The answer would be 48 because....
First, you would multiply 80 and .40 (changed the percentage to decimal) which is 32
Then, subtract 80 and 32 to get 48
The sample space of an experiment is changed when some additional information pertaining to the outcome of the experiment is received. The effect of such information is to <u><em>reduce</em></u><em> </em>the sample space by excluding some outcomes as being impossible which before receiving the information were believed possible . The probabilities associated with such a <u><em>reduced</em></u> sample space are called conditional probabilities.
<u><em>Knowing a student’s grade level does not help determine if he or she uses social media.</em></u>
<u><em /></u>
The given survey explains the conditional probability.
The students of the<u><em> reduced</em></u> sample space i.e. of 9th grade have the probability of 81% who use the social media.
The students of 8th grade that use social media can be greater or less than 81%.
Therefore this experiment <u><em>does not</em></u> help determine if he or she uses social media on the basis of his/her grade.
Only the <u><em>last option </em></u>is correct.
The conditional probability can be understood by the following.

Answer:
Step-by-step explanation:
The general form of a quadratic equation is often written as ...
ax² +bx +c = 0
The references to "a", "b", and "c" are to the coefficients in this form. Comparing this to your equation ...
x²-3x -2 = 0
we see that the coefficient of x², is 1, so a=1; the coefficient of x is -3, so b=-3, and the constant is -2, so c=-2.
