You can put this solution on YOUR website!

If 37% get less than 8 hours of sleep, 100%-37%=63%

63% get 8 hours or more per night:

(0.63)(2200)=1386

ANSWER: You would expect 1386 to get 8 or more hours of sleep per night.

This is an equation! Solutions: x=1.

Graphical form: Equation 3%2Ax-x%2B2=4 was fully solved.

Text form: 3*x-x+2=4 simplifies to 0=0

Cartoon (animation) form: simplify_cartoon%28+3%2Ax-x%2B2=4+%29

For tutors: simplify_cartoon( 3*x-x+2=4 )

Make a Matlab script to make row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2

stira [4]

Answer:

$X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}$

Step-by-step explanation:

From the question we are told that

Matrix is given as $A=\begin{Bmatrix}2 & -1 & 10\\-3 & 8 & 4\end{Bmatrix}$

Generally let the change in matrix be given as X

$X_1_2 = 2*(-(-1)) + - 1 = 1X_2_2 = -3 * (-(-1))+ 8 = 5$

Matlab output

$A=[2 -1 10;-3 8 4]\\a=(A(1,1)*-A(1,2))+A(1,2)\\b=(A(2,1)*-A(1,2))+A(2,2)\\X=[A(1,1) a A(1,3); A(2,1) b A(2,3)]\\$

Generally the matrix that makes row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row is

$X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}$
