Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$2x -1 > x + 2$

Solve for x

Subtract x both sides

$2x -1-x > x + 2-x$

$x-1 > 2$

Adds 1 both sides

$x-1 +1> 2+1$

$x> 3$

The solution is the interval -------> (3,∞)

All real numbers greater than 3

In a number line is the shaded area at right of x=3 (open circle)

see the attached figure

Step-by-step explanation:

This is in the form of

$h(x) = y$

in this case, x is 1 and y is 7. So ourbpoint would be (1,7.)

A game of chance involves rolling an unevenly balanced 4-sided die. The probability that a roll comes up 1 is 0.22, the probabil

GuDViN [60]

Answer:

Expected Winnings = 2.6

Step-by-step explanation:

Since the probability of rolling a 1 is 0.22 and the probability of rolling either a 1 or a 2 is 0.42, the probability of rolling only a 2 can be determined as:

$P_{1,2} = P_{1}+P_{2}\\P_{2} = 0.42 - 0.22 = 0.20$

The same logic can be applied to find the probability of rolling a 3

$P_{2,3} = P_{2}+P_{3}\\P_{3} = 0.54 - 0.20 = 0.34$

The sum of all probabilities must equal 1.00, so the probability of rolling a 4 is:

$P_{4} =1- P_{1}+P_{2}+P_{3} = 1-0.22+0.20+0.34\\P_{4}=0.24$

The expected winnings (EW) is found by adding the product of each value by its likelihood:

$EW=1*P_{1}+2*P_{2}+ 3*P_{3}+ 4*P_{4} \\EW=1*0.22+2*0.20+ 3*0.34+ 4*0.24\\EW=2.6$

Expected Winnings = 2.6
