Solve the Quadratic Equation By Completing the Square<br> b^2-15b-54=0

vladimir1956 [14]

$b^{2}-15b-54=0. \newline
b^{2}-15b=54. \newline
b^{2}-15b+(\frac{15}{2})^{2}=54+(\frac{15}{2})^{2}. \newline
(b-\frac{15}{2})^{2}=\frac{441}{4}. \newline
b-\frac{15}{2}=\pm\frac{21}{2}. \newline
b=\pm\frac{21}{2}+\frac{15}{2}. \newline
b_1 = -3, b_2 = 18.$

bekas [8.4K]

Answer:

A and B are exhaustive.

Step-by-step explanation:

Given

$A = \{1,2,4\}$

$B = \{2,3,4,5,6\}$

$C =\{3,4\}$

$D = \{2,4,5\}$

Solving (a): The mutually exclusive events

These are events that have no common or mutual elements

Events A to D are not mutually exclusive because each of the events have at least 1 common element with one another.

Solving (b): Exhaustive events.

Two events X and Y are said to be exhaustive if:

$S = P(X\ n\ Y)$

i.e. if the sample space equals the intersection of X and Y

For events A to D, we have:

$A\ n\ B = \{1,2,3,4,5,6\}$

and the sample space is:

$S = \{1,2,3,4,5,6\}$

By comparison;

$A\ n\ B = S$

Hence, A and B are exhaustive.
