The outcomes of rolling two cubes are shown in the table below (the outcomes is added up). The members of A are circled while the members of B are boxed. The members of A that also members of B is both circled and boxed.
P(A) = {3, 5, 7, 9, 11}
P(B) = {3, 6, 9, 12}
P(A∩B) = {3,9}
Answer:
Total number of fan = 80,495
Step-by-step explanation:
Given:
Number of fans attended = 77,098
Additional number of fans attended = 3,397
Find:
Total number of fan
Computation:
Total number of fan = Number of fans attended + Additional number of fans attended
Total number of fan = 77,098 + 3,397
Total number of fan = 80,495
The so-called "zeros" or "solutions" or "roots", are really just the x-intercepts, namely, where the graph touches or "intercepts" the x-axis, look at the graph, goes down and up and down again and up again, and hits the x-axis several times.
29)
what is "c", namely one of those x-values where it touches? look at the graph, it hits at 0.5, 1, 2, 3, pick your poison.
30)
how many? well, you already know.
Answer:
480 ways
240 ways
Probability = 1/7
Step-by-step explanation:
Given:
Number of student = 5
Number of teacher = 2
Computation:
1. Number of ways can they line up, side by side, for a picture.
5! × 2! × 2
480 ways
2. Number of ways can they line up if they must have the teachers on both sides of the picture.
5! × 2!
240 ways
3. Probability that the two teachers occupy two of the three middle slots.
³C₂ × 5! × 2!
720 ways
Total number = 7! = 5,040 ways
Probability = 720 / 5,040
Probability = 1/7
