An experiment has four equally likely outcomes: E1, E2, Es, and E.Round your answers to three decimal places. a. What is the pro
V125BC [204]

Answer:

a. 0.25

b. 0.50

c. 0.75

Step-by-step explanation:

P(E1) = 0.25

P(E2) = 0.25

P(Es) = 0.25

P(E) = 0.25

a. Since there are 4 outcomes with the same probability of occurring, the probability of E occurring is:

P(E) = \frac{1}{4}=0.25

b. The probability of any two outcomes occurring is twice the probability of a single outcome occurring

P(two\ outcomes) = 2*P(one\ outcome) = \frac{2}{4}=0.50

c. The probability of any three outcomes occurring can be written as 100% minus the probability of the remaining outcome occurring

P(three\ outcomes) = 1-P(one\ outcome) = 1-\frac{1}{4}=0.75

Solve using law of sines or law of cosines!
malfutka [58]

Answer:

Part 5) The length of the ski lift is 1.15\ miles

Part 6) The height of the tree is 18.12 m

Step-by-step explanation:

Part 5)

Let

A -----> Beginning of the ski lift

B -----> Top of the mountain

C -----> Base of mountain

we have

b=0.75\ miles

A=20\°

C=180\°-50\°=130\° ----> by supplementary angles

Find the measure of angle B

Remember that the sum of the interior angles must be equal to 180 degrees

B=180\°-A-C

substitute

B=180\°-20\°-130\°=30\°

Applying the law of sines

\frac{b}{sin(B)}=\frac{c}{sin(C)}

substitute

\frac{0.75}{sin(30\°)}=\frac{c}{sin(130\°)}

c=\frac{0.75}{sin(30\°)}(sin(130\°))

c=1.15\ miles

Par 6)

see the attached figure with letters to better understand the problem

<u><em>Applying the law of sines in the right triangle BDC</em></u>

In the right  triangle BDC 20 degrees is the complement of 70 degrees

\frac{BC}{sin(70\°)}=\frac{x}{sin(20\°)}

BC=(sin(70\°))\frac{x}{sin(20\°)} -----> equation A

<u><em>Applying the law of sines in the right triangle ABC</em></u>

In the right  triangle ABC 50 degrees is the complement of 40 degrees

\frac{BC}{sin(40\°)}=\frac{x+15}{sin(50\°)}

BC=(sin(40\°))\frac{x+15}{sin(50\°)} -----> equation B

Equate equation A and equation B and solve for x

(sin(70\°))\frac{x}{sin(20\°)}=(sin(40\°))\frac{x+15}{sin(50\°)}\\\\2.7475x=0.8391(x+15)\\\\2.7475x=0.8391x+12.5865\\\\2.7475x-0.8391x=12.5865\\\\x=6.60\ m

<u><em>Find the value of BC</em></u>

BC=(sin(70\°))\frac{6.6}{sin(20\°)}

BC=18.12\ m

therefore

The height of the tree is 18.12 m
