Thousands of people are going to a Grateful dead concert in Pauley Pavillion at UCLA. They park their the foot cars on several of the long streets near the arena.

In the long run, what fraction of the street is covered with cars

Answers

This question is incomplete, the complete question is;

Thousands of people are going to a Grateful dead concert in Pauley Pavilion at UCLA. They park their 10 foot cars on several of the long streets near the arena. There are no lines to tell the drivers where to park, so they park at random locations, and end up leaving spacings between the cars that are independent and uniform on ( 0, 10 ). In the long run, what fraction of the street is covered with cars?.

Answer:

in the long run, the fraction of street that will be covered with cars is 0.6667

Step-by-step explanation:

 given the data in the question;

the gaps between two cars follows uniformly ) 0, 10 )

therefore in the long run, average gap will be;

⇒ (0 + 10) / 2 = 10 / 2 = 5 feet

meaning that, in the long run a single car will occupy;

⇒ length of car + gap

⇒ 10 + 5 = 15 feet

∴ the fraction of road covered with cars will be;

⇒ length of car / space or length of road occupied by one car

⇒ 10 / 15

0.6667

Therefore, in the long run, the fraction of street that will be covered with cars is 0.6667


If the diameter of a circle is 8, then what is its area and its circumference?

Answers

Answer:

A≈50.27

Diameter = 8

Using the formulas

A=πr2

Solving forA

A=1

4πd2=1

4·π·82≈50.26548

Answer:

I think it would be 50.24

Step-by-step explanation:

Here's what I did:

1. Diameter = 8 so radius = 4

2. 4 to the second power is 16

3. 16 × 3.14 = 50.24

I'm not sure if what I did is correct, but I hope this helps! :)

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.

Answers

Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 (Work the operations in parentheses first.)

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (Divide 50.24 by 2. Do the same for 112.)

25.12 + 56 (Add 25.12 & 56.)

81.12 cm²

The area of the figure is 81.12 cm².

Answers

Answer:

Slope = 5/3

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

m =  5/3

Answer:

5/3

Step-by-step explanation:

Hello, to find the slope from two given points, you use this formula- y2-y1/x2-x1. In this problem, 9 would be y2, -6 would be y1, 6 would be x2, and -3 would be x1. The equation should look like this:

9-(-6)/6-(-3)

Since both are negatives, you would add it like this:

9+6/6+3= 15/9

Now, you need to simplify this fraction which is 5/3.
