Mary basic salary was 3. 700 plus 25 perecnt overtime payment last month how much did she receive altogether last month
Answers
Mary's total payment last month can be calculated by adding her basic salary to her overtime payment. Mary received a total payment of $4,625 last month.
Her basic salary was $3,700.
To find out the amount of her overtime payment, we need to calculate 25% of her basic salary.
25% of $3,700 can be found by multiplying $3,700 by 0.25 (since 25% is equivalent to 0.25).
So, 25% of $3,700 is $925 ($3,700 x 0.25 = $925).
Now, we can find Mary's total payment by adding her basic salary and her overtime payment.
$3,700 + $925 = $4,625

what are the two dimensions on the retail positioning matrix?
Answers
The Retail Positioning Matrix is a tool used in retail marketing that helps to visualize and evaluate potential positioning strategies. It is composed of two main dimensions: price and quality.
While quality relates to the perceived value of a product or service in terms of its features, advantages, and performance, price is the amount of money consumers are prepared to pay for a good or service.
High price/high quality, high price/poor quality, low price/high quality, and low price/low quality are the four quadrants that the matrix divides price and quality into.
Retailers can choose which positioning approach will work best in a particular market by looking at each of these four quadrants, which each feature a different positioning strategy.

The perimeter of a triangle is 510 feet and the sides are in the ratio of 11:16:24.Find the area of the triangle
Answers
Answer:
Given, hope it helps!
Step-by-step explanation:
Perimeter= 510 feet
Perimeter is the sum of sides so..
16x + 11x + 24x = 510
51x = 510
x = 510/51 = 10
(10*24), (10*11), (10*16)
So the sides are 160ft 110ft and 240ft
Area is equal to √s(s-a)(s-b)(s-c)
where s is the semiperimeter= 510/2 = 255
and a, b and c are the sides
area =
√ 255(255-240)(255-110)(255-160)
= √ 255*15*145*95
= √ 52,689,375
= 7258.74 feet ^2
Answer:
A=7258.74472
Step-by-step explanation:
Multiply the side ratios by x
Add them together to get the perimeter
11x+16x+24x = 510
51 x =510
x = 10
The sides are 110, 160 240
We have to use herons formula
A = sqrt( p (p-a) (p-b)(p-c)) where p is the perimeter/2 and a,b,c are the side lengths
A = sqrt( 510/2 (510/2-110) (510/2-160)(510/2-240))
A = sqrt( 255 (145) (95)(15))
A = sqrt(52689375)
A=7258.74472
The super sub at Sandwich Station consists of 4 different toppings and 3 different condiments. How many different super subs can be made if there are 8 toppings, 6 condiments, and 6 types of homemade bread to choose from?

Therefore, there are 53,248 different super subs that can be made if there are 8 toppings, 6 condiments, and 6 types of homemade bread to choose from at Sandwich Station.
The super sub at Sandwich Station consists of 4 different toppings and 3 different condiments. The question is asking how many different super subs can be made if there are 8 toppings, 6 condiments, and 6 types of homemade bread to choose from.
To solve this problem, we can use the multiplication principle of counting. The multiplication principle states that if there are m ways to do one thing and n ways to do another thing, then there are m x n ways to do both things.
Let's use the multiplication principle to solve this problem. There are four different toppings, and we can choose any of the eight toppings for each of the four spots.
Using the multiplication principle, there are
8 x 8 x 8 x 8 = 4096
ways to choose the toppings. Similarly, there are
6 x 6 x 6 = 216
ways to choose the condiments. Lastly, there are 6 different types of homemade bread to choose from. Using the multiplication principle again, there are
4096 x 216 x 6 = 53,248,
which means there are 53,248 ways to make the super subs.

1) There are more red jelly beans expected in B than the black jelly beans expected in A.
2) There are more black jelly beans expected in A than the red jelly beans expected in B.
3) The number of red jelly beans expected in B and the number of black jelly beans expected in A are the same.
4) There is not enough information.
(b) Either mathematically or in plain English, justify your answer.
Answers
Option 3) The number of red jelly beans expected in B and the number of black jelly beans expected in A are the same.
(b) Justification: Initially, Jar-A has 380 red jelly beans and Jar-B has 380 black jelly beans. When you scoop 20 red jelly beans from A and put them into B, Jar-B has 380 black jelly beans and 20 red jelly beans. After shaking, you scoop 20 jelly beans from B and put them into A. Since you took out 20 jelly beans from B, it will still have 380 jelly beans. The probability of picking a red jelly bean from B is now 20/380, so you can expect to return approximately
(20/380) × 20 = 20/19 ≈ 1 red jelly bean to A, leaving 19 red jelly beans in B.
Similarly, you can expect to have 20 - 1 = 19 black jelly beans in A,
as you scooped out 20 jelly beans from B. Therefore, the number of red jelly beans expected in B and the number of black jelly beans expected in A are the same.

