Part A:

Each snowball costs $0.30 to make and is sold for $1.25 each.

The profit per snowball is:

P = $1.25 - $0.30 = $0.95

The profit is $0.95 per snowball

Part B:

Little brother gave away 12 snowballs. The student lost the profit of those 12 snowballs:

12 x $0.95 = $11.40

The student lost $11.40 in profits

Note: The student also lost the $0.30 for the cost to make each snowball, but it's not accounted for.

If two notebooks and five pencils cost $2.25. Four notebooks and four pencils cost $3.60 one pencil costs $0.30.

To find the cost of one pencil, we can set up a system of equations based on the given information. Let's assume the cost of one notebook is N dollars and the cost of one pencil is P dollars.

From the first statement, we can write the equation 2N + 5P = 2.25. This equation represents the cost of two notebooks and five pencils equaling $2.25.

From the second statement, we can write the equation 4N + 4P = 3.60. This equation represents the cost of four notebooks and four pencils equaling $3.60.

To solve this system of equations, we can use the method of substitution or elimination. Let's use the method of substitution.

From the first equation, we can isolate N in terms of P by rearranging it as N = (2.25 - 5P)/2.

Substituting this expression for N in the second equation, we get (4[(2.25 - 5P)/2]) + 4P = 3.60.

Simplifying and solving for P, we find that P = 0.30.

Therefore, one pencil costs $0.30.

The control chart limits (3 sigma) for the fertilizer-bag-filling machine can be computed using Table $6.1.

To compute the control chart limits (3 sigma) using Table $6.1 for the fertilizer-bag-filling machine, follow these steps:

Determine the sample size: In this problem, each sample consists of 7 observations.

Calculate the average range (R): For each sample, calculate the range by subtracting the smallest observation from the largest observation. Then, calculate the average range across all 35 samples.

Find the appropriate value from Table $6.1: Locate the row in Table $6.1 corresponding to the sample size (7) and find the factor associated with 3 sigma. This factor represents the number of standard deviations for the control limits.

Compute the control limits: Multiply the average range (R) by the factor obtained from Table $6.1 to determine the width of the control limits. Then, subtract this width from the overall average of the process data to obtain the lower control limit, and add the width to the overall average to obtain the upper control limit.

a) The probability that a laid-off worker is a man is approximately 0.439.

b) The probability that a laid-off worker is a woman is approximately 0.561.

To calculate the probabilities, we can use conditional probability. Let's denote the events as follows:

M: Worker is a man

W: Worker is a woman

L: Worker is laid off

a) We need to calculate P(M|L), which is the probability that a laid-off worker is a man. Using Bayes' theorem, we have:

P(M|L) = P(L|M) * P(M) / P(L)

We know that P(M) = 0.52 (the proportion of men in the eligible workforce), P(L|M) = 0.088 (the unemployment rate for men), and P(L) = 0.079 (the overall unemployment rate). Substituting these values, we get:

P(M|L) = (0.088 * 0.52) / 0.079 ≈ 0.439.

b) Similarly, we need to calculate P(W|L), which is the probability that a laid-off worker is a woman. Using Bayes' theorem, we have:

P(W|L) = P(L|W) * P(W) / P(L)

We know that P(W) = 1 - P(M) = 1 - 0.52 = 0.48 (the proportion of women in the eligible workforce), P(L|W) = 0.07 (the unemployment rate for women), and P(L) = 0.079 (the overall unemployment rate). Substituting these values, we get:

P(W|L) = (0.07 * 0.48) / 0.079 ≈ 0.561.

Therefore, the probability that a laid-off worker is a man is approximately 0.439, while the probability that a laid-off worker is a woman is approximately 0.561.

The value of the greater integer is 7 which is obtained by using arithmetic operations.

What are arithmetic operations?

It is claimed that all real numbers may be described by the four basic operations, sometimes known as "arithmetic operations". After division, multiplication, addition, and subtraction in mathematics are quotient, product, sum, and difference.

Let the integer be 'x'.

So, the next odd integer will be 'x + 2'.

We are given that when an integer is subtracted from 2 times the next consecutive odd integer the difference is 9.

So, from this we get

⇒2(x + 2) - x = 9

⇒2x + 4 - x = 9

⇒x + 4 = 9

⇒x = 5

The next integer will be 7.

Hence, the value of the greater integer is 7.

In summary, to find an interval of length 1 and having integer endpoints on which the function has a root, we can use a trial-and-error method to identify intervals that satisfy the given criteria. The choice of interval may depend on the specific function and there may be multiple intervals that satisfy these conditions.

To find an interval on which the function has a root, we need to consider the function's behavior and identify any potential zero crossings. An interval of length 1 with integer endpoints can be represented as [a, a+1] where a is an integer.
One approach to finding a root is to plot the function and visually identify where it crosses the x-axis. Another approach is to use algebra and solve for when the function equals zero. However, without knowing the specific function, we cannot use these methods.
Instead, we can use a trial-and-error method to identify an interval that satisfies the given criteria. For example, we can start by choosing an integer a and evaluating the function at a and a+1. If the function has opposite signs at these two endpoints, then by the Intermediate Value Theorem, the function must have at least one root in the interval [a, a+1].
We can continue this process until we find an interval that satisfies the given criteria. Note that there may be multiple intervals that satisfy these conditions, and the choice of interval may depend on the specific function.

