Answer:
C(p) = 0.25p + 5
Step-by-step explanation:
$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.
m = slope, b = y-intercept
C(p) = mp + b
C(p) = 0.25p + 5
Breast-feeding mothers secrete calcium into their milk. Some of the calcium may come from their bones, so mothers may lose bone mineral. Researchers measured the percent change in mineral content of the spines of 47 mothers during three months of breast-feeding.6Here are the data:

The researchers are willing to consider these 47 women as an SRS from the population of all nursing mothers. Suppose that the percent change in this population has standard deviation ? = 2.5%. Make a stemplot of the data to verify that the data follow a Normal distribution quite closely. (Don
To create a stemplot, we first need to separate the data into "stems" and "leaves." Each stem represents the first digit(s) of each data point, while each leaf represents the last digit(s). For example, if the data point is 12.3, the stem would be 12 and the leaf would be 3.
To make a stemplot, the data should be arranged in increasing order, and then separated into stems and leaves.
STEMPLOT OF THE DATAHowever, you can use the data given and arrange it in increasing order and separate it into stems and leaves to make a stemplot. A stemplot is a good way to check if the data follow a normal distribution quite closely, the more the data is spread out and the more symmetric it is, the more likely it is to follow a normal distribution.
Also, it is important to mention that from the given data, it is not possible to conclude if the percent change in this population has standard deviation of 2.5%. This parameter can only be estimated from a sample if it follows a normal distribution which is not clear from the given data.

Step-by-step explanation:
i used mathaway, hope this helps
Answer: x=29
Step-by-step explanation: 4.2(9−x)+36=102−2.5(2x+2)
Use the distributive property to multiply 4.2 by 9−x.
37.8−4.2x+36=102−2.5(2x+2)
Add 37.8 and 36 to get 73.8.
73.8−4.2x=102−2.5(2x+2)
Use the distributive property to multiply −2.5 by 2x+2.
73.8−4.2x=102−5x−5
Subtract 5 from 102 to get 97.
73.8−4.2x=97−5x
Add 5x to both sides.
73.8−4.2x+5x=97
Combine −4.2x and 5x to get 0.8x.
73.8+0.8x=97
Subtract 73.8 from both sides.
0.8x=97−73.8
Subtract 73.8 from 97 to get 23.2.
0.8x=23.2
Divide both sides by 0.8.

consider a collection of envelopes consisting of 2 red envelopes, 1 blue envelope, 1 green envelope, and 3 yellow envelopes. if three envelopes are selected at random, without replacement, determine the probability that they are all yellow envelopes. (type an integer or a simplified fraction.)
ANSWER: The probability is 1/35.
To determine the probability of selecting all yellow envelopes, we need to calculate the ratio of favorable outcomes (selecting three yellow envelopes) to the total number of possible outcomes (selecting any three envelopes without replacement).
The total number of envelopes is 2 red + 1 blue + 1 green + 3 yellow = 7 envelopes.
The number of ways to choose three yellow envelopes from the collection is given by the combination formula:
C(3, 3) = 1
The number of ways to choose any three envelopes from the collection is given by:
C(7, 3) = 7! / (3! * (7 - 3)!) = 7! / (3! * 4!) = (7 * 6 * 5) / (3 * 2 * 1) = 35
Therefore, the probability of selecting all yellow envelopes is:
P(all yellow) = favorable outcomes / total outcomes = 1 / 35
The probability is therefore 1/35.

let m be the number of five-element subsets that can be chosen from the set of the first 14 natural numbers so that at least two of the five numbers are consecutive. find the remainder when m is divided by 1000.
We have (123) different possibilities. Therefore, we can derive from the multiplication principle that there are 13(123) ways.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin.
The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half .
According to our question-
Let n be the maximum number of subsets of five elements that can be selected from the first 14 natural numbers,
with at least two of the five numbers being consecutive.
I have made a block of two consecutive numbers (like (1,2),(2,3),(13,14) etc.).
Now we can choose this block in 13 ways. Now we have to choose 3 numbers from the rest 12 numbers.
Hence, multiplication principle we come to know that there are 13×(123).

The point that lies on the terminal arm of an angle of rotation determines its quadrant. In each of the other quadrants, there is a point with the same reference angle as the original point.
The point that lies on the terminal arm of an angle of rotation determines the quadrant in which the angle is located. The terminal arm is the line segment starting from the origin and extending to the point on the coordinate plane that corresponds to the angle.
In each of the other quadrants, there is a point with the same reference angle as the original point. The reference angle is the acute angle formed between the terminal arm and the x-axis.
For example, if the original point lies on the terminal arm in the first quadrant, the point in the second quadrant with the same reference angle would have the same x-coordinate but a negative y-coordinate. Similarly, the point in the third quadrant with the same reference angle would have negative x and y coordinates, and the point in the fourth quadrant would have a negative x-coordinate but a positive y-coordinate.

