Answer:
The solution to the equation is:
- <u>x = 2.5</u> or <u>x = 5/2</u>
Step-by-step explanation:
To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:
And we solve:
- 4x + 28 = 38 (we multiply 4 by x and 7)
- 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
- x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
- <u>x = 2.5</u> (we divide)
As you can see, <u><em>the solution of the equation is </em></u><u><em>x = 2.5</em></u><u><em> or </em></u><u><em>x = 5/2</em></u>

Answer:
0.4833
Step-by-step explanation:
We want GIVEN THAT 200 pages or MORE AND RETURNED ON TIME.
Returned on time
fewer than 200 pages—— 78
200 pages ir more ——116
Returned late
Fewer than 200 pages ——15
Returned late ——31
The first table is returned on time and last row is 200 pages or more, so we take that value "116".
To get probability, we also need the total. We add up all those 4 values:
78 + 116 + 15 + 31 = 240
Thus, probability is = 116/240 = 0.4833
