Answer:

$12.00

Step-by-step explanation:

We know that 1 pound = 16 oz.  Thus, we can create a proportion to find how many ounces (x) is 2.5 pounds:

[tex]\frac{1}{16}=\frac{2.5}{x}\\ x=(2.5*16)\\ x=40[/tex]

Since 2.5 pounds = 40 oz, we can now multiply 40 by 0.30 to find the price of 40 ounces of peacans priced at $0.30/ounce:

40 * 0.30 = $12.00

The linear equation that models the number of pages that he reads is:

y = 56*x

So we know that Mark reads 42 pages every 3/4 of an hour, and we want to write an equation that models the number of pages y that mark reads in x hours, to do so we needto get the unit rate.

Take the quotient between the number of pages and the time above to get:

u = (42 pages)/(3/4 hours) = 56 pages per hour.

Then the number of pages that he can read in x hours is modeled by the linear equation:

y = 56*x

As x approaches negative infinity (i.e., x → -∞), the term -4x³ dominates the expression and becomes increasingly positive. Therefore, the end behaviour of f(x) as x → -∞ is f(x) → +∞.

The behavior of a function refers to how the function changes or behaves as the input values (usually denoted as x) approach certain values, typically positive infinity, negative infinity, or a critical point.

To determine the end behaviour of the function f(x), we need to examine the highest-degree term of the polynomial, which is -4x³.

As x approaches positive infinity (i.e., x → ∞), the term -4x³ dominates the expression and becomes increasingly negative. Therefore, the end behaviour of f(x) as x → ∞ is f(x) → -∞.

Similarly, as x approaches negative infinity (i.e., x → -∞), the term -4x³ dominates the expression and becomes increasingly positive. Therefore, the end behaviour of f(x) as x → -∞ is f(x) → +∞.

Yes, this is an example of bias, specifically, response bias.

Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain. Probability can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. It is an important concept in many fields, including mathematics, statistics, physics, and engineering, and is used to make predictions, analyze data, and make decisions under uncertainty.

Here,

Response bias occurs when the answers given by respondents in a survey do not accurately reflect their true opinions or beliefs. In this case, the question asked by the soft drink company is leading and suggestive, and it suggests that the company's product is superior to its rival's product. By framing the question in this way, the soft drink company is more likely to receive a positive response from respondents, even if they do not actually believe that the company's product is better than its rival's product.

Angles, which express how much of a turn or rotation there is between two rays or line segments, are measured in degrees or radians. They are frequently employed in physics, engineering, geometry, trigonometry, and other disciplines.

given

The characteristics of parallel lines and transversals allow us to determine that:

Interior angles on the same side of the transversal: 1 + 2 = 180°; 2 + 3 = 180°.

We know that (1) = 147°, thus we can apply the first equation to determine 2:

∠1 + ∠2 = 180°

147° + ∠2 = 180°

∠2 = 33°

We can apply the second equation to determine 3 now that we know 2:

∠2 + ∠3 = 180°

33° + ∠3 = 180°

∠3 = 147°

Answer:

Step-by-step explanation:

To calculate the probability of a person driving while intoxicated or having a car accident, we need to use the formula for the union of events:

P(A or B) = P(A) + P(B) - P(A and B)

where A and B are the events of driving while intoxicated and having a car accident, respectively.

Using the probabilities given in the problem, we can calculate:

P(intoxicated) = 0.32

P(accident) = 0.09

P(accident | intoxicated) = 0.15

To find P(intoxicated or accident), we first need to find P(intoxicated and accident). We can use the formula for the conditional probability as follows:

P(intoxicated and accident) = P(accident | intoxicated) x P(intoxicated)

P(intoxicated and accident) = 0.15 x 0.32 = 0.048

Now we can use the formula for the union of events:

P(intoxicated or accident) = P(intoxicated) + P(accident) - P(intoxicated and accident)

P(intoxicated or accident) = 0.32 + 0.09 - 0.048

P(intoxicated or accident) = 0.362

Therefore, the probability of a person driving while intoxicated or having a car accident is 0.362, or approximately 36.2%.

