What is the selling price?

The price you will pay to purchase a share or any other commodity is known as the "buy" or "bid" price. The price you will receive when you sell that share or commodity is the "sell" or "ask" price.

Here, we have

Given: Tom and John are engaged in buying and selling certain products A and B. Tom buys 5 of product A but sells twice as much of product B. John on the other hand sells three times what Tom bought of product A and buys 13 of product B. At the end of the business day, John banks Ksh 110,000/- while Tom banks Ksh 230,000.

Let's assume that the cost price for both products A and B is "x", and the selling price for both products A and B is "y". We can use this information to set up two equations, one for Tom and one for John, that relate the costs and profits for the two products:

Tom: 5x - 2(5y) = P₁

John: 3(5x) - 13x = P₂

where  P₁ and P₂ are the profits made by Tom and John, respectively.

We know that at the end of the business day, John banks Ksh 110,000/- while Tom banks Ksh

230,000. So we can write:

P₁ = 230,000 - 5x

 P₂ = 110,000 - 18x

Substituting these values into the equations for Tom and John, we get:

5x - 2(5y) = 230.000 - 5x

Simplifying these equations, we get:

10x - 10y = 230,000

2x = 110,000

x = 55,000

Substituting this value back into the first equation, we can solve for y:

10(55,000) - 10y = 230,000

Simplifying this equation, we get:

y = 32,000

Hence, the price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.

Harris should expect to spin a sum that is 10 or greater than 100 times.

Part A:

To predict the number of times Harris will spin a sum less than 10, we need to find the probability of getting a sum less than 10 and multiply it by the total number of spins, which is 500.

The possible outcomes of the first spinner are 1, 2, and 3, and the possible outcomes of the second spinner are 4, 5, 6, 7, and 8.

The minimum sum we can get is 1+4=5, and the maximum sum we can get is 3+8=11.

To get a sum less than 10, we can get:

1+4=5

1+5=6

1+6=7

1+7=8

1+8=9

2+4=6

2+5=7

2+6=8

2+7=9

3+4=7

3+5=8

3+6=9

There are 12 possible outcomes that result in a sum less than 10. So the probability of getting a sum less than 10 is 12/15, or 4/5.

To find the number of times Harris will spin a sum less than 10, we can use the equation:

probability of getting a sum less than 10 × total number of spins = x

So the equation that can be solved to predict the number of times Harris will spin a sum less than 10 is:

C) 12/15 = x/500

Part B:

To find the number of times Harris should expect to spin a sum that is 10 or greater, we can subtract the number of times he will spin a sum less than 10 from the total number of spins:

total number of spins - number of times he will spin a sum less than 10 = number of times he should expect to spin a sum that is 10 or greater

Substituting the values, we get:

500 - (12/15 × 500) = 500 - 400 = 100

So Harris should expect to spin a sum that is 10 or greater than 100 times.

c. W (x) + 10

Expressions are statements in mathematics that include variables, numbers, or both, as well as at least two terms connected by an operator. Addition, subtraction, multiplication, and division are examples of mathematical operations.

The equation x + y, which combines the terms x and y with an addition operator, serves as an illustration. Expressions can be classified into two categories in mathematics: algebraic expressions, which also contain variables, and numerical expressions, which only contain numbers.

W(x) gives the temperature W in the apartment x hours after midnight.

H(x) gives the temperature H x hours after midnight when it is hot outside.

When it is hot outside, the owner changes the settings to be exactly 10 degrees warmer than W.

So,

H (x) = W(x) + 10

If W (6.5) =75, then

H (6.5) =W (6.5) + 10

= 75+10

= 85

If W (2) = 60, then

H (2) = W (2) + 10

= 60+ 10

= 70

Thus, infants are deemed preterm if they arrive on or before 240 days (rounded to the next integer).

The study of chance and uncertainty is covered in the mathematical field of probability. It is a way to gauge how likely something is to happen. Probability can be expressed as a number between 0 and 1, with 0 indicating that an occurrence is impossible, and 1 indicating that an event is certain. Probability is frequently employed in real-world situations to forecast the results of random occurrences like tossing a coin, rolling a die, or drawing cards from a deck. The probability of an occurrence is estimated by dividing the number of possible outcomes by the number of possible ways the event could occur.

a. We need to locate the region to the right of 307 under the normal distribution curve in order to determine the likelihood that a pregnancy would last 307 days or longer.

