A weather station on the top of a mountain reports that the temperature is currently 0 and has been falling at a constant rate of 3 degrees per hour. Find each temperature.

What was the temperature:

1 hour ago? degrees

3 hours ago? degrees

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

Explanation:

Define the following events

We are given the following probabilities

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

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

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

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

Answer:

0.92

Step-by-step explanation:

take the 8 away from 100 = 92

then divide the 92 by 100

then you have your answer 0.92

Answer:

1/8 of a cup of frosting on each cake

Step-by-step explanation:

Answer: 1/8

Step-by-step explanation:

1/2 (a+b)h

1/2 (a+16)14=132

8×14=112

14÷2=7

132-112=20

20÷7 =2.857142857

so then a= 2.86 (3sf)

Answer:

Sam gets £30 and Bethan gets £24

Step-by-step explanation:

5:4

5+4=9

£54/9= £6

£6 x 5= £30

£6 x 4 = £24

Therefore, Sam gets £30 and Bethan gets £24

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
