6. Use the relation R={(1,2),(2,3),(2,4),(3,1),(3,4),(4 ,1),(4,2)} to draw the digraph. Use the Floyd and Warshall algorithm to calculate the shortest
path. The weight for each set is as follows:
[20 Marks]
(1,2) - 3
(2,3) = 12
(2,4)=5
(3,1) = 4
(3,4) = 4
(4,1)=2
(4,2)=-4

Which facts are true for the graph of the function below? check all that apply. f(x) = log8 x

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.

Which of these side lengths could form a triangle a) 2 cm , 2 cm , 4 cm b) 3 cm , 5 cm , 10 cm c) 3 cm , 4 cm , 5 cm d) 4 cm , 8 cm , 15 cm
