Mona can travel 500km if she wants to spend at most $250.
What is the cost function?
The functional relationship between cost and output is referred to as the "cost function." It examines the cost behavior at various output levels under the assumption of constant technology. It can be stated as follows: C = f(Q) (where Q = Quantum of output and C = Cost of production).
Here, we have
Given:
Mona rents a car for $175 a week, plus $0.15 a mile.
We have to find out how far can she travel if she wants to spend at most $250.
We set up a
cost function C(m), where m is the number of miles:
C(m) = Cost per mile * m + car rent
C(m) = 0.15m + 175
The problem asks for m when C(m) = 250
0.15m + 175 = 250
0.15m = 250 - 175
0.15m = 75
m = 75/0.15
m = 500
Hence, Mona can travel 500km if she wants to spend at most $250.

The percentage of puffin eggs that hatch given in decimal form by the quadratic function, f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61, gives;
a. At 51 °F, 1.5% of the eggs will hatch
b. The temperature at which the maximum percentage of puffin eggs will hatch is approximately 49.5 °F
The maximum percentage of eggs that hatch is approximately 91.8 %
What is a quadratic function?A quadratic function is a polynomial of the second degree (degree 2) such that the highest power of the variables in a quadratic function is 2
The quadratic function is presented as follows;
f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61
Where;
f(x) = The percentage of the eggs that hatch
x = The mean sea surface temperature of the area in degrees Fahrenheit
a. The percentage of the eggs that will hatch at 51° is therefore;
f(51) = -0.379•(51 - 46)² + 2.62•(51 - 46) - 3.61 = 0.015
The percentage of the eggs that hatch at 51° d is f(51) = 0.015 × 100% = 1.5%
b. The temperature for which the percentage of hatched puffin eggs is a maximum, is given by the maximum value of the quadratic function as follows;
At the maximum value of the quadratic function, f(x) = a•x² + b•x + c, we have;
x = -b/(2•a)
Therefore, where we have;
f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61
At the maximum value;
x - 46 = -2.62/(2×(-0.379)) = 1310/379
x = 46 + 1310/379 ≈ 49.5°Which gives;
The mean temperature at which the percentage of hatched puffin eggs is a maximum is approximately 49.5°Second part;
The percentage of eggs that hatch at the temperature that gives the maximum percentage of eggs is the maximum percentage of eggs, which is found as follows;
f(46 + 1310/379) = -0.379•(1310/379)² + 2.62•(1310/379) - 3.61 ≈ 0.9179683

The function is decreasing in the interval (3, ∞).
Explain about the decreasing function?You must first compute the derivative, then make it equal to 0, and then determine whether zero values your function is negative between in order to determine whether a function is decreasing. In order to determine once the function is negative and, consequently, decreasing, test values from all sides of these.f(x) = -x² + 6x - 4
Differentiate the equation with respect to 'x'.
f'(x) = -2x + 6
Put f'(x) = 0
-2x + 6 = 0
x = 6/2
x = 3 (critical point)
Now, write the function as:

Jim and Lillian are painting a

paint will they need to buy?
Answers
Jim and Lillian are painting a wall that is 15 ft wide and 9 feet tall and they will need to buy $ 135x of paint to paint the whole wall, where "x" is the cost of painting per square feet of the wall.
To solve this question, we will move ahead with a very direct approach of problem solving which is, step-by-step formulation.
First, we will calculate the area of the wall to be painted by using the formula to calculate the area of a rectangle which goes as
\((l*b)\) sq. feet where, "l" is the length or height of the rectangle and "b" is the breadth or width of it.
Then, we will just multiply the calculated area with the rate of painting per unit.
Here, as per data provided in the question statement, the wall to be painted is 15 ft wide and 9 feet tall, i.e., (l = 15) and (b = 9).
Therefore, area of the wall = \((15*9)=135\) square feet.
And since, no rate of painting is provided, let us assume that the rate of painting per square feet is $ x, then, amount of paint to be purchased to paint the wall will be \((135*x)=$135x\) Dollars.

Find the mean,mode,and median time
Answers
Answer:
Mean: \(\bar x = 40.61\)
\(Median =40.2\)
\(Mode = 43.4\)
Step-by-step explanation:
Given
See attachment for data
Solving (a): The mean
Mean is calculated as:
\(\bar x = \frac{\sum x}{n}\)
From the attached:
\(n = 14\)
So, the mean is:
\(\bar x = \frac{43.4+43.4+43.4+43.1+43.2+40.2+40.2+40.1+40.3+39.44+39.17+38.03+38.19+36.45}{14}\)
\(\bar x = \frac{568.58}{14}\)
\(\bar x = 40.61\)
Solving (b): The median
\(n = 14\); this is an even number. So, the median is:
\(Median = \frac{1}{2}(n+1)\)
\(Median = \frac{1}{2}(14+1)\)
\(Median = \frac{1}{2}(15)\)
\(Median = 7.5th\)
This implies that the median is the average of the 7th and 8th item.
Next, is to order the data (in ascending order): 36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.
The 7th and 8th items are: 40.2 and 40.2
The median is:
\(Median = \frac{1}{2}(40.2 + 40.2)\)
\(Median = \frac{1}{2}*80.4\)
\(Median =40.2\)
Solving (c): The mode
43.4 has the highest number of occurrence.
So:
\(Mode = 43.4\)

