B.The first class’s histogram has greater spread (variability) since it is derived from a smaller number of tosses per student.

The question is asking which statement is true regarding the two histograms of -values. The first class has 250 students and they are each instructed to toss a coin 20 times. The second class has 200 students and they are told to toss a coin 40 times. The first class is tossing the coin less times than the second class, so the spread (variability) is greater for the first histogram since it is derived from a smaller number of tosses per student.

The total cost function C is  T(x) =  0.000001x³ - 0.03x² + 200x + 15,000, the total profit function P is P(x) = 0.000001x³ - 0.01x² + 50x + 15,000 and the profit for the company if 1,900 units are produced and sold each week is $80,759

The term function in math is  written as  a rule that gives value of a dependent variable that corresponds to specified values of one or more independent variables.

Here we have given that the division of Chapman Corporation manufactures a pager.

Here we also know that the weekly fixed cost for the division is $15,000, and the variable cost for producing x pagers/week in dollars is represented by the function V(x).

Then the function is written as,

=> V(x)= 0.000001x³ - 0.01x² + 50x.

Here we have given that company realizes a revenue in dollars from the sale of x pagers/week represented by the function R(x).

Then the function is written as,

=> R(x)= -0.02x² + 150x Where the value of x lies between (0<x<7500)

Then the total cost is calculated as,

=> T(x) = Total Cost + fixed cost + variable cost

Then apply the values on it, then we get,

=> T(x) = 15,000 + 0.000001x³ - 0.01x² + 50x - 0.02x² + 150x

=> T(x) =  0.000001x³ - 0.03x² + 200x + 15,000

And the total profit function is written as,

=> P(x) = 0.000001x³ - 0.03x² + 200x + 15,000 - (-0.02x² + 150x)

=> P(x) = 0.000001x³ - 0.01x² + 50x + 15,000

If the is the profit for the company if 1,900 units are produced and sold each week, then the profit is calculated as,

=> P(1900) = 0.000001(1900)³ - 0.01(1900)² + 50(1900) + 15,000

=> P(1900) = 80759

On a variable ratio schedule, reinforcement is given for the next correct response after varying numbers of responses have been made.

What is variable ?

A variable is a value or quantity that can change or take on different values in a given context or system. In mathematics and science, variables are often used to represent unknown or changing values in an equation or model. In programming, a variable is a named container or storage location that holds a value that can be modified during the execution of a program.

On a variable ratio schedule, reinforcement is given for the group of correct responses that occur after varying amounts of time have passed. This means that the reinforcement is not given after a fixed number of responses or after a fixed amount of time has passed. Instead, the reinforcement is given after a varying number of correct responses have been made, making it unpredictable for the individual or organism being reinforced. This type of schedule is often used in gambling and other situations where the reinforcement is desired to be unpredictable and maintain the individual's interest or motivation.

On a variable ratio schedule, reinforcement is given for the next correct response after varying numbers of responses have been made.

He has 255.17 more in debits than in credits. Thus, option D is correct.

Debits and credits in double-entry bookkeeping are entries made in account ledgers to reflect changes in value brought on by business transactions. A debit entry, not a credit entry, is used to show the amount of money that has been transferred into or out of an account. Value is exchanged with each transaction from credited to debited accounts.

Let's call B the amount in credit that Ignatius had, and C the amount in debits that Ignatius had during the month.

We know that the initial amount in his account was 124.82, while the final balance was 659.27.

Final amount = the initial amount + amount of credits - the amount of debits

$255.17= $255.17 (B-C)

The value that Daniela got is wrong because she should have divided through by 3 to get x instead of subtracting

We have y = 3x + b

We are to find the value of x from the equation that we have above

But first we are to take the other terms to one part of the equation so that x can stand on its own

3x = y - b

divide through the equation by 3

3x / 3 = y - b / 3

x = y - b / 3

What is a star?

A polygon, which is a form with many sides, is a type of star. In fact, five-pointed stars are categorised as decagons or polygons with ten sides, although the number of sides changes depending on the number of points on the star, such as six, ten, etc. An equilateral and equiangular polygon that self-intersects is referred to as a regular star shape or regular star polygon. It was made by connecting the vertices of a straightforward, regular, n-sided polygon to one another in a nonadjacent direction until the original vertices were once again reached.

How are stars with five points made?

All stars are formed by lines at particular angles. The basic pattern is as follows in the case of five-pointed stars, which are the most prevalent:

In the 30-60-90 triangle below, side s has a length of 4 and side q has a length of [tex]4\sqrt{3}[/tex] (Option E).

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem. The Pythagorean Theorem says (hypotenuse)²= (leg1)²+(leg2)². And the main trigonometric ratios are: sin (x) , cos  (x) and tan  (x) .

The question asks the value of sides s and q of the given right triangle. If you have the value of the hypotenuse and all angles of the triangle, you can solve this exercise by applying the trigonometric ratios. See below.

[tex]sin 30\° = \frac{opposite \; leg}{hypotenuse}\\ \\ \frac{1}{2}=\frac{s}{8} \\ \\ 2s=8\\ \\ s=4[/tex]

[tex]cos 30\° = \frac{adjacent\; leg}{hypotenuse}\\ \\ \frac{\sqrt{3} }{2}=\frac{q}{8} \\ \\ 2q=8\sqrt{3} \\ \\ q=4\sqrt{3}[/tex]

The correct answer is D. the proportion of boxes with broken glass is greater than 0.08.

The p-value is 0.001 which is less than the significance level of α = 0.01; therefore, the null hypothesis (H0: p = 0.08) can be rejected. We can conclude that there is convincing evidence that the proportion of all boxes that contain broken glass is greater than 0.08.

To calculate the p-value, we can use the formula: p-value = P(x ≥ X|H0)

Where X is the sample mean, and H0 is the null hypothesis that the proportion of boxes with broken glass is equal to 0.08.

Using this formula, we get: p-value = P(x ≥X|H0) = P(x ≥ 0.08) = 0.001

Since the p-value is less than the significance level of 0.01, the null hypothesis can be rejected and we can conclude that there is convincing evidence that the proportion of boxes with broken glass is greater than 0.08.

The cost per ounce of a container of gochujang at the market can be calculated using the equation of the line of best fit.

The line of best fit is given by the equation y = 0.14x + 1.3, where y is the cost of the container and x is the amount of sauce in the container (in ounces). To calculate the approximate cost per ounce of a container of gochujang, we can use this equation. We set y = 1, since we want the cost of one ounce of sauce. The equation of this line is y = 0.25x + 3.2, where x is the amount of sauce in the container and y is the cost of the container. To find the cost per ounce, we need to divide the y-intercept, 3.2, by the slope, 0.25. This gives us 12.8. Therefore, the approximate cost per ounce of a container of gochujang at the market is $12.8.
