The probability that it rains is about 20%.
The probability that the bus is late is about 8%.
The probability that it rains and the bus is late is about 3%.
The probability that the train is late is about 5%.
The probability that it rains and the train is late is about 1%.

what can you conclude about the rain and the students commute on the bus and train?

Answers

Answer 1

Let A= probability it rains
P(A)=0.2
Let B be the probability that the train is late = 0.05
P(B)=0.05
A and B is A∩B= the probability it rains and the bus is late =0.01
probability pf (A and B)=0.01
7) independent events are related by expression:
A∩B=P(A)*P(B)
=0.2*0.05=0.01
check :
p(A|B)=P(A∩B)÷P(B)=0.01/0.05= 0.2
the two event are independent

An 18-feet ladder is leaning against the side of a building. The angle between the ladder and the ground is 30°.
How high up on the building, from the ground, is the top of the ladder?

Answers

9514 1404 393

Answer:

9 feet

Step-by-step explanation:

The sine relation applies.

Sin = Opposite/Hypotenuse

sin(30°) = height/(18 ft)

height = (18 ft)sin(30°) = (18 ft)(1/2)

height = 9 ft

The ladder extends 9 feet up the side of the building.

a. {(-6, -5), (3, 2), (10, 8), (3, 3)}

A triangle has angle measures of 95° and 65° What is the measure of the third angle

Answers

The third angle is 20°. This is because you add the two angles you have already (95+65) and then you subtract that from 180. In simplier words: If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3rd angle.

Find the geometric mean between 28 and 32. Round to the nearest tenth if necessary.

Answers

Answer: The geometric mean is √24 * 32 = √768 = 16√3.

The geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

Let x be the geometric mean between 28 and 32

The formula for the geometric mean:

x = √(a×b)

x = √(28×32)

x = √800

x = 20√2

x = 28.284

x = 28.29

Thus, the geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.
