time and distance/length.  So -9 is out.  That means that w = 1.  But don't forget that there was 6 inches cut off each side, so the width is 1 + 3 + 3 which is 7.  The length is w + 8 which means that the length is 7 + 8 or 15.  Those are the dimensions of the rectangle before it was cut.
