2. Kyle submits a design for the contest, but his
explanation was misplaced. How can Figure A be
mapped onto Figure B? Can any other transformation be
used to map Figure A onto Figure B?
Answers
Note that in order to map A onto B, Kyle would have to dilate the given figure by a scale factor or 3.
What is a scale factor?The scale factor is a metric for figures with similar appearances but differing scales or measurements. Assume two circles appear similar but have different radii. The scale factor specifies how much larger or smaller a figure is than the original figure.
The original point of figure A which has 4 points are
(0,02)
(-1, 2)
(0, 1)
(1, 2)
Multiply all th e points by 3, and you get,
(0,02) x 3 = (0, -6) =
(-1, 2) x 3 = (-3, 6)
(0, 1) x 3 = (0, 3)
(1, 2) x3 = (3, 6)
Plotting the new values will give us the transformation (dilation) required. See the attached image.

The cost of product is birr 92 & the company is having a policy of 15% mark-up on cost,then what tha sale price will be?
Answers
The sale price of the product would be Birr 105.80.
If the cost of the product is Birr 92 and the company has a policy of 15% mark-up on the cost, then the sale price can be found by adding 15% of the cost to the cost itself.
To calculate this, we can use the formula:
Sale price = Cost + Mark-up
where the mark-up is 15% of the cost.
Mark-up = 15% of Cost = 0.15 * 92 = Birr 13.80
So, the sale price = Cost + Mark-up = 92 + 13.80 = Birr 105.80.

Player B is the most consistent, with an IQR of 2.5.
Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 5.
Answers
Answer:
To determine the best measure of variability for the data, we need to consider the type of data we are dealing with. In this case, the data is numerical and discrete, so the best measure of variability would be the range or the interquartile range (IQR).
The range is the difference between the maximum and minimum values in a dataset, while the IQR is the range of the middle 50% of the data. The IQR is less sensitive to outliers than the range, so it is often a better measure of variability.
To calculate the range and IQR for each player, we first need to order the data:
Player A: 1, 2, 2, 2, 3, 3, 3, 4, 8
Player B: 1, 1, 2, 2, 2, 3, 4, 4, 6
Player A has a range of 8 - 1 = 7, and an IQR of Q3 - Q1 = 4 - 2.5 = 1.5.
Player B has a range of 6 - 1 = 5, and an IQR of Q3 - Q1 = 4 - 1.5 = 2.5.
Therefore, Player B has a higher range and a higher IQR, indicating more variability in their performance. Player A has a lower range and a lower IQR, indicating greater consistency in their performance. Therefore, the answer is: Player A is the most consistent.
A class has seven students. What is the probability that exactly five of the students were born on a weekend?
Answers
The probability that exactly five of the students were born on a weekend is 0.1514.
Assuming that the probability of being born on a weekend is the same for all students,
we can model the number of students born on a weekend as a binomial random variable with parameters n = 7 (number of trials) and p = 2/7 (probability of success, i.e., being born on a weekend).
The probability of exactly five students being born on a weekend can be calculated using the binomial probability formula:
P(X = 5) = (7 choose 5) * (2/7)^5 * (5/7)^2
where (7 choose 5) = 7! / (5! * 2!) is the number of ways to choose 5 out of 7 students.
Evaluating this expression gives:
P(X = 5) = (7 choose 5) * (2/7)^5 * (5/7)^2
= 21 * (0.0408) * (0.1837)
= 0.1514 (rounded to four decimal places)
Therefore, the probability that exactly five of the seven students were born on a weekend is approximately 0.1514.

For y=f(x) = x^4 - 7x + 5, find dy and Δy, given x = 5 and Δx=0.2.
Answers
The derivative of y=f(x) = x⁴ - 7x + 5 is dy/dx = 4x³ - 7. For x = 5 and Δx=0.2, dy = 1.986 and Δy = -54.5504.
Given the function y = f(x) = x⁴ - 7x + 5, we can find its derivative with respect to x using the power rule of differentiation:
dy/dx = d/dx(x⁴) - d/dx(7x) + d/dx(5) = 4x³ - 7
Now, we can use the given value of x = 5 and Δx = 0.2 to find the values of dy and Δy:
dy = (4x³ - 7) dx, evaluated at x = 5 and Δx = 0.2
dy = (4(5)³ - 7) (0.2) = 198.6 × 10^(-2)
This means that a small change of 0.2 in x results in a change of about 1.986 in y.
To find Δy, we use the formula:
Δy = f(x + Δx) - f(x)
Substituting x = 5 and Δx = 0.2, we get:
Δy = ((5 + 0.2)⁴ - 7(5 + 0.2) + 5) - (5⁴ - 7(5) + 5)
Simplifying this expression gives:
Δy = (122.4496 - 177) = -54.5504
This means that a small change of 0.2 in x results in a change of about -54.5504 in y.

