Answer:
\(x = -\frac{25}{6} , \frac{19}{6}\)
Step-by-step explanation:
\(|x+\frac{1}{2}| = 3 \frac{2}{3} \\\\|x + \frac{1}{2}| = \frac{11}{3}\\\\ x + \frac{1}{2} = \frac{11}{3}\) \(x + \frac{1}{2} = -\frac{11}{3}\)
\(x = \frac{22}{6} - \frac{3}{6}\) \(x = -\frac{22}{6} - \frac{3}{6}\)
\(x = \frac{19}{6}\) \(x = -\frac{25}{6}\)
\(x = -\frac{25}{6} , \frac{19}{6}\)

Answer:
10.6
Step-by-step explanation:
We can use the Pythagorean Theorem to find the radius, as we are given a right triangle. The hypotenuse is 16. So we have \(r^2 + 12^2 = 16^2\).
Solving for \(r\) (radius), we get \(r = \sqrt{16^2 - 12^2} = 10.6\) (rounded to the nearest tenth place).

A shop sells a washing machine for £236.25, making a profit of 5%. At what wholesale price did the shop buy the washing machine?
Original price = £
Answer:
£225
Step-by-step explanation:
The relationship between the cost price (cp) and the selling price (sp) is ...
cp + 5% × cp = sp
cp(1.05) = sp . . . . . . collect terms
cp = sp/1.05 . . . . . . divide by 1.05
cp = £236.25/1.05 = £225
The original wholesale price was £225.
Convert 20 feet to meters using dimensional analysis and 1 inch = 2.54 cm .
20 feet is equal to 6.096 meters when using the conversion factor of 1 inch = 2.54 cm. We can use dimensional analysis to convert 20 feet to meters.
First, we need to convert feet to inches, since we have a conversion factor of inches to centimeters. We know that 1 foot is equal to 12 inches, so we can write:
20 feet = 20 x 12 inches = 240 inches
Now, we can use the conversion factor of 1 inch = 2.54 cm to convert inches to centimeters. We can write:
240 inches x (2.54 cm / 1 inch) = 609.6 cm
Finally, we can convert centimeters to meters by dividing by 100, since there are 100 centimeters in 1 meter:
609.6 cm ÷ 100 = 6.096 m
Therefore, 20 feet is equal to 6.096 meters when using the conversion factor of 1 inch = 2.54 cm.

a. Compute R2 .
b. Compute Ra 2 .
c. Does the estimated regression equation explain a large amount of the variability in the data?
SelectYesNoItem 3
Based on the equation in the question , the R2 would be 0.934.
To compute R2, we need to use the formula:
R2 = SSR / SST
Given that SSR = 14,141.7 and
SST = 15,128.4,
We can substitute these values into the formula:
R2 = 14,141.7 / 15,128.4
R2 ≈ 0.934
b. To compute Ra2, we need to subtract R2 from 1:
Ra2 = 1 - R2
Substituting the value of R2 we calculated in part a:
Ra2 ≈ 1 - 0.934
Ra2 ≈ 0.066
c. A large R2 value indicates that the estimated regression equation explains a large amount of the variability in the data.
In this case, R2 is approximately 0.934, which means that the estimated regression equation explains about 93.4% of the variability in the data.
So, the answer is "Yes".

Answer: 3060 in³
Step-by-step explanation:
Volume is how much a shape can hold. It's a 3 dimensional measurement so you need to multiply 3 dimensions
V= length x width x height
Sometimes students get confused with which is which side but it really doesn't matter because multiplication is commutative meaning you can switch it and it doesn't matter. Like 5x2 is the same thing as 2x5 both will still be 10
length=15
width=12
height= 17
If Volume = length x width x height

Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229

N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25

Blair & Rosen, Inc. (B&R), is a brokerage firm that specializes in investment portfolios designed to meet the specific risk tolerances of its clients. A client who contacted B&R this past week has a maximum of $85,000 to invest. B&R's investment advisor decides to recommend a portfolio consisting of two investment funds: an Internet fund and a Blue Chip fund. The Internet fund has a projected annual return of 9%, whereas the Blue Chip fund has a projected annual return of 8%. The investment advisor requires that at most $55,000 of the client's funds should be invested in the Internet fund. B&R services include a risk rating for each investment alternative. The Internet fund, which is the more risky of the two investment alternatives, has a risk rating of 6 per thousand dollars invested. The Blue Chip fund has a risk rating of 4 per thousand dollars invested. For example, if $10,000 is invested in each of the two investment funds, B&R's risk rating for the portfolio would be
6(10) + 4(10) = 100.
Finally, B&R developed a questionnaire to measure each client's risk tolerance. Based on the responses, each client is classified as a conservative, moderate, or aggressive investor. Suppose that the questionnaire results classified the current client as a moderate investor. B&R recommends that a client who is a moderate investor limit his or her portfolio to a maximum risk rating of 410.

