Elliot's walking speed was 1 mile/hour.

Elliot's walking speed can be found with the help of the given information.Distance between Elliot's house and friend's house = 3 milesTime taken to reach the friend's house + time taken to return home = 2 hours

Time taken to reach friend's house when riding = Distance/Speed

Time taken to return home when walking = Distance/Speed + 4

Let's assume Elliot's walking speed as x miles/hour.

Distance traveled while riding the bike is equal to distance traveled while walking. Therefore, using the formula for distance,

Distance = Speed × Time

We have,D/S(walking) = D/S(biking)D/x = D/(x + 4)

On cross-multiplying, we get, x(x + 4) = 3x

On solving the above equation, we get

,x² + 4x = 3x⇒ x² + x = 0⇒ x(x + 1) = 0⇒ x = 0 or x = -1

Elliot's walking speed cannot be negative or zero. Therefore, Elliot's walking speed was 1 mile/hour.

The company that offers the fastest mean downloading speed is Able Cable with a mean downloading speed of 4.0 megabits per second (Mbps). Able Cable has the fastest mean downloading speed when compared to CityNet and Tel-N-Net with means of 3.7 Mbps and 3.8 Mbps, respectively.

Mean downloading speed can be calculated by adding up all the download speeds for each provider and dividing the total by the number of providers. The downloading speeds of three providers, City Net, Able Cable, and Tel-N-Net, are given in megabits per second in the following table: Provider Download Speed(megabits per second)CityNet3.6, 3.7, 3.7, 3.6, 3.9Able Cable3.9, 3.9, 4.1, 4.0, 4.1Tel-N-Net3.9, 3.7, 4.0, 3.6, 3.8

To find which company offers the fastest mean downloading speed, we must calculate the mean (average) downloading speed of each company. We can use the following formula to calculate the mean downloading speed:mean downloading speed = (sum of download speeds) / (number of download speeds)Let's calculate the mean downloading speed of each company.CityNet:mean downloading speed = (3.6 + 3.7 + 3.7 + 3.6 + 3.9) / 5mean downloading speed = 18.5 / 5mean downloading speed = 3.7 MbpsAble Cable:mean downloading speed = (3.9 + 3.9 + 4.1 + 4.0 + 4.1) / 5mean downloading speed = 20 / 5mean downloading speed = 4.0 MbpsTel-N-Net:mean downloading speed = (3.9 + 3.7 + 4.0 + 3.6 + 3.8) / 5mean downloading speed = 18 / 5mean downloading speed = 3.6 MbpsTherefore, the company that offers the fastest mean downloading speed is Able Cable with a mean downloading speed of 4.0 Mbps. Able Cable has the fastest mean downloading speed when compared to CityNet and Tel-N-Net with means of 3.7 Mbps and 3.6 Mbps, respectively.

The probability of at least one 6 showing on any of the three dice is 91/216, which is not equal to 1/2. Therefore, the answer to the question is no, P (A1 U A2 U A3) does not equal 1/2.

The probability of an event A happening, P(A), is the number of ways that A can occur divided by the total number of possible outcomes. In this case, we want to find the probability of at least one 6 showing on any of the three dice, which is represented by P(A1 U A2 U A3).

We can use the formula P(A1 U A2 U A3) = P(A1) + P(A2) + P(A3) - P(A1 ∩ A2) - P(A1 ∩ A3) - P(A2 ∩ A3) + P(A1 ∩ A2 ∩ A3) to find the probability of at least one 6 showings.

Each die has 6 possible outcomes, so the probability of getting a 6 on any one die is 1/6. The probability of getting a 6 on two dice is (1/6)*(1/6) = 1/36, and the probability of getting a 6 on all three dice is (1/6)*(1/6)*(1/6) = 1/216.

Plugging these values into the formula, we get:

P(A1 U A2 U A3) = (1/6) + (1/6) + (1/6) - (1/36) - (1/36) - (1/36) + (1/216) = 91/216

Given:

An item was sold at a loss of 20%.

If the item is sol for Rs. 50 more then, the profit would have been 5%.

To find:

The cost price of the item.

Solution:

Let x be the cost price of the item.

