Answer:

14 people read more than 3 hours last week

Step-by-step explanation:

See you have

3 hours which is 4 people

4 hours which is 6 people

So 6 people read more than 3 hours so far.

5 hours which is 3 people

So now you have 9 people that read more than 3 hours a week.

Then you have 6 hours which is 5 people

So

6 + 3 + 5= 14

Hope this helps!~

Create a matrix that is equal to F+G. The first matrix below is named F and the second matrix below is named G. Name the new mat
likoan [24]

F+G:

F+G=\begin{bmatrix}{-1.8} & {-8.6} & {} \\ {2.85} & {-1.4} & {} \\ {-1.8} & {5.1} & {}\end{bmatrix}+\begin{bmatrix}{1.32} & {-1.9} & {} \\ {2.25} & {0.0} & {} \\ {-6.2} & {1.4} & {}\end{bmatrix}

Then, add the elements that occupy the same position:

H=\begin{bmatrix}{-1.8+1.32} & {-8.6+(-1.9)} & {} \\ {2.85+2.25} & {-1.4+0.0} & {} \\ {-1.8+(-6.2)} & {5.1+1.4} & {}\end{bmatrix}

Solve

H=\begin{bmatrix}{-0.48} & {-10.5} & {} \\ {5.1} & {-1.4} & {} \\ {-8} & {6.5} & {}\end{bmatrix}

So, we find the element at address h31:

H=\begin{bmatrix}{h11} & {h12} & {} \\ {h21} & {h22} & {} \\ {h31} & {h32} & {}\end{bmatrix}

In this case, position h31 is - 8.0

Write an equation in slope-intercept form that passes through each pair of points. (0, 1) (-3, 1)
lina2011 [118]

Answer:

y =  \frac{0}{ - 3}  + b

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is the y intercept

We'll find slope first.

slope formula is

\frac{y2 - y1}{x2 - x1}

y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.

So we just put the given values into our equation.

\frac{1 - 1}{ - 3 - 0}

Simplify

\frac{0}{ - 3}

Now we put this into our y=mx+b

y=0/-3x+b

now we need the (b)

to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.

y =  \frac{0}{ - 3} x + b

1 =  \frac{0}{ - 3} (0) + b

Solve

1=0+b

b=1

Put this in our formula

y =  \frac{0}{ - 3}  + 1

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