The image of the point B after the rotation by 180 degrees about point C is (0, 0)

Given that

B = (4, 4)

C = (3, 1)

The rotation rule is given as

Rotation by 180 degrees counterclockwise around vertex C

The rule of 180 degrees counterclockwise about the origin is

(x,y) = (-x,-y)

If the center of rotation is (a, b), then we have

(x,y) = (-(x - a) + b, -(y - b) + a)

So, we have

B' = (-(4 - 3) + 1, -(4 - 1) + 3)

A 95% confidence interval that the t population mean number of books  is between 9.89 and 11.11 books.

What is confidence interval ?

A confidence interval is a statistical range that provides an estimate of the likely range of values for a population parameter (such as a mean, proportion, or standard deviation) based on a sample of data. It is calculated using a specific level of confidence, which represents the probability that the true population parameter falls within the calculated range.

Confidence intervals are typically expressed as a range of values with a margin of error or standard error. The margin of error represents the amount of random variation that is expected due to sampling error, while the standard error reflects the variability of the sample data.

According to the question:
C. There is 95% confidence that the population mean number of books read is between a lower bound of approximately 9.89 books and an upper bound of approximately 11.11 books.

To construct the confidence interval, we can use the formula:

The quadratic equation is in the standard form: ax^2 + bx + c = 0. To use the quadratic formula to find the solutions, we need to identify the values of a, b, and c in the equation:

a is the coefficient of the x^2 term, which is -3 in this case.

b is the coefficient of the x term, which is -5 in this case.

c is the constant term, which is 9 in this case.

Therefore, the values of a, b, and c in the quadratic equation -3x^2 - 5x + 9 = 0 are:

a = -3

b = -5

c = 9

Answer:

Let x be the cost of 1 kg of mushrooms and y be the cost of 1 kg of turnips.

From the given information, we can form two equations:

2x + 2.5y = 8.55 (Equation 1)

3x + 4y = 13.10 (Equation 2)

To solve for x and y, we can use the method of elimination. Multiplying Equation 1 by 4 and Equation 2 by -2, we get:

8x + 10y = 34.20 (Equation 3)

-6x - 8y = -26.20 (Equation 4)

Adding Equation 3 and Equation 4, we get:

2x + 2y = 8

Simplifying this equation, we get:

x + y = 4 (Equation 5)

Now we have two equations: Equation 2 and Equation 5. We can solve for x and y using substitution or elimination. Here, we will use substitution.

From Equation 5, we can express x in terms of y as:

x = 4 - y

Substituting this expression for x into Equation 2, we get:

3(4 - y) + 4y = 13.10

Simplifying and solving for y, we get:

y = £1.50

Substituting this value for y into Equation 5, we can solve for x:

x + £1.50 = 4

x = £2.50

Therefore, the cost of 1 kg of mushrooms is £2.50 and the cost of 1 kg of turnips is £1.50.

a) The cost of 1 kg of turnips is £1.50.

b) The cost of 1 kg of mushrooms is £2.50.

To solve this linear programming problem using graphical methods, start by graphing the feasible region determined by the given constraints:

We can graph each of these inequalities by first plotting the corresponding boundary line, and then shading in the appropriate region.

Rearrange the first three inequalities to isolate y:

[tex]\boxed{\begin{aligned}2x - 3y & \leq 12\\2x - 12 & \leq 3y \\3y &\geq 2x - 12\\y& \geq \dfrac{2}{3}x-4\end{aligned}}[/tex]  [tex]\boxed{\begin{aligned}x + y & \geq 3\\y & \geq -x+3\\ \phantom{w}\\\phantom{\dfrac12}\end{aligned}}[/tex]  [tex]\boxed{\begin{aligned}3x + 4y & \geq 24\\4y & \geq -3x + 24\\y & \geq -\dfrac{3}{4}x + 6\\\phantom{w}\end{aligned}}[/tex]

Graph the inequalities.

The feasible region is the region that is shaded by all of the inequalities.

Please see the attached graph.

A bounded feasible region may be enclosed in a circle and will have both a maximum value and a minimum value for the objective function.

If a feasible region is unbounded, and the coefficients on the objective function are all positive, then an unbounded feasible region will have a minimum but no maximum, since there is no limit on how big it can get.

Therefore, as the feasible region for the given constraints is unbounded, and the coefficients of the objective function z = 3x + 4y are all positive, there is no maximum value.