Let's call the number of single women at the party "S" and the number of married men at the party "M". We are given that the probability that a randomly selected woman is single is S/(S+M). We want to find the fraction of people in the room who are married men, which is M/(S+M).

To find the fraction of people in the room who are married men, we can set up the equation M/(S+M) = S/(S+M) and solve for M.

M/(S+M) = S/(S+M)

M = S

Thus, the fraction of people in the room who are married men is M/(S+M) = S/(S+M) = S/2S = 1/2.

Therefore, half of the people in the room are married men.

To determine probability, divide the total number of possible outcomes by the number of possible ways an event could occur. There are differences between probability and odds. Odds are calculated by dividing a situation's likelihood of occurring by its likelihood of not occurring.

In Mathematics, a fraction defined as the part of the whole thing. For example, a pizza is divided into four equal pieces, then each piece is represented by ¼. Fractions help to distribute and judge the numbers easily and make the calculation faster.

A random number occurs in a specified distribution only when two conditions are met: The values are uniformly distributed over a defined interval or set, and it is impossible to predict future values based on past or present ones.

Let number of single women be ws and number of married women be wm (Hence number of men = wm)

We are told:  ws/wm = 2/5

fraction of men:   fm = wm/(ws+2wm)

Divide numerator and denominator by wm:   fm = 1/(ws/wm + 2), hence fm = 1/(2/5 + 2)  or fm = 5/12

The correct symbol used for a column alias containing spaces is C. " " (quotation marks).

In SQL, when we want to assign a column alias containing spaces, we enclose the alias within double quotation marks. This is done to differentiate the alias from other SQL keywords or to handle cases where the alias includes special characters, spaces, or is case-sensitive.

For example, consider the following SQL query:

SELECT column_name AS "Column Alias"

FROM table_name;

In this query, we are selecting a column named "column_name" from the table "table_name" and assigning it the alias "Column Alias" containing spaces. By enclosing the alias within double quotation marks, we indicate to the database that it should treat the entire string as a single identifier or alias.

Using other symbols such as '', ||, or // will not achieve the desired result of creating an alias with spaces. These symbols have different meanings in SQL.

'' (two single quotation marks) typically represents an empty string or a string literal in SQL.

|| (double vertical bars) is the concatenation operator in some SQL dialects, used to combine strings or values.

// (double forward slashes) is commonly used for comments in various programming languages and does not have any special meaning for column aliases in SQL.

Step-by-step explanation:

The scalar projection of a vector b onto a vector a is given by the dot product of b and the unit vector of a:

p = (b · u) * u

where u is the unit vector of a, and can be found by dividing a by its magnitude:

u = a / ||a||

The vector projection of b onto a is simply the scalar projection scaled by the unit vector:

p = p * u

For the given vectors a = ⟨-5,12⟩ and b = ⟨4,6⟩, we first find the unit vector u:

u = a / ||a|| = ⟨-5,12⟩ / ||⟨-5,12⟩|| = ⟨-5/13,12/13⟩

Next, we find the dot product of b and u:

p = (b · u) = ⟨4,6⟩ · ⟨-5/13,12/13⟩ = (4 * -5/13) + (6 * 12/13) = -20/13 + 72/13 = 52/13

So the scalar projection of b onto a is p = 52/13.

Finally, we find the vector projection by scaling the unit vector u by the scalar projection:

p = p * u = (52/13) * ⟨-5/13,12/13⟩ = ⟨-52/169,104/169⟩

So the vector projection of b onto a is p = ⟨-52/169,104/169⟩.

The graph that represents the function f(x) = 4[x] is option C.

Option C is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 4 [x]

[x] is the greatest integer function.

We see that,

f(0) = 4 [0] = 0

f(0.5) = 4 [0.5] = 4 x 0 = 0

f(x) = 0 for 0 ≤ x < 1

f(1) = 4 [1] = 4

f(1.5) = 4 [1.5] = 4 x 1 = 4

f(x) = 4 for 1 ≤ x < 2

f(2) = 4 [2] = 4 x 2 = 8

f(2.5) = 4 [2.5] = 4 x 2 = 8

f(x) = 8 for 2 ≤ x < 2

Thus,

The graph on option C has the required coordinates.

f(x) = 0 for 0 ≤ x < 1

f(x) = 4 for 1 ≤ x < 2

f(x) = 0 for 2 ≤ x < 2

It is ensured that the sample size is less than 10% of the population size when creating a confidence interval for a population proportion. This requirement is crucial because observations are more likely to be independent when the sample size is smaller than the population size. Calculating the distribution's standard deviation is impossible if this condition is not satisfied. The standard deviation of the distribution cannot be appropriately calculated if this condition is not satisfied. The confidence level will be incorrect if the standard deviation is incorrect. Population parameters are less likely to be found in a confidence interval. As a result, the capture rate will be lower than what the confidence level predicts.