If the cost and revenue functions (in dollars) for producing x washing machines is given by C(x) = 10,000+ 0.7x² and R(x) =0.3x² , find the number of washing machines to produce that will maximize profit. You must use Calculus methods to receive credit
Answers
Producing 0 washing machines is not a practical solution for a company.
To maximize profit, we need to find the difference between revenue and cost functions, which gives us the profit function P(x):
P(x) = R(x) - C(x) = (0.3x²) - (10,000 + 0.7x²)
Simplify the profit function:
P(x) = -0.4x² + 10,000
Now, to maximize profit, we'll find the critical points by taking the first derivative of P(x) with respect to x:
P'(x) = dP(x)/dx = -0.8x
Set P'(x) to zero and solve for x:
-0.8x = 0
x = 0
Since the profit function P(x) is a quadratic with a negative leading coefficient, the maximum value will occur at the critical point x = 0. However, producing 0 washing machines is not a practical solution for a company.
To maximize profit while producing washing machines, the company should consider other factors beyond the given cost and revenue functions, such as market demand and production capacity.

Problem 7. (1 point) Suppose you are given a solid whose base is the circle x2 + y2 = 36 and the cross sections perpendicular to the x- axis are triangles whose height and base are equal. Find the area of the vertical cross section A at the level X = 3.
Answers
The shape formed by a solid intersecting with a plane, so the At level X = 3, the area of the vertical cross-section A is 108 square units.
To find the area of the vertical cross section A at the level X = 3, we need to find the equation of the circle when it is intersected by the plane X = 3.
First, let's find the value of y when X = 3 using the equation of the circle x^2 + y^2 = 36:
(3)^2 + y^2 = 36
9 + y^2 = 36
y^2 = 27
y = ±√27
Since we are dealing with a circle, there are two points on the circle at X = 3, which are (3, √27) and (3, -√27).
The distance between these two points will be the base of the triangle, which is also equal to its height (as given in the problem).
Base and height of the triangle: 2 * √27
Now we can find the area A of the vertical cross-section, which is a triangle with equal base and height:
A = 1/2 * base * height
A = 1/2 * (2 * √27) * (2 * √27)
A = 4 * 27
A = 108
So, the area of the vertical cross-section A at the level X = 3 is 108 square units.

My bestfriend has parents that are 11 years apart. She's 12. How old are her parents?
Answers
The younger parent is at least 1 year old, and the older parent is 23 years old.
If your best friend's parents have an age gap of 11 years, then we can assume that one of them is 11 years older than the other. Let's call the younger parent "X" years old. Then the older parent must be X + 11 years old. Since your best friend is 12 years old, we know that both of her parents are older than 12. Therefore, we can set up an equation:
X + (X + 11) > 12
Simplifying this, we get:
2X + 11 > 12
2X > 1
X > 0.5
Since X must be a whole number (you can't have half a year of age), we know that X must be at least 1. Therefore, the younger parent is at least 1 year old. Using our equation, we can find the age of the older parent:
X + 11 = 12 + 11 = 23
Therefore, the younger parent is at least 1 year old, and the older parent is 23 years old.

The sum of two numbers is 30. Determine the two numbers of their product is a maximum.
Answers
Answer:
Step-by-step explanation:
Let's call the two numbers x and y. We know that:
x + y = 30 (since the sum of the two numbers is 30)
We want to find the values of x and y that maximize their product, which is given by:
P = xy
To solve for x and y, we can use the fact that the sum of the two numbers is 30, so we can rewrite one of the numbers in terms of the other:
y = 30 - x
Substituting this into the equation for the product, we get:
P = x(30 - x)
Expanding this expression, we get:
P = 30x - x^2
To find the maximum value of P, we can take the derivative of this expression with respect to x and set it equal to zero:
dP/dx = 30 - 2x = 0
Solving for x, we get:
x = 15
So one of the numbers is x = 15, and the other is y = 30 - x = 15.
To confirm that this gives the maximum product, we can take the second derivative of P with respect to x:
d2P/dx2 = -2
Since the second derivative is negative, this means that the function P = 30x - x^2 has a maximum at x = 15.
Therefore, the two numbers are 15 and 15, and their product is maximized at P = 15 * 15 = 225.