Answer:
The hand moved \(\bf \frac{3}{4}\) of a complete turn.
Step-by-step explanation:
The hand moved from 3 to 12, that is, it moved:
12 - 3 = 9 hours
In a clock, 12 hours represent a complete turn.
∴ Using the unitary method:
12 hours ⇒ 1 turn
1 hour ⇒ \(\frac{1}{12}\) turns
9 hours ⇒ \(\frac{1}{12}\) × 9 = \(\frac{9}{12}\)
= \(\bf \frac{3}{4}\) turns (simplified)
∴ The hand moved \(\bf \frac{3}{4}\) of a complete turn.
The answer is \(\boxed{\frac{3}{4}}\).
To find the fraction of a complete turn it moved in this case, take the ratio between hours covered between 3 and 12, and the hours covered in a complete turn.
Hours covered between 3 and 12 : 12 - 3 = 9Hours covered in a complete turn = 12Fraction of a complete turn it moved : 9/12 = 3/40

Therefore , the solution of the given problem of equation comes out to be the points (3,-7) and (-2,9) has a slope of 0.3125.
What is an equation?Variable words are widely used in complex algorithms to show consistency between two contradictory claims. Academic expressions called equations are used to show the equality of various academic figures. Think about the information that y + 7 provides. When paired with construct y + 7, elevating results in b + 7 in this circumstance rather than another method that may divide 12 equal two halves.
Here,
We must first establish the slope of the original line in order to determine the slope of a line perpendicular to another line. Using the slope formula, we can utilise the two provided locations to determine the slope:
=> y2 - y1 = slope = (change in y) / (change in x) (x2 - x1)
Using the values 3,-7, and 2,9, we obtain:
=> slope = (9 - (-7)) / (-2 - 3) = 16 / (-5) = -3.2
Hence, the original line has a slope of -3.2.
=> -1 / original slope is the perpendicular slope.
=> Slope perpendicular = -1 / (-3.2)
=> slope perpendicular = 0.3125
As a result, a line that passes through the points (3,-7) and (-2,9) has a slope of 0.3125.

Answers
The probability P(X=2, Y+Z ≤ 3) is 13. Random variables are variables in probability theory that represent the outcomes of a random experiment or event.
To find the probability P(X=2, Y+Z ≤ 3), we need to sum up the joint probabilities of all possible combinations of X=2, Y, and Z that satisfy the condition Y+Z ≤ 3.
Step 1: List all the possible combinations of X=2, Y, and Z that satisfy Y+Z ≤ 3:
X=2, Y=1, Z=1
X=2, Y=1, Z=2
X=2, Y=2, Z=1
Step 2: Calculate the joint probability for each combination:
For X=2, Y=1, Z=1:
f(2, 1, 1) = (2+1) * 1 = 3
For X=2, Y=1, Z=2:
f(2, 1, 2) = (2+1) * 2 = 6
For X=2, Y=2, Z=1:
f(2, 2, 1) = (2+2) * 1 = 4
Step 3: Sum up the joint probabilities:
P(X=2, Y+Z ≤ 3) = f(2, 1, 1) + f(2, 1, 2) + f(2, 2, 1) = 3 + 6 + 4 = 13

Today the weather station announced that there is a 20% chance of the weather being wet. a) What is the probability that there will be an accident on Highway 48 today? b) Suppose you have been working non-stop in the emergency room for the last 24 hours and have barely had time to eat, let alone, look out the window! An accident victim comes in and they tell you the accident happened on Highway 48. What is the probability that the weather today was wet?
Answers
a) The probability that there will be an accident on Highway 48 today is 0.36%.
b) The probability that the weather today was wet given that there was an accident on Highway 48 is approximately 55.56%.
a) To find the probability that there will be an accident on Highway 48 today, we need to consider both the probability of an accident when it's dry and when it's wet, and the probability of each type of weather. We can use the formula: P(A) = P(A|B) × P(B) + P(A|B') × P(B'), where A represents an accident, B represents wet weather, and B' represents dry weather.
P(A) = P(Accident|Wet) × P(Wet) + P(Accident|Dry) * P(Dry)
P(A) = (0.01) × (0.2) + (0.002) × (0.8)
P(A) = 0.002 + 0.0016
P(A) = 0.0036
b) To find the probability that the weather was wet given that there was an accident on Highway 48, we can use Bayes' theorem: P(B|A) = (P(A|B) × P(B)) / P(A)
P(Wet|Accident) = (P(Accident|Wet) × P(Wet)) / P(Accident)
P(Wet|Accident) = (0.01 × 0.2) / 0.0036
P(Wet|Accident) = 0.002 / 0.0036
P(Wet|Accident) = 0.5556

