Answer:
The probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading is 1.
Step-by-step explanation:
The probability of an event <em>E</em> is the ratio of the favorable number of outcomes to the total number of outcomes.
Mutually exclusive events are those events which cannot occur together. They are also known as disjoint events.
If events <em>A</em> and <em>B</em> are mutually exclusive then:
The data provided is:
Opinion Like academic Dislike academic Total
reading reading
Liked recreational 136 40 176
reading
Disliked recreational 16 8 24
reading
Total 152 48 200
Denote the events as follows:
<em>X</em> = a person liked recreational reading.
<em>Y</em> = a person disliked recreational reading.
Compute the probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading as follows:
Thus, the probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading is 1.

Answer:
B. -0.2 + (-4.9)
Step-by-step explanation:
Subtracting a number is the same as adding its opposite. Subtracting 4.9 is the same as adding -4.9.
The appropriate choice is ...
-0.2 + (-4.9)

Step-by-step explanation:
How do u find the scale factor of a dilation?
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states
Answer:
x = 3
Step-by-step explanation:
29 - 3x = 5x + 5
You want to have the variable of x on one side of the equation, so add 3x to both sides.
29 = 8x + 5
You want to isolate the variable of x, so subtract 5 from both sides.
24 = 8x
You want the variable x on its own, so divide both sides by 8.
3 = x
Check your answer by plugging x back into the original equation.
29 - 3(3) = 5(3) + 5
Solve.
29 - 9 = 15 + 5
20 = 20
Your answer is correct!