By standardizing the value of 307, we may make use of the standard normal distribution:

(X - mu) / sigma = z

z = (307 - 268) / 15\sz = 2.6

A basic normal distribution table or calculator can be used to determine that a z-score larger than 2.6 has a probability of about 0.0047.

Thus, the likelihood of a pregnancy lasting at least 307 days is roughly 0.0047, or 0.47%.

b. We must determine the gestational period that sets the lowest 3% of pregnancies apart from the others. The value with a cumulative probability of 0.03 to its left is this one.

The z-score for a cumulative probability of 0.03 can be calculated using a conventional normal distribution table or calculator. It is roughly -1.88.

To determine the corresponding length of pregnancy, we can apply the z-score formula:

z = (x - mu)/sigma -1.88 = (x - 268)/15 -28.2 = x - 268 x = 239.8

The required  average number of people completing voting at any given time as per given 55 people per hour is equals to 27.5.

Average throughput voting facility process = 55 people per hour,

Calculate the average processing time per person ,

⇒ Processing time per person = 1 hour / 55 people

⇒ Processing time per person = 0.01818 hours/person

Average time taken by each person to complete the voting process = 30 minutes  

Convert this to hours by dividing by 60,

⇒ Flow time per person = 30 minutes / 60

⇒ Flow time per person = 0.5 hours/person

Now,

Average number of people in the voting facility using Little's Law,

which states that the average number of items in a system is equal to the average throughput multiplied by the average flow time.

⇒ Average number of people in facility = Average throughput x Average flow time

⇒ Average number of people in facility = 55 people/hour x 0.5 hours/person

⇒ Average number of people in facility = 27.5 people

Therefore, on average there are 27.5 people in the voting facility at any given time.

Inductive logic, also known as induction, is a type of reasoning that involves drawing general conclusions based on specific observations or examples.

In inductive logic, a sample is considered representative of the population from which it is taken if it possesses the following two characteristics:

Randomness: The sample should be selected randomly from the population. This means that every individual in the population should have an equal chance of being selected for the sample. A random sample helps to reduce the potential for bias in the selection process.

Size: The sample size should be large enough to accurately represent the population. A larger sample size helps to reduce the impact of chance variation and provides a more accurate estimate of the characteristics of the population.

Given a solution containing 30 mg of medication per 3 mL, you need to determine how many mL makeup 15 mg of medication. By setting up a proportion, it can be calculated that 1.5 mL should be administered per dose.

To solve this problem, we need to determine how many milliliters correspond to the required dose of medication (15 mg). Given that the pharmacy dispensed a solution containing 30 mg of medication per 3 mL, we can construct a proportion to find the needed milliliter amount.

30 mg/3 ml = 15 mg/x ml

To solve this equation for 'x', multiply both sides by 'x' and then divide by 30 mg to isolate 'x':

x = (15 mg * 3 ml) / 30 mg

Upon completing this calculation, you find that x equals 1.5 ml. Therefore, you would administer 1.5 mL of the medication per dose.

Step-by-step explanation:

None explains the use of 0.5 for the most conservative sample size. Thus E is the correct one.

A confidence interval is a range of values that is likely to contain the true population parameter, and a wider confidence interval allows for a greater chance of accurately capturing the true population parameter.

The use of 0.5 as an estimate of the sample proportion is most conservative because it produces the widest confidence interval.

A larger sample size is generally used when the confidence interval is wider, as it improves the precision of the estimate.

Using 0.5 as the estimated proportion will produce the widest confidence interval and thus, a larger sample size.

Answer: Let x be the number of gallons of the first brand (30% pure antifreeze) that needs to be mixed, and let y be the number of gallons of the second brand (80% pure antifreeze) that needs to be mixed. We want to find the values of x and y that satisfy the following conditions:

The total amount of antifreeze mixed is 150 gallons: x + y = 150

The resulting mixture is 40% pure antifreeze: 0.3x + 0.8y = 0.4(150)

We have two equations with two unknowns, so we can solve for x and y. We'll use the first equation to solve for y in terms of x:

y = 150 - x

Substituting this expression into the second equation gives:

0.3x + 0.8(150 - x) = 60

Simplifying and solving for x:

0.3x + 120 - 0.8x = 60

-0.5x = -60

x = 120

Substituting this value back into y = 150 - x gives:

y = 150 - 120 = 30

Therefore, we need to mix 120 gallons of the first brand and 30 gallons of the second brand to obtain 150 gallons of a mixture that contains 40% pure antifreeze.
