Answer 1

Answer:

w(w-5)

Step-by-step explanation:

Given Width of rectangle = w

Length of rectangle is 5 less than width of rectangle = w - 5

Area of Rectangle = Length x Width = w * w-5 = w(w-5)

Answer 2

Answer:

the second answer option

Step-by-step explanation:

the area of a rectangle is

length × width

or

l × w

l = w - 5

so, when we use the second in the first equation, we get

(w - 5)×w

or

w(w - 5)

The length of the arc of the circle is 48.2 meters.

What is the length of the arc of the circle?

The arc length formula for a circle is times the radius of a circle. Arc length ( [tex]\theta[/tex] x r) is a way to express the arc length formula in radians.

The length of the arc is calculated as:-

Circumference =2πr=2π(20)=40π meters

Arc Length  = Central ∠360° × (Circumference)

Arc Length  =138360×40π

Arc length =463π ≈ 48.2 meters

Can you design a fair game? Use this worksheet to design a game whose expected value is 0. Be sure to define the rules of play. Prove that your game is fair using the expected value calculation.

Answers

The game that is  used for the scenario above in terms of fair play is  using a balloon. Here, the player will hit the balloon.

What is the scenario under the balloon game?

The rule of play are:

This is a classic game with simple rules which are:

Each player to hit the balloon up and it bonce into the air but when one should not allow it to touch the ground.,Players would be tied together in twos and they will juggle a lot of balloon and it have to be more than 1 balloon with one of their hands tied to their back.

A scenario of the worksheet game whose expected value is 0 is given below:

Assume that it costs about $1 for a player to play the billon game and as such, if  the player hits a balloon, they will be given $3. what can you say. Can you say that it this game is fair or not? and who has the biggest advantage.

Solution

Note that a  game is ”fair” if the expected value is said to be 0. When a player is said to hits a balloon, their net profit often increase by $4.  So when the player do not hit a balloon, it drops to $1.

(4)(0.313) + (-1)(0.313)

= 0.939 approximately

Thus, the expected value is $0.939 which tells that the game is fair.

A radio telescope has a parabolic surface, as shown below.
A parabola opening up with vertex at the origin is graphed on the coordinate plane. The height of the parabola from top to bottom is 1 meter, and its width from left to right is 20 meters.
If the telescope is 1 m deep and 20 m wide, how far is the focus from the vertex?

Answers

The height of the telescope of 1 meter and width of 20 meters gives a distance of the focus from the vertex of 25 meters.

Which method can be used to find the distance between the focus and vertex?

Given that the vertex is at the origin, we have;

(h, k) = (0, 0)

The equation of a parabola is presented as follows;

(x - h)² = 4•p•(y - k)

x² = 4•p•y

When x = 10, y = 1

Therefore;

p = 10² ÷ 4 = 25

The focus of the parabola = (h, k + p)

Which gives;

The focus of the parabola = (0, 0 + 25) = (0, 25)

The distance of the focus from the vertex is therefore;

d = 25 - 0 = 25

The distance of the focus from the vertex is 25 meters

Suppose that a classroom has 4 light bulbs. The probability that each individual light bulbs work is 0. 6. Suppose that each light bulb works independently of the other light bulbs. What is the probability that none of the 4 light bulbs work?.

Answers

Answer:

0.0256 or 16/625 or 2.56%

Step-by-step explanation:

The problem states that each light bulb operates independently of the other, so the probability doesn't change for each light bulb based on how many other light bulbs are working.

The probability of each light bulb working is 0.6 out of 1. However, we want the probability of it being broken.

1 - 0.6 = 0.4

This is the probability of one light bulb being broken. But there are 4 lightbulbs.

We can multiply 0.4 by itself 4 times, as the probability stacks.

0.4 * 0.4 * 0.4 * 0.4 = 0.0256 (Also achieved by raising 0.4 to the power of 4)

To get the percentage, multiply it by 100. 2.56%

0.4 is equal to 40% or 40/100. If you simply, that fraction is equal to 2/5

2/5 * 2/5 * 2/5 * 2/5 = 16/625 (Also achieved by raising 2/5 to the power of 4)

A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the true proportion is 0.03. If 476 are sampled, what is the probability that the sample proportion will be less than 0.04

Answers

The probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

The true proportion (p) is given to be 0.03.

Therefore, Mean (μ) = p = 0.03.

The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.

Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.

Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.

Since, we are asked to find the probability that the sample proportion is less than 0.04, we using our calculator, enter as following:

Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.

Thus, the probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

at an average rate of speed of 40 mph., at what time would William reach Town B?

Answers

The time William would arrive in town B IS 1 : 47 pm.

What time will William arrive in town B?

The first step is to determine the distance and the time of Dennis's travel.

Time = 14 hours (2 pm + 12) - 10 hours = 4 hours

Distance = time x average speed

4 x 52 = 208 miles

The second step is to determine the time of William's travel:

Distance / average speed = time

208 / 40 = 5.20 = 5 hours 12 minutes

Time William left for the trip = 10 am - 1 hour 25 minutes = 8 :35am