B. The recommended investment portfolio (in dollars) for this client can be found by reading the values in cells A1 and B1.
C. You can solve for the recommended investment portfolio (in dollars) by reading the values in cells A1 and B1.
D. You can solve for the recommended investment portfolio (in dollars) by reading the values in cells A1 and B1.
(a)
The linear programming model to find the best investment strategy for this client can be formulated as follows:
Maximize: 0.09N + 0.08B
Subject to:
N + B ≤ 85 (maximum investment of $85,000)
N ≤ 55 (maximum investment of $55,000 in the internet fund)
6N + 4B ≤ 410 (maximum risk rating of 410 for a moderate investor)
N, B ≥ 0 (non-negativity constraint)
(b)
To solve the problem using Excel Solver, you can set up the following spreadsheet model:
Cell A1: N (amount invested in the internet fund)
Cell B1: B (amount invested in the Blue Chip fund)
Cell C1: =0.09A1 + 0.08B1 (annual return for the portfolio)
Constraints:
Cell A2: ≤ 85
Cell B2: ≤ 85
Cell C2: ≤ 55
Cell D2: ≤ 410
The objective is to maximize the value in cell C1 by changing the values in cells A1 and B1, subject to the constraints.
Using Excel Solver, set the objective to maximize the value in cell C1 by changing the values in cells A1 and B1, subject to the constraints in cells A2, B2, C2, and D2.
The recommended investment portfolio (in dollars) for this client can be found by reading the values in cells A1 and B1.
(b)
For the aggressive investor with a maximum portfolio risk rating of 450, the linear programming model remains the same, except for the constraint on the maximum risk rating.
The new constraint would be: 6N + 4B ≤ 450
Using the same spreadsheet model as before, with the updated constraint, you can solve for the recommended investment portfolio (in dollars) by reading the values in cells A1 and B1.
(d)
For the conservative investor with a maximum portfolio risk rating of 320, the linear programming model remains the same, except for the constraint on the maximum risk rating.
The new constraint would be: 6N + 4B ≤ 320
Using the same spreadsheet model as before, with the updated constraint, you can solve for the recommended investment portfolio (in dollars) by reading the values in cells A1 and B1.

Answer:
1. 5
2. 3 adult tickets; 2 child tickets
3. See below
Step-by-step explanation:
1.
2 adult tickets cost 2 × $12 = $24
Subtract $24 from $64:
$64 - $24 = $40
Divide $40 by $8:
$40 ÷ $8 = 5
Answer: 5 child tickets
2.
x = number of adult tickets
y = number of child tickets
The total number of tickets is 5, so the first equation is:
x + y = 5
The cost of x adult tickets is 12x. The cost of y child tickets is 8y. The total cost is 12x + 8y. We are told the total cost is $52. The second equation is:
12x + 8y = 52
The system of equation is:
x + y = 5
12x + 8y = 52
Let's solve it by substitution.
Solve the first equation for x.
x = 5 - y
Now we substitute x in the second equation by 5 - y.
12(5 - y) + 8y = 52
Distribute:
60 - 12y + 8y = 52
Combine like terms on the left side:
-4y + 60 = 52
Subtract 60 from both sides:
-4y = -8
Divide both sides by 4.
y = 2
Substitute y = 2 in the first original equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
Answer: 3 adult tickets; 2 child tickets
3.
The customer's claim is incorrect. His sum is $71. 71 is an odd number. Since all ticket prices are even numbers, it is impossible to add only even numbers and get an odd sum. A sum of several amounts of 12 and several amounts of 8 can never equal 71.
We can also show his claim is false using a system of equations.
x + y = 7
12x + 8y = 71
Use substitution.
x = 7 - y
12(7 - y) + 8y = 71
84 - 12y + 8y = 71
84 - 4y = 71
-4y = -13
y = 3.25
This means 3.25 child tickets. The problem states that tickets can be purchased only in whole numbers, so 3.25 tickets cannot be purchased, so the customer's claim is false.

