Answer:

(b) $1.15

Step-by-step explanation:

The expected value is the sum of products of payoff and probability:

$0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05

= $0 +0.25 +0.20 +0.20 +0.50

= $1.15 . . . . expected value of the scratch ticket

Angle measures and segment lengths. Algebra Find the value of each variable.

dolphi86 [110]

Answer:

x = 60°

Step-by-step explanation:

According to the Outside Angles Theorem, the angle formed by the two tangents in the diagram above is equal to half of the difference of the measures of two arcs that are intercepted.

Therefore:

$x = \frac{1}{2}(360 - 120) - 120)$

$x = \frac{1}{2}(240 - 120)$

$x = \frac{1}{2}(120)$

x = 60°

The some of the numbers is 77. The greater number is 5 more than the smaller number.Which equation can be used to solve for the

QveST [7]

Let the smaller number be x and the larger one be y

x + y = 77

y = x + 5

Substituting into the first equation

x + (x + 5) = 77

2x + 5 = 77

Subtracting 5 to both sides

2x +5 -5 = 77-5

2x = 72

Divide both sides by 2

2x/2 = 72/2

x = 36
