The problem states that Bert split all his cookies evenly among 4 contestants, so the total number of cookies Bert had can be found by multiplying the number of cookies each contestant received by the number of contestants:
4 * 24 = 96
Therefore, Bert had a total of 96 cookies to start with.
We can also write an equation to represent the problem, where c represents the number of cookies Bert had to start with:
c / 4 = 24
This equation states that the number of cookies Bert had divided by the number of contestants (4) is equal to the number of cookies each contestant received (24).
To solve for c, we can multiply both sides of the equation by 4:
c = 4 * 24
c = 96
So the solution confirms that Bert had 96 cookies to start with.
b. Babies who are born on or before enter your response here days are considered premature.
(Round to the nearest integer as needed.) The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. a. Find the probability of a pregnancy lasting 307 days or longer. b. If the length of pregnancy is in the lowest 3%, then the baby is premature. Find the length that separates premature babies from those who are not premature.
Thus, infants are deemed preterm if they arrive on or before 240 days (rounded to the next integer).
what is probability ?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.
given
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
Thus, infants are deemed preterm if they arrive on or before 240 days (rounded to the next integer).

State the two characteristics that tend to make a sample representative of the population from which it is taken:
The size of the sample required to be representative depends on the variability of the population and the level of precision required in the analysis.
What is Inductive logic ?
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.
Therefore, The size of the sample required to be representative depends on the variability of the population and the level of precision required in the analysis.

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.
Under the assumption that the sale prices for product A and B are the same for the two men, and the
costs prices for the products A and B are also the same for the two men, obtain the following:
a) The price for product A and the price for product B (5 marks)
b) If there was a mark up of 25% on the cost price and a discount of 15% on the sale price, how
much would each of the partners have banked at the end of the business day? (10 marks)
The price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.
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.

Randall recorded the total number of comic books in five different school libraries.
Rank the libraries from 1 having the
GREATEST total number of comic books to 5 having the LEAST total number of comic books.
Library A: 30 comic books are 2% of its total books.
Library B: 45 comic books are 5% of its total books.
Library C: 65 comic books are 2% of its total books.
Library D: 75 comic books are 10% of its total books.
Library E: 90 comic books are 3% of its total books.
To rank the libraries from 1 having the greatest total number of comic books to 5 having the least total number of comic books, we need to first calculate the total number of books in each library.
Let's start by using the information given to find the total number of books in each library:
For Library A, we know that 30 comic books are 2% of its total books. So, we can set up the following equation:
30 = 0.02x
where x is the total number of books in Library A. Solving for x, we get:
x = 1500
Therefore, Library A has a total of 1500 books.
For Library B, we know that 45 comic books are 5% of its total books. So, we can set up the following equation:
45 = 0.05x
where x is the total number of books in Library B. Solving for x, we get:
x = 900
Therefore, Library B has a total of 900 books.
For Library C, we know that 65 comic books are 2% of its total books. So, we can set up the following equation:
65 = 0.02x
where x is the total number of books in Library C. Solving for x, we get:
x = 3250
Therefore, Library C has a total of 3250 books.
For Library D, we know that 75 comic books are 10% of its total books. So, we can set up the following equation:
75 = 0.1x
where x is the total number of books in Library D. Solving for x, we get:
x = 750
Therefore, Library D has a total of 750 books.
For Library E, we know that 90 comic books are 3% of its total books. So, we can set up the following equation:
90 = 0.03x
where x is the total number of books in Library E. Solving for x, we get:
x = 3000
Therefore, Library E has a total of 3000 books.
Now that we have the total number of books in each library, we can rank them based on the number of comic books they have:
Library C: 65 comic books
Library E: 90 comic books
Library B: 45 comic books
Library A: 30 comic books
Library D: 75 comic books
Therefore, the libraries ranked from 1 having the greatest total number of comic books to 5 having the least total number of comic books are: C, E, B, A, D.

