Which graph represents the following system of inequalities?<br> y &gt; 2x - 5<br> y &lt;-3x
NARA [144]

Answer:

The graph i the attached figure

Step-by-step explanation:

we have

y > 2x-5 ----> inequality A

The solution of the inequality A is the shaded area above the dotted line y=2x-5

The slope of the dotted line is positive

The x- intercept of the dotted line is the point (2.5,0)

The y- intercept of the dotted line is the point (0,-5)

y < -3x -----> inequality B

The solution of the inequality B is the shaded area below the dotted line y=-3x

The slope of the dotted line is negative

The x- intercept of the dotted line is the point (0,0)

The y- intercept of the dotted line is the point (0,0)

The solution of the system of inequalities is the shaded area between the two dotted lines

see the attached figure

P(A)=0.4 and P(B)=0.6. What is the probability of observing event B three times in a row?
Daniel [21]

Answer:

0.216

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

The probability that an event will happen added to the probability that the event will not happen gives 1. In other words, the outcome of a probability cannot exceed 1.

The probability that an event a will happen or that another independent event  b will happen is the sum of the probability that a will happen to the probability that b will happen.

The probability that the event B will occur 3 times in a row may be interpreted as BBB and in probability, "and" is interpreted as multiplication while "or" is addition.

Pr(BBB)

= 0.6 * 0.6 * 0.6

= 0.216