Write the following equation in standard form. Identify the related conic. x' + y2 - 8x - 6y - 39 = 0
Answers
The standard form of the equation is (x' - 8x) + (y - 3)^2 = 48
To write the equation in standard form and identify the related conic, let's rearrange the given equation:
x' + y^2 - 8x - 6y - 39 = 0
Rearranging the terms, we have:
x' - 8x + y^2 - 6y - 39 = 0
Now, let's complete the square for both the x and y terms:
(x' - 8x) + (y^2 - 6y) = 39
To complete the square for the x terms, we need to add half the coefficient of x (-8) squared, which is (-8/2)^2 = 16, inside the parentheses. Similarly, for the y terms, we need to add half the coefficient of y (-6) squared, which is (-6/2)^2 = 9, inside the parentheses:
(x' - 8x + 16) + (y^2 - 6y + 9) = 39 + 16 + 9
(x' - 8x + 16) + (y^2 - 6y + 9) = 64
Now, let's simplify further:
(x' - 8x + 16) + (y^2 - 6y + 9) = 8^2
(x' - 8x + 16) + (y - 3)^2 = 8^2
(x' - 8x + 16) + (y - 3)^2 = 64
Now, we can rewrite this equation in standard form by rearranging the terms:
(x' - 8x) + (y - 3)^2 = 64 - 16
(x' - 8x) + (y - 3)^2 = 48
The equation is now in standard form. From this form, we can identify the related conic. Since we have a squared term for y and a constant term for x (x' is just another variable name for x), this equation represents a parabola opening horizontally.

Answers
To propagate the error for the given functions, we can use the rules of error propagation.
Let's consider each function separately:
a. For the function y = 5asin(x), where a is a constant:
To propagate the error, we need to consider the derivative of the function with respect to x. In this case, the derivative is cos(x).
Therefore, the propagated error for y is σy = |5a * cos(x) * σx|.
b. For the function y = ax + 2z, where a is a constant:
The propagated error for y is σy = |a * σx + 2 * σz|.
c. For the function y = \(bxz^2\), where b is a constant:
The propagated error for y is σy = \(|(xz^2)\)* σb + (2bxz) * σx + (2bxz) * σz|.
d. For the function y = bln(x), where b is a constant:
The propagated error for y is σy = |(b/x) * σx|
e. For the function f(x, y) = \(yx^2 + y^2:\)
To propagate the error for this function, we need to consider the partial derivatives of f with respect to x and y. The propagated error for f is given by:
σf =\(sqrt((∂f/∂x)^2 * σx^2 + (∂f/∂y)^2 * σy^2),\)
where ∂f/∂x is the partial derivative of f with respect to x, and ∂f/∂y is the partial derivative of f with respect to y.
f. For the function f(x, y) = x + y/(x - y):
The propagated error for f is σf = \(sqrt((∂f/∂x)^2 * σx^2 + (∂f/∂y)^2 * σy^2),\)
where ∂f/∂x is the partial derivative of f with respect to x, and ∂f/∂y is the partial derivative of f with respect to y.
Please note that these formulas assume that the errors in the variables (σx, σy, σz, etc.) are independent and have Gaussian distributions.

Step-by-step explanation:
Factoring is the process of breaking a polynomial into its factors.
Standard Form
It is easiest to factor when in standard form. Standard form is when the terms are listed from highest power to lowest.
Standard form is \(x^2-6x+8\)Factoring
To find if two expressions are equal we can either factor the quadratic or multiply out the binomials. I find factoring to be faster and easier, so I will show that.
There are multiple techniques to factor; I will be explaining one of them. One way to factor quadratics is to find 2 numbers that multiply to c (the constant) and sum to b (the second term). In this case, the numbers -4 and -2 fit these requirements.
-4 * -2 = 8-4 + -2 = -6This means that \(x^2-6x+8\) factored is \((x-4)(x-2)\). Thus, they are equivalent.