The item was sold at a loss of 20%. Then selling selling price is:

\(S.P.=x-\dfrac{20}{100}x\)

\(S.P.=x-0.2x\)

\(S.P.=0.8x\)

If a the item is sold for 5% profit, then the selling price is:

\(S.P.=x+\dfrac{5}{100}x\)

\(S.P.=x+0.05x\)

\(S.P.=1.05x\)

It is given that, if the item is sol for Rs. 50 more then, the profit would have been 5%. So,

\(0.8x+50=1.05x\)

\(50=1.05x-0.8x\)

\(50=0.25x\)

Divide both sides by 0.25.

\(\dfrac{50}{0.25}=x\)

\(200=x\)

Therefore, the cost price of the item is Rs. 200.

The following parts can be answered by the concept of Combination.

a.  The total number of ways to award prizes is 100 x 99 x 98 = 970,200.

b. The total number of ways to award prizes in this scenario is 99 x 98 x 97 = 941,094.

c.  The total number of ways to award prizes in this scenario is 98 x 97 x 96 = 912,192.

d. The grand prize winner is a person holding ticket 8,11 or 23 is 3 x 99 x 98 = 29,178.

a) There are a total of 100 choices for the first prize, 99 choices for the second prize (since one person already won a prize), and 98 choices for the third prize (since two people already won prizes). So, the total number of ways to award prizes is 100 x 99 x 98 = 970,200.

b) If person holding the ticket 23 must get a prize, then there are only 99 choices for the first prize (since ticket 23 is already taken), 98 choices for the second prize, and 97 choices for the third prize. So, the total number of ways to award prizes in this scenario is 99 x 98 x 97 = 941,094.

c) If the person holding ticket 8 and the person holding ticket 11 must win prizes, then there are only 98 choices for the first prize (since tickets 8 and 11 are already taken), 97 choices for the second prize, and 96 choices for the third prize. So, the total number of ways to award prizes in this scenario is 98 x 97 x 96 = 912,192.

d) If the grand prize winner is a person holding ticket 8,11 or 23, then there are only 3 choices for the first prize (since only these three tickets are eligible for the grand prize), 99 choices for the second prize (since one person already won a prize and the grand prize winner is not eligible for the second prize), and 98 choices for the third prize (since two people already won prizes).

Answer:

m∠P = m∠Q = m∠R = 60º

Step-by-step explanation:

Because each of the sides are congruent, the angles are congruent. A triangle must add up to 180º, so when you divide 180 by 3, you get 60. Therefore, each angle is 60º.

Answer:

angle P = 60

angle Q = 60

angle R = 60

Step-by-step explanation:

The triangle in the picture is an equilateral triangle. This means that all angles are the same.

Since all triangles have the interior angle of 180, simply take 180 and divide it by 3:

⇒ 180 ÷ 3

⇒ 60

All three angles are 60 degrees

The amount of money in the account after 11 years with a $4,500 deposit at 8% annual interest compounded semiannually is $10,817.41 . (C)

To calculate this, we use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the future value, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.

1. Convert the annual interest rate to a decimal: 8% = 0.08.
2. Divide the annual interest rate by the number of compounding periods per year: 0.08/2 = 0.04.
3. Determine the total number of compounding periods: 11 years × 2 compounding periods per year = 22.
4. Use the formula: A = $4,500(1 + 0.04)^(22) = $10,817.41.

Thus, after 11 years, the account will have $10,817.41. (C)

True. Exception reports show a greater level of detail than is included in routine reports.

Exception reports are reports that help in identifying data that does not conform to expected patterns. Exception reports show information about an exception in the data set.

This helps to identify irregularities or anomalies in data or system operations.Exception reports are used to analyze system performance, monitor resource consumption, and to detect unusual activity.

This type of report is important to identify issues or errors, where the routine reports or standard reports would not provide enough detail or insight to do so.

It provides detailed information on any unusual event or anomaly that occurred beyond the usual course of events or processes.Exception reports are generated and distributed when the data is not expected or when an event occurs that is outside of what is considered typical.

For example, a financial system might generate an exception report if a transaction is entered that exceeds the maximum allowed amount. This report would show the details of the transaction and highlight the exception.

The purpose of exception reports is to provide users with a higher level of detail than they would find in routine reports. Exception reports are used to highlight significant data, which will be used for further analysis or action.
