Answer:

A = 1863

Step-by-step explanation:

There are a few ways you could do this but I will do the one I know best.

Keep in mind the area is the L(enght x W(idth) = A(rea)

There are two long rectangles if you cut off the square in the middle so find the area of those two first.

31 x 23 = 713

713 x 2 = 1426 (Did this to get the area for both of them.

Now find the area of the square.

23 x 19 = 437

The you would add them all up together to get 1426 + 437 = 1863

Hope this helps :)

Answer:

1,863

Step-by-step explanation:

ok I will try to explain my answer as easy and under standable as posable.

ok what I did is the left and right side of the building I drew two lines down the middle to crate two huge rectangles on each side and one small rectangle in the middle ok. hope you understand! if you don't click the file down below.

ok after you see the file you will under stand a lot better.

ok

what I did is on the left and right triangle I did 31 tall and 23 wide. what you do I multiply the two numbers.

31 x 23 = 713

then the middle triangle is 23 wide and I did 31 - 12 to get the tall of the triangle since it did not give it to you so I got 19.

so I multiplied 23 by 19 and got 437.

so you adding all three triangles and I get 1,863 by

713 + 713 + 437 = 1,863

hope this helps

How long is the blue line in inches? Enter your final answer as a simplified fraction.

Answers

Answer:

0/12

Step-by-step explanation:

Answer:

13/15

Step-by-step explanation:

The probability of dry weather (D) = 1⁄2, rain (R) = 1⁄3 and snow (S) = 1⁄6
If it is dry the probability that someone will arrive on time is 4
/5.
If it rains the probability that someone will arrive on time is 2
/5.
If it snows the probability that someone will arrive on time is 1
/10.

Calculate the probability that somebody is late.

Answers

Answer:  9/20

=============================================================

Explanation:

Define the following events

D = weather is dryR = weather is rainyS = weather is snowyL = person is lateT = person is on time

We are given the following probabilities

P(D) = 1/2P(R) = 1/3P(S) = 1/6

Then we're further told that "if it is dry, then the probability someone will arrive on time is 4/5". We can condense that into the notation

P(T given D) = 4/5

The "given D" means that we know 100% that event D has occurred. So we're seeing how event T behaves because of D occurring. In other words P(T given D) is the same as saying "What is P(T) when we know D has happened?"

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

The instructions also mention that "If it rains, the probability someone is on time is 2/5" tells us we have the notation

P(T given R) = 2/5

And also, the probability someone is on time if it is snowy is

P(T given S) = 1/10

due to it saying "If it snows, the probability that someone will arrive on time is 1/10".

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

To recap so far, your teacher told you these three conditional probabilities

P(T given D) = 4/5P(T given R) = 2/5P(T given S) = 1/10

They are conditional due to the "given" as part of the probability. They depend on the given event happening.

Subtract each fraction from 1 and we end up with these complementary probabilities

P(L given D) = 1/5P(L given R) = 3/5P(L given S) = 9/10

I'm using the idea that P(A)+P(B) = 1, where A and B are complementary events. One or the other event must happen. Either you are on time, or you are late.

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

Recall the conditional probability formula is

P(A given B) = P(A and B)/P(B)

which rearranges to

P(A and B) = P(A given B)*P(B)

We'll use this idea to get the following

P(L and D) = P(L given D)*P(D) = (1/5)*(1/2) = 1/10P(L and R) = P(L given R)*P(R) = (3/5)*(1/3) = 1/5P(L and S) = P(L given S)*P(S) = (9/10)*(1/6) = 3/20

This means,

P(L) = P(L and D) + P(L and R) + P(L and S) ..... law of total probability

P(L) = 1/10 + 1/5 + 3/20

P(L) = 2/20 + 4/20 + 3/20

P(L) = (2+4+3)/20

P(L) = 9/20 is the probability someone is late