Chicago's Hard Rock Hotel distributes a mean of 1,200 bath towels per day to guests at the pool and in their rooms. This demand is normally distributed with a standard deviation of 105 towels per day, based on occupancy. The laundry firm that has the linen contract requires a 4-day lead time. The hotel expects a 98% service level to satisfy high guest expectations. Refer to the for z-values. a) What is the reorder point? towels (round your response to the nearest whole number).
The reorder point for bath towels at Chicago's Hard Rock Hotel is approximately 1,494 towels.
To calculate the reorder point, we need to consider the mean demand, lead time, and the desired service level. The mean demand for bath towels is given as 1,200 per day, and the standard deviation is 105 towels per day.
Since the hotel wants to maintain a 98% service level, we need to find the corresponding z-value from the standard normal distribution table. A 98% service level corresponds to a z-value of approximately 2.05.
To calculate the reorder point, we need to consider the lead time. In this case, the lead time is 4 days.
The formula to calculate the reorder point is:
Reorder point = Mean demand during lead time + (Z-value * Standard deviation of demand during lead time)
Calculating the mean demand during lead time:
Mean demand during lead time = Mean demand per day * Lead time
Mean demand during lead time = 1,200 towels/day * 4 days = 4,800 towel
Calculating the standard deviation of demand during lead time:
Standard deviation of demand during lead time = Standard deviation per day * √(Lead time)
Standard deviation of demand during lead time = 105 towels/day * √(4) = 210 towels
Substituting the values into the reorder point formula:
Reorder point = 4,800 towels + (2.05 * 210 towels) = 4,800 towels + 430.5 towels ≈ 1,494 towels
Therefore, the reorder point for bath towels at Chicago's Hard Rock Hotel is approximately 1,494 towels.

find the taylor series of f centered at 0 (maclaurin series of f) . f(x) = x6sin(10x5)
Maclaurin series of `f(x)` is given by:f(x) = `f(0)` + `f'(0)x` + `(f''(0)/2!) x²` + `(f'''(0)/3!) x³` + `(f⁴(0)/4!) x⁴` + `(f⁵(0)/5!) x⁵` + `(f⁶(0)/6!) x⁶` = `0 + 0x + 0x² + 0x³ + 0x⁴ + 0x⁵ + (7200/6!)x⁶` = `10x⁶`
Answer: `10x⁶`.
The given function is `f(x) = x⁶ sin(10x⁵)`. We need to find the Taylor series of `f` centered at `0` (Maclaurin series of `f`).
Formula used: The Maclaurin series for `f(x)` is given by `f(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ...... + (f^n(0)/n!)x^n`.
Here, `f(0) = 0` because `sin(0) = 0`.
Differentiating `f(x)` and its derivatives at `x = 0`:`f(x) = x⁶ sin(10x⁵)`
First derivative: `f'(x) = 6x⁵ sin(10x⁵) + 50x¹⁰ cos(10x⁵)`
Differentiate `f'(x)`
Second derivative: `f''(x) = 30x⁴ sin(10x⁵) + 200x⁹ cos(10x⁵) - 250x¹⁰ sin(10x⁵)`
Differentiate `f''(x)`
Third derivative: `f'''(x) = 120x³ sin(10x⁵) + 1800x⁸ cos(10x⁵) - 2500x⁹ sin(10x⁵) - 5000x²⁰ cos(10x⁵)`
Differentiate `f'''(x)`
Fourth derivative: `f⁴(x) = 360x² sin(10x⁵) + 7200x⁷ cos(10x⁵) - 22500x⁸ sin(10x⁵) - 100000x¹⁹ cos(10x⁵) + 100000x²⁰ sin(10x⁵)`
Differentiate `f⁴(x)`
Fifth derivative: `f⁵(x) = 720x sin(10x⁵) + 36000x⁶ cos(10x⁵) - 112500x⁷ sin(10x⁵) - 1900000x¹⁸ cos(10x⁵) + 2000000x¹⁹ sin(10x⁵)`
Differentiate `f⁵(x)`
Sixth derivative: `f⁶(x) = 7200 cos(10x⁵) - 562500x⁶ cos(10x⁵) + 13300000x¹⁷ sin(10x⁵)`
Evaluate at `x = 0`:
The derivatives of `f(x)` evaluated at `x = 0` are:f(0) = 0f'(0) = 0f''(0) = 0f'''(0) = 0f⁴(0) = 0f⁵(0) = 0f⁶(0) = 7200
Maclaurin series of `f(x)` is given by:f(x) = `f(0)` + `f'(0)x` + `(f''(0)/2!) x²` + `(f'''(0)/3!) x³` + `(f⁴(0)/4!) x⁴` + `(f⁵(0)/5!) x⁵` + `(f⁶(0)/6!) x⁶` = `0 + 0x + 0x² + 0x³ + 0x⁴ + 0x⁵ + (7200/6!)x⁶` = `10x⁶`
Answer: `10x⁶`.

calculate the coefficient of variation for a sample of cereal boxes with a mean weight of 340 grams and a standard deviation of 5.2 grams.? 0.15% A
1.53% B
15.29% C
0.65% D
The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.
In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.
CV = (Standard Deviation / Mean) * 100
CV = (5.2 / 340) * 100
CV ≈ 1.53%
Therefore, the correct answer is option B: 1.53%.