Answers
A model car is drawn at a scale of 21 to 1. If the model car is 9. 2in. The length of the actual car in feet is approximately 0.7665 feet.
Find out the length of the actual car in feet, we need to first convert the length of the model car from inches to feet.
9.2 inches = 0.767 feet (divide by 12 since there are 12 inches in a foot)
Now, we can use the scale of 21 to 1 to find the length of the actual car in feet.
21 units on the model car = 1 unit on the actual car
So,
1 unit on the actual car = 0.767 feet / 21 = 0.0365 feet
Find the length of the actual car, we can multiply the scale ratio by the length of the model car in units:
21 units x 0.0365 feet per unit = 0.7665 feet
Therefore, the length of the actual car in feet is approximately 0.7665 feet.

The area of ΔDEF, to the nearest 10th of a square inch, is approximately 1439.1 square inches.
To find the area of ΔDEF with given values e = 67 inches, ∠F = 37°, and ∠D = 70°, follow these steps:
Find ∠E using the Triangle Sum Theorem (the sum of the angles in a triangle is always 180°).
∠E = 180° - (∠F + ∠D) = 180° - (37° + 70°) = 180° - 107° = 73°
Use the Law of Sines to find side d.
(sin ∠F) / d = (sin ∠E) / e
(sin 37°) / d = (sin 73°) / 67 inches
Solve for side d.
d = (67 inches * sin 37°) / sin 73°
d ≈ 44.7 inches
Use the formula for the area of a triangle with two sides and the included angle.
Area = 0.5 * d * e * sin ∠D
Area = 0.5 * 44.7 inches * 67 inches * sin 70°

A(11) = 5600 * (1/2)^(11/14)
A(11) ≈ 2265 grams (rounded to the nearest gram)
Find the amount of the sample remaining after 50 hours, we substitute t = 50 into the formula and evaluate:
A(50) = 5600 * (1/2)^(50/14)
A(50) ≈ 95 grams (rounded to the nearest gram)
Therefore, the amount of the sample remaining after 11 hours is approximately 2265 grams, and the amount of the sample remaining after 50 hours is approximately 95 grams.

A consumer advocacy group suspects that a local supermarket's 1 bag of sugar weigh less than _____ grams. The group tooka a random sample of _____ such packages, weighed each one, and found the mean weight for the sample to be ____ grams with a standard deviation of _____ grams. Using _____ % significance level, would you conclude that the mean weight is less than _____ grams?
Answers
A consumer advocacy group suspects that a local supermarket's 750 grams of sugar actually weigh less than 750 grams. The group took a random sample of 20 such packages, weighed each one, and found the mean weight for the sample to be 746 grams with a standard deviation of 8 grams. Using 10% significance level, would you conclude that the mean weight is less than 750 grams.
What is the hypothesis?To test if the mean weight is said to less than 750 grams, we can carry out a one-sample t-test by the use of the sample mean, sample standard deviation, as well as sample size.
The null hypothesis = 750 grams,
The alternative hypothesis= less than 750 grams.
so we need to calculate the test as:
t = (746 - 750) / (8 / √(20)) = -2.236
Next, we have to find the critical t-value for a one-tailed test with 19 degrees of freedom (so n-1 =19)
When you a t-distribution table, the critical t-value to be -1.734.
Therefore, know that -2.236 < (less than) -1.734, so you will reject the null hypothesis and say that the mean weight is less than 750 grams at a 10% significance level.

Calculate d²y/dx² y= 0.5x‐⁰.² d²y/dx²=
Answers
To calculate d²y/dx², we first need to find the first derivative of y, which is dy/dx. For y = 0.5x^-0.2, we can use the power rule of differentiation, which states that the derivative of x^n is n*x^(n-1). Therefore,
dy/dx = -0.1x^-1.2
To find the second derivative, d²y/dx², we need to differentiate dy/dx again. Using the power rule again, we get:
d²y/dx² = 0.12x^-2.2
This is the second derivative of y with respect to x.
In calculus, a derivative is a measure of how a function changes as its input changes. The second derivative is a measure of how the rate of change of the function itself changes as its input changes. It tells us about the curvature of the function at any given point.
In this case, we have calculated the second derivative of y, which gives us information about the rate of change of the slope of the function. If the second derivative is positive, the function is concave up (curving upward), and if it is negative, the function is concave down (curving downward). If the second derivative is zero, the function has an inflection point (a point where the curvature changes direction).
Overall, the second derivative is a powerful tool in calculus that helps us understand the behavior of functions in more detail.

