Answer:

Interior: 8640°

Exterior: 360° (Every shapes' exterior angle sum is 360°)

Step-by-step explanation:

Formula: 180(Sides - 2)

180(50-2) = 180(48) = 8640

You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with

shtirl [24]

Answer:

The probability that the person reaches home for the holidays is 0.94.

Step-by-step explanation:

A person wants to go home for Thanksgiving and he has booked a flight with US-Scareways.

It is provided that in 30 percent of the cases the company has canceled the flight you were on.

SO there is 70% chance of reaching home without any difficulties.

In case the flight is cancelled, then as a backup the person's friend Walter offers a ride home.

Walter also has a 80% chance of giving the ride. So there is 20% chance the person will not be able to reach hone if his flight gets cancelled.

Consider the tree diagram below.

The events are:

FC = flight is cancelled

FT = Flight is on time

H = reaches home

Compute the probability that the person reaches home as follows:

P (Reaching Home) = P (H|FC) × P (FC) + P (FT)

$=(0.80\times 0.30) +0.70\\=0.24+0.70\\=0.94$

Thus, the probability that the person reaches home for the holidays is 0.94.

A pilot flies on a bearing of 160° for 30 miles. The pilot then executes a quick turn and flies another 15 miles at a bearing of

vivado [14]

Answer: 34.65 miles at an angle of 325.39°

Step-by-step explanation:

Ok, the initial position is (0,0)

Then she flies 30 miles at an angle of 160°, if we count the angle counterclokwise from the x-axis, the new position will be:

p = (30*cos(120°), 30*sin(120°))

Then she travels another 15 miles at an angle of 205°, the new position is:

p = (30*cos(120°) + 15*cos(205°), 30*sin(120°) + 15*sin(205°))

p = (-28.59 , 19.64)

If she now travles X miles at an angle Y, we must have that the final position is the point (0,0)

this means that:

X*cos(Y) = -(-28.59) = 28.59

X*sin(Y) = -19.64

Now, we can find the quotient between those two equations and use that tan(x) = sin(x)/cos(x)

X*(sin(Y))/(X*cos(Y)) = -19.64/28.59

Tg(Y) = -0.69

Y = ATg(-0.69) = -34.61°

If we use only positive angles, this angle is equivalent to:

360° - 34.61° = 325.39°

now lets find the distance:

Xcos(325.39°) = 28.59

X = 28.59/cos(325.39°) = 34.65 miles.

Factor the expression<br> 20g3 + 24g2 – 15g – 18

abruzzese [7]

First, put parenthesis around the first two numbers and the last two numbers.
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis.
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis.
(5g+6) (4g²-3)
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.