2. A centrifugal compressor installed in an exhaust system discharges 2500 cfm (1.18 m3/s) at a compression ratio of 1.2. Determine its operating characteristics (pressure and quantity) in the blower position if atmospheric pressure is 14.5 psi (100 kPa).
The centrifugal compressor discharges 2500 cfm at a compression ratio of 1.2. We need to determine its operating characteristics (pressure and quantity) in the blower position given an atmospheric pressure of 14.5 psi (100 kPa).
To determine the operating characteristics in the blower position, we can use the compression ratio to find the discharge pressure. The compression ratio is the ratio of the discharge pressure to the suction pressure. Given that the compression ratio is 1.2, we can calculate the discharge pressure by multiplying the suction pressure (atmospheric pressure) by the compression ratio. Thus, the discharge pressure would be 1.2 times the atmospheric pressure.
Next, we can calculate the quantity of air discharged by the compressor in the blower position. The quantity of air is given as 2500 cfm (cubic feet per minute), which we can convert to m³/s by multiplying it by a conversion factor. Once we have the quantity of air, we can determine the operating characteristics in terms of pressure and quantity in the blower position.
In summary, given the compression ratio and the discharge quantity, we can calculate the discharge pressure by multiplying the compression ratio by the atmospheric pressure. Additionally, the quantity of air can be determined by converting the given discharge quantity to m³/s. These calculations will provide the operating characteristics (pressure and quantity) in the blower position for the centrifugal compressor.

The solution to the given expression 3(1/4 - 2) + |-7| is 7/4.
The expression is given as follows:
3(1/4 - 2) + |-7|
To solve the given expression, we need to follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, we need to simplify the expression inside the parentheses:
1/4 - 2 = -7/4
Next, we can simplify the expression by multiplying 3 by -7/4:
3(-7/4) = -21/4
Finally, we need to evaluate the absolute value of -7:
|-7| = 7
Substituting the values into the original expression, we get:
3(1/4 - 2) + |-7| = -21/4 + 7
Combining like terms, we get:
3(1/4 - 2) + |-7| = -21/4 + 28/4

let f be the function given by and g be the function given by . find the first four nonzero terms and the general term for the power series expansion of f(t) about t
The Taylor series formula in summation notation f(t) = Σ[n=0 to infinity] { (1/n!)f^n(a)(t-a)^n } where f^n(a) denotes the nth derivative of f(t) evaluated at t = a.
Since the functions f(t) and g(t) have not been given in the question, I cannot provide a specific answer to this question. However, I can provide a general approach to finding the power series expansion of a function about a point.
To find the power series expansion of a function f(t) about a point t = a, we can use the Taylor series formula:
f(t) = f(a) + f'(a)(t-a) + (1/2!)f''(a)(t-a)^2 + (1/3!)f'''(a)(t-a)^3 + ...
where f'(a), f''(a), f'''(a), ... are the first, second, third, and higher-order derivatives of f(t) evaluated at t = a.
To find the first four nonzero terms of the power series expansion, we can calculate the values of f(a), f'(a), f''(a), and f'''(a) at t = a, substitute them into the Taylor series formula, and simplify the resulting expression. The first four nonzero terms will be the constant term, the linear term, the quadratic term, and the cubic term.
To find the general term of the power series expansion, we can write the Taylor series formula in summation notation:
f(t) = Σ[n=0 to infinity] { (1/n!)f^n(a)(t-a)^n }
where f^n(a) denotes the nth derivative of f(t) evaluated at t = a. The general term of the power series expansion is given by the expression in the curly braces. We can use this expression to find any term in the series by plugging in the appropriate values of n and f^n(a).

Find the absolute maximum and absolute minimum value of f(x) = -12x +1 on the interval [1 , 3] (8 pts)
The absolute maximum value of f(x) = -12x + 1 on the interval [1, 3] is -11, and the absolute minimum value is -35.
To find the absolute maximum and minimum values of the function f(x)=-12x + 1 on the interval [1, 3], we need to evaluate the function at the critical points and the endpoints of the interval.
Step 1: Finding the critical points by taking the derivative of f(x) and setting it to zero:
f'(x) = -12
Setting f'(x) = 0, we find that there are no critical points since the derivative is a constant.
Step 2: Evaluating f(x) at the endpoints and the critical points (if any) within the interval [1, 3]:
f(1) = -12(1) + 1 = -11
f(3) = -12(3) + 1 = -35
Step 3: After comparing the values obtained in Step 2 to find the absolute maximum and minimum:
The absolute maximum value is -11, which occurs at x = 1.
The absolute minimum value is -35, which occurs at x = 3.
Therefore, the absolute maximum value of f(x) = -12x + 1 on the interval [1, 3] is -11, and the absolute minimum value is -35.