A restaurant owner rejects his produce shipment if he finds more than 3 crates with any bruised
or spoiled food in it. The probability that a crate has bruised or spoiled food in it is 0.11. What
is the probability that he will reject a shipment of 15 crates?
Answers
The probability of finding 0, 1, 2, or 3 bruised or spoiled crates in a shipment of 15 crates is:
P(X = 0) = (15 choose 0) * (0.11)^0 * (0.89)^15 = 0.27
P(X = 1) = (15 choose 1) * (0.11)^1 * (0.89)^14 = 0.39
P(X = 2) = (15 choose 2) * (0.11)^2 * (0.89)^13 = 0.25
P(X = 3) = (15 choose 3) * (0.11)^3 * (0.89)^12 = 0.09
The probability of finding more than 3 bruised or spoiled crates is:
P(X > 3) = 1 - P(X ≤ 3) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3))
= 1 - (0.27 + 0.39 + 0.25 + 0.09) = 0.01
Therefore, the probability that the restaurant owner will reject a shipment of 15 crates is 0.01 or 1%.

Let f(x) = x^2 (Inx-1). (a) Find the critical numbers of f. (b) Find the open interval(s) on which f is increasing and the open interval(s) on which f is decreasing. (c) Find the local minimum value(s) and local maximum value(s) off. if any. (d) Find the open interval(s) where f is concave upward and the open interval(s) where f is concave downward. (e) Find the inflection point(s) of the graph of f, if any.
Answers
a. The critical number of f is undefine
b. The open interval(s) on f is increasing on (e,∞) and the open interval(s) on which f is decreasing on (0,1) and (1,e).
c. The local minimum value(s) is 0 and there's no local maximum value.
d. Concave downward on (0, e^1/2) and concave upward on (e^1/2, ∞).
e. The inflection point(s) of the graph of f is (e^1/2, e(ln e^1/2 - 1)^2).
(a) To find the critical numbers of f, we need to find where the derivative of f is zero or undefined.
f'(x) = 2x ln x + x - 2x = 2x (ln x - 1) = 0
This gives us x = 1 or x = e. However, f'(x) is undefined at x = 0, so we also need to check this point.
(b) To determine the intervals of increase and decrease, we need to test the sign of f'(x) on each interval.
When x < 1, ln x < 0, so ln x - 1 < -1, and f'(x) < 0.
When 1 < x < e, ln x > 0, so ln x - 1 < 0, and f'(x) < 0.
When x > e, ln x > 1, so ln x - 1 > 0, and f'(x) > 0.
Therefore, f is decreasing on (0,1) and (1,e), and increasing on (e,∞).
(c) To find the local minimum and maximum values, we need to check the critical points and the endpoints of the intervals.
f(1) = 0 is a local minimum.
f(e) = e^2 (ln e - 1) = e^2 (1 - 1) = 0 is also a local minimum.
(d) To find the intervals of concavity, we need to test the sign of f''(x) on each interval.
f''(x) = 2 ln x - 1
When x < e^1/2, ln x < 1/2, so f''(x) < 0, and f is concave downward on (0, e^1/2).
When x > e^1/2, ln x > 1/2, so f''(x) > 0, and f is concave upward on (e^1/2, ∞).
(e) To find the inflection points, we need to find where the concavity changes.
f''(x) = 0 when ln x = 1/2, or x = e^1/2.
Therefore, the inflection point is (e^1/2, f(e^1/2)) = (e^1/2, e(ln e^1/2 - 1)^2).

the probability of choosing H or P in either selection is 0.84
How to find the probability?Two random letters are selected from the word Happy, and we want to find the probability of choosing H or P in either selection.
There are 5 letters, 1 is an H, 2 are P's.
Then the probability of selecting one of these 3 in the first selection is:
p = 3/5 = 0.6
And if we don't chose any of these in the first selection we had the probability:
q = 2/5 = 0.4 (choosing one of the a's)
the probability of choosing one of the p's or the H in the second is again:
q' = 3/5 = 0.6
The joint probability is:
Q = q*q' = 0.4*0.6 = 0.24
Then the total probability is:
p + Q = 0.6 + 0.24 = 0.84