The solution of the given problem of percentage comes out to be $19,000 in 12 years, they should deposit $170.89 at the conclusion of each quarter.
What is percentage?The abbreviation "a%" is used to indicate a value or number in statistics that is expressed as a percentage of 100. Versions with "pct," "pct," or "pc" as the initials are also rare. However, the most popular method to do this is to use the percentage symbol ("%"). Additionally, both hints nor a constant ratio of every element to the overall amount exist. Since numbers commonly add up to 100, they are essentially integers.
Here,
=> [tex]FV = PMT * [(1 + r/n)^(n*t) - 1] / (r/n)[/tex].
By entering these numbers, we obtain:
[tex]= > 19000 = PMT * [(1 + 0.07/4)^(4*12) - 1] / (0.07/4)[/tex]
Upon solving for PMT, we obtain:
[tex]= > PMT = 19000 * (0.07/4) / [(1 + 0.07/4)^(4*12) - 1][/tex]
=> PMT = $174.58 (rounded to the nearest cent)
In order to have $19,000 in 12 years, the investor needs to deposit $174.58 at the conclusion of each quarter at a rate of 7% compounded quarterly.
(b) Using the same procedures as in (a), but with an interest rate of 7.2%, we arrive at:
[tex]= > 19000 = PMT * [(1 + 0.072/4)^(4*12) - 1] / (0.072/4)[/tex]
Upon solving for PMT, we obtain:
[tex]= > PMT = 19000 * (0.072/4) / [(1 + 0.072/4)^(4*12) - 1][/tex]
=> PMT = $170.89 (rounded to the nearest cent)

2x − 3y = -5 y = 2 + x The value of x in the system of equations is: x = -1. x = -3. x = 1. x = 3.
Answer: We can solve this system of equations by substituting the expression for y in terms of x from the second equation into the first equation, and then solving for x.
First, we substitute y = 2 + x from the second equation into the first equation, giving:
2x - 3(2 + x) = -5
Simplifying this expression by distributing the -3, we get:
2x - 6 - 3x = -5
Combining like terms, we get:
-x - 6 = -5
Adding 6 to both sides, we get:
-x = 1
Multiplying both sides by -1, we get:
x = -1
Therefore, the value of x in the system of equations is -1.

Define expressions?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
The expression of H in terms of W:
W (x) +10
Hence the equation:
H(x) = w(x) + 10

The derivative of the function is determined as 6πx^(π - 1) + 54.15x^(4.7).
What is the derivative of the function?
To find the derivative of f(x), we need to apply the power rule and the constant multiple rule.
Using the power rule for f(x) = 6x^π+ 9.5x^5.7 + π^5.7, we have:
f'(x) = 6πx^(π - 1) + 9.5(5.7)x^(5.7 - 1)
Next, applying the constant multiple rule, we get:
f'(x) = 6πx^(π - 1) + 54.15x^(4.7)
So the derivative of f(x) is:
f'(x) = 6πx^(π - 1) + 54.15x^(4.7)

The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.
Whether data is sorted in ascending or descending order, the median is the midway value. In this situation, the median sales amount for Company A is $7,000, which suggests that half of the sales are greater than $7,000 and half are less. The median sales amount for Business B is $6,000, which means that half of the sales are greater than $6,000 and half are less.
The median can be a useful approach to summaries a data set's core tendency. For example, we can see that Company A has a greater median sales amount than Company B, implying that Company A generates more money each sale on average. Yet, we cannot make final decisions based just on the median.

The doctor writes an order for a liquid oral medication. The order says to administer 15 mg by mouth every 4 hours as needed for sorel throat. Pharmacy dispenses you with 30 mg/3ml. How many ml will you administer per dose?
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.
Explanation: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.

To administer 15 mg of a liquid oral medication given a concentration of 30 mg/3 mL, you will need to administer 1.5 mL per dose.
Explanation:To calculate the mL of the liquid oral medication to administer, we need to determine the amount of medication in each mL. In this case, the pharmacy has dispensed a concentration of 30 mg/3 mL, which means there is 10 mg of medication in each mL. Given that the doctor's order is for 15 mg, we can calculate the mL to administer by setting up a proportion:
10 mg/1 mL = 15 mg/x mL
Cross-multiplying, we get:
10x = 15
x = 1.5
Therefore, you will need to administer 1.5 mL per dose.

How much do we need to invest each year at a rate of 8% compounded annually so that we have a total of $600,000 saved in 25 years?
Answer:
In this problem, we have to use the formula
[tex]P= \frac{A}{(1+\frac{r}{n})^{nt} }[/tex]
A = $600,000.00
n = 1 (annually)
t = 25 years
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 per year,
Then, solve the equation for P
[tex]P= \frac{A}{(1+\frac{r}{n})^{nt} }[/tex]
[tex]P= \frac{6000000}{(1+\frac{0.8}{1})^{1*25} }[/tex]
P = $87,610.74
The principal investment required to get a total amount of $600,000.00 from compound interest at a rate of 8% per year compounded annually over 25 years is $87,610.74.