The point estimate for least-squares regression line x=1 is approximately 3.85, and the point estimate for x=7 is approximately 24.02.
What is coefficient of linear regression?In a linear regression, the coefficient of determination (R-squared) is a statistical indicator that shows how much of the variance in the dependent variable is explained by the independent variable (s). Higher values suggest a better fit of the regression line to the data, and it has a value between 0 and 1. R-squared is derived by dividing the regression's sum of squares (SSR) by the sum of all squares (SST).
The least-squares regression line is given by the formula:
b1 = Σ[(xi - x)(yi - y)] / Σ[(xi - x)²]
The means of x and y:
x = (−2 + 2 + 5 + 7 + 10) / 5 = 4.4
y = (2 + 9 + 13 + 19 + 24) / 5 = 13.4
Substituting the value we have:
Σ[(xi - x)(yi - y)] = (-2-4.4)(2-13.4) + (2-4.4)(9-13.4) + (5-4.4)(13-13.4) + (7-4.4)(19-13.4) + (10-4.4)(24-13.4) = 400.8
Σ[(xi - x)²] = (-2-4.4)²+ (2-4.4)² + (5-4.4)² + (7-4.4)² + (10-4.4)² = 86.8
Thus, the value of:
b1 = Σ[(xi - x)(yi - y)] / Σ[(xi - x)²] = 400.8 / 86.8 ≈ 4.617
Now, for y-intercept we have:
b0 = y - b1x = 13.4 - 4.617(4.4) ≈ -0.767
y = -0.767 + 4.617x
Now, the point estimate is:
For x=1, y = -0.767 + 4.617(1) ≈ 3.85
For x=7, y = -0.767 + 4.617(7) ≈ 24.02
Therefore, the point estimate for x=1 is approximately 3.85, and the point estimate for x=7 is approximately 24.02.

Answers
The 90% confidence interval for the difference in the population means is -2.51 to 0.31
Calculating the 90% confidence interval for the population mean differenceFrom the question, we have the following parameters that can be used in our computation:
xˉ₁ = −17.1
s₁² = 8.4
n₁ = 22
xˉ₂ = −16.0
s₂² = 8.7
n₂ = 24
Calculate the pooled variance using
P = (df₁ * s₁² + df₂ * s₂²)/df
Where
df₁ = 22 - 1 = 21
df₂ = 24 - 1 = 23
df = 22 + 24 - 2 = 44
So, we have
P = (21 * 8.4 + 23 * 8.7)/44
P = 8.56
Also, we have the standard error to be
SE = √(P/n₁ + P/n₂)
So, we have
SE = √(8.56/22 + 8.56/24)
SE = 0.86
The z score at 90% CI is 1.645, and the CI is calculated as
CI = (x₁ - x₂) ± z * SE
So, we have
CI = (-17.1 + 16.0) ± 1.645 * 0.86
This gives
CI = -1.1 ± 1.41
Expand and evaluate
CI = (-2.51, 0.31)

"Derive the demand function
Endowment (1,0)
U(x,y) = -e⁻ˣ — e⁻ʸ
Answers
To derive the demand function from the given utility function and endowment, we need to determine the optimal allocation of goods that maximizes utility. The utility function is U(x, y) = -e^(-x) - e^(-y), and the initial endowment is (1, 0).
To derive the demand function, we need to find the optimal allocation of goods x and y that maximizes the given utility function while satisfying the endowment constraint. We can start by setting up the consumer's problem as a utility maximization subject to the budget constraint. In this case, since there is no price information provided, we assume the goods are not priced and the consumer can freely allocate them.
The consumer's problem can be stated as follows:
Maximize U(x, y) = -e^(-x) - e^(-y) subject to x + y = 1.
To solve this problem, we can use the Lagrangian method. We construct the Lagrangian function L(x, y, λ) = -e^(-x) - e^(-y) + λ(1 - x - y), where λ is the Lagrange multiplier.
Taking partial derivatives of L with respect to x, y, and λ, and setting them equal to zero, we can find the values of x, y, and λ that satisfy the optimality conditions. Solving the equations, we find that x = 1/2, y = 1/2, and λ = 1. These values represent the optimal allocation of goods that maximizes utility given the endowment.
Therefore, the demand function derived from the utility function and endowment is x = 1/2 and y = 1/2. This indicates that the consumer will allocate half of the endowment to each good, resulting in an equal distribution.

You have to move 2 over to the 17 to get the x by itself so since it’s a positive 2, you would subtract 2 which would give you -3x>15. THEN you would divide the 15 by negative 3 which gives you -5 BUT since you are dividing by a negative you would flip the sign.
Hope this helped!!
