Answer:

-50 cents

Step-by-step explanation:

The "Winnings" random variable has values -1 and 499

The associated probabilities are P(-1)= 999/1000; P(499)=1/1000

-----------------------------

Expected Value = -1(999/1000) + 499(1/1000) = -500/1000 = -50 cents

Answer:

x = 15

m<RQP = 33degrees

Step-by-step explanation:

From the given diagram, m<P = 90degrees

Equating this to 5x+15

5x+15 = 90

5x = 90 - 15

5x = 75

x = 75/5

x = 15

m<RQP = 2x+3

m<RQP = 2(15) + 3

m<RQP = 30 + 3

m<RQP = 33degrees

The minute hand of a clock is 8 inches long and moves from 12 to 9 o'clock. How far does the tip of the minute hand move? Expr

IrinaK [193]

Answer: $12\pi$ inches

Step-by-step explanation:

Given : The minute hand of a clock is 8 inches long and moves from 12 to 9 o'clock.

From the attached image below ,

The angle made by minute hand from 12 to 9 o'clock (central angle) $=\dfrac{9}{12}\times360^{\circ}=270^{\circ}$

The length of the tip = radius (r)= 8 inches

The distance traveled by the tip of the minute hand = Arc formed from 12 to 9 o'clock.

Formula to find arc length = $\dfrac{\text{Central angle}}{360^{\circ}}\times2\pi r$

$=\dfrac{270^{\circ}}{360^{\circ}}\times2\pi (8)\\\\=12\pi$

Hence, the distance traveled by tip of the minute hand= $12\pi$ inches
