The median of the numbers would be 7.5
The probabillity can be found by using binomial probability formular considering that the event is discrete in nature and there are two possiple outcomes.
Let B be the event that Andrea passes her test, and let A be the event
<span>that she studies. We are given that P(A and B) = 17/20, and that P(A) = 15/16. </span>
<span>Now the probability that Andrea passes her test given that she has studied </span>
<span>is represented by P(BlA). The formula your teacher gave you can be written as </span>
<span>P(BlA) = P(A and B) / P(A). </span>
<span>So P(BlA) = P(A and B) / P(A) = (17/20) / (15/16) = (17/20)*(16/15) = 68/75.</span>
Answer:
4x + y =6
Step-by-step explanation:
Line 8x + 2y = 12 is parallel to the line 4x + y = 6.
56 ÷ 2 = 28
28 + 28 = 56
