30 points.. Please Help! I don't understand what to do with this question...a bit confused.
Romashka-Z-Leto [24]
  Eh, here's my best try for a table:

                       <u>Like tv</u>          <u> don't like tv</u>       <u>total</u>
<u>Like reading:</u>     70                     10                 80
 <u>Don't like read</u>. <u>20</u>                     <u>30</u>               <u>50 </u> 
      <u>total </u>              90                    40               130

The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.

The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]

Hope this somehow helped you :)

Write and solve an addition or subtraction equation to find the missing angle measure
sergiy2304 [10]

Answer:

n + 50 = 90; n = 40

Step-by-step explanation:

the angle is a right angle so it adds up to 50

one side is 50

so

n + 50 = 90

subtract 50 to both sides

n = 40

(3,1) m=0<br> In standard form
diamong [38]

0x + y = 1 is the standard form of (3, 1) with m = 0

<u>Solution:</u>

We have been given a point and slope of an equation and have been asked to write it in the standard form.

The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.

The given point is (3,1) and the slope is 0

To write in standard form we will first write it in point slope form and then rearrange it into a standard from.

The point slope form of line is given as:

y-y_{1}=m\left(x-x_{1}\right)

Where "m" is the slope of the line

Here in this problem, m = 0 , x_1 = 3 and y_1 = 1

y - 1 = 0(x - 3)

y - 1 = 0

y = 1

since the above equation doesn’t have an ‘x’ term we convert into a standard form as follows:

0x + y = 1

This is the standard form for the given point and slope of a line.