Is this dilation a reduction or an enlargement
Answers
Answer:
Step-by-step explanation:
A dilation maintains the shape of a figure but changes its size.
A reduction would mean the new figure will be a smaller version of the original.
An enlargement would mean the new figure will be a bigger version of the original.
This particular question doesn’t include a photo so depending on these definitions, one can easily identify the correct answer.
Answer:
In geometry, a dilation is a transformation that changes the size of a figure while keeping its shape the same. Imagine taking a picture of a shape and then making it bigger or smaller without changing its proportions or angles.
If a dilation makes the figure smaller than the original, we call it a reduction. This means that the new figure is a scaled-down version of the original. Conversely, if a dilation makes the figure larger, we call it an enlargement. In this case, the new figure is a scaled-up version of the original.
So, to summarize, dilations can change the size of a figure while preserving its shape, and we can describe the resulting figure as either a reduction or an enlargement depending on whether it is smaller or larger than the original.

Answers
The probability that a Covid-19 test for a person not showing Covid-19 symptoms is positive is 0.0847.
Here is how we can find the probability for each part of the question provided above:
a) We have, The percentage of positively tested Covid-19 cases showing symptoms = 75%The percentage of negatively tested Covid-19 cases showing symptoms = 10%Total percentage of Covid-19 tests that are positive = 25%We can calculate the probability that a randomly tested person is showing Covid-19 symptoms as follows: Let S be the event that a person is showing Covid-19 symptoms .Let P be the event that a Covid-19 test is positive. Then, P(S) = P(S ∩ P) + P(S ∩ P') [From law of total probability]where P' is the complement event of P. Then, 0.25 = P(P) + P(S ∩ P')/P(P')Now, from the given data, we have: P(S ∩ P) = 0.75 × 0.25 = 0.1875P(S ∩ P') = 0.10 × 0.75 + 0.90 × 0.75 × 0.75 = 0.6680P(P) = 0.25P(P') = 0.75Therefore, substituting the values in the equation we get,P(S) = 0.2625Thus, the probability that a randomly tested person is showing Covid-19 symptoms is 0.2625.b) We need to find the probability that the Covid-19 test for a person showing Covid-19 symptoms is positive. Let us denote this event as P. Then,P(P|S) = P(P ∩ S) / P(S) [From Bayes' theorem]Now, from the given data, we have:P(S) = 0.2625P(S ∩ P) = 0.75 × 0.25 = 0.1875Therefore, substituting the values in the equation we get,P(P|S) = 0.7143Thus, the probability that a Covid-19 test for a person showing Covid-19 symptoms is positive is 0.7143.c) We need to find the probability that the Covid-19 test for a person not showing Covid-19 symptoms is positive. Let us denote this event as P.

Multiplying big numbers will give significantly bigger results then multiplying smaller numbers then adding them. 14 + 12 = 26 & 8 + 12 = 20. 14 x 12 = 68 & 8 x 12 = 96. 96 + 168 is alot less then 26 * 20 so that is why larry is wrong

Answer:
x= -8 ,y =-3
Step-by-step explanation:
-3x +4y =12.......(i)
2x+2y=-22
x+y =-11
x= -11-y.....(ii)
now put this value of x in (i)
-3(-11-y) +4y =12
33 +3y +4y =12
7y = -21
y = -3
Now put value of y back in (ii)
x = -11 --3
x= -8

Suppose X = 6. If X changes to 27, what percentage change is this? Please round your answer to 2 decimal places.
Answers
The percentage change from 6 to 27 is approximately 350.00%.
To calculate the percentage change, we can use the following formula:
Percentage Change = ((New Value - Old Value) / Old Value) * 100
Given:
Old Value (X) = 6
New Value = 27
Using the formula, we have:
Percentage Change = ((27 - 6) / 6) * 100
Calculating this expression, we find:
Percentage Change ≈ 350.00
Rounding the percentage change to two decimal places, we have:
Percentage Change ≈ 350.00%
Therefore, the percentage change from 6 to 27 is approximately 350.00%.

Subjects who participate in a study of patients with inflammatory bowel disease are described as the:a. accessible population. b. element. c. sample. d. target population.
Answers
The target population is the population of interest that researchers aim to generalize their findings to.
The correct answer is c. sample.
In a research study, the population of interest is often too large or too difficult to access entirely. Therefore, researchers select a representative subset of the population to study, which is called a sample. In this case, patients with inflammatory bowel disease are the population of interest, and those who participate in the study are the sample.
The accessible population refers to the portion of the population that is accessible to the researcher. For example, if a researcher is studying the prevalence of a disease in a certain region, the accessible population would be the individuals living in that region.
An element refers to a single member of the population or sample.
The target population is the population of interest that researchers aim to generalize their findings to.
