When strawberry prices increase 20 percent, the quantity demanded of whipped cream falls 10 percent. what is the cross-price elasticity of demand between strawberries and whipped cream?
The cross-price elasticity of demand between strawberries and whipped cream is (C) -0.5.
What is the cross-price elasticity of demand?The cross elasticity of demand, also known as the cross-price elasticity of demand, is a measure in economics that compares the percentage change in the quantity desired for one commodity to the percentage change in the price of another good, everything else being equal. In practice, the amount desired of a thing is affected not only by its own price (price elasticity of demand) but also by the prices of other "related" products.As an example, when strawberry prices rise by 20%, demand for whipped cream falls by 10%. The cross-price elasticity of demand between strawberries and whipped cream is -0.5.Therefore, the cross-price elasticity of demand between strawberries and whipped cream is (C) -0.5.

What is the equation of the line that passes through the point (-6,2) and has a slope of 1?
Answer:
[tex]y = x + 8[/tex]
Step-by-step explanation:
The equation of a line is:
[tex]y = mx + c[/tex]
Where m is the gradient (or as you call it, the slope), and c is the y-intercept. We already know what the slope is, therefore we need to find the y-intercept. You have been given the coordinates (-6, 2), but to find the y-intercept, X must be equal to 0. Since the gradient is 1, we know that for every value we add to X, we must add the same to y. To get from -6 to 0, we must add 6, so we must do the same 2, leaving our y-intercept coordinates as (0, 8), and our y-intercept as 8. Plugging in our values, we are left with the following equation:
[tex]y = x + 8[/tex]
If a hypothesis test is found to have power = 0. 80, which is the probability that the test will result in a type ii error?
The probability that the hypothesis test will result in a type ii error, β is 0.20.
In this question,
A type II error is one of two types of statistical errors that can result from a hypothesis test (the other being a type I error). A type II error will occur if the statistical test is not powerful enough. And it occurs when one rejects the alternative hypothesis (fails to reject the null hypothesis) when the alternative hypothesis is true.
The probability of a type II error is denoted by *beta*, β.
Power of a test = 0.80
The relation between power of a test and type II error is given as,
Power = 1 - type II error
⇒ Type II error, β = 1 - 0.80
⇒ Type II error, β = 0.20
Hence we can conclude that the probability that the hypothesis test will result in a type ii error, β is 0.20.

Mrs. washington has a small fenced-in, rectangular play area behind her house for her dog. there is 80 feet of fencing around the perimeter of the play area, and the width is 14.8 feet. mrs. washington needs to buy new sod to cover the entire area of play space. if sod costs $1.50 per square foot, how much will it cost mrs. washington to buy enough sod for the entire play area?
Answer:
$1118.88
Step-by-step explanation:
Lets start by finding all sides of the perimeter to get an accurate measure of the area.
We know the width is 14.8 feet, that means the opposite side also equals 14.8 feet.
Now the other two sides must sum to 50.4 (80-(14.8*2)) and be equal, so we can divide 50.4 by two to get 25.2 for the other two sides.
Now we can calculate area by multiplying one from each side:
[tex]14.8*50.4=745.92[/tex]
Now to find the price of required sod, multiply the area by cost per square foot
[tex]745.92*1.50=1118.88[/tex]
Therefore it will cost 1118.88 dollars to cover the entire area in sod.
Please help! I've already answered part a, I don't understand what part b is asking.
Step-by-step explanation:
So, there is something known as a removable discontinuity, and it's essentially where you can define f(x) using the most simplified fraction, where you could normally not define f(x).
So we have the following equation:
[tex]f(x) = (\frac{x+5}{x+1}\div\frac{(x+3)(x-2)}{(x-4)(x+1)})-\frac{1}{x-2}[/tex]
As you may know, we cannot divide a number by the value of zero. When the denominator is equal to zero, on the graph this will appear as a vertical asymptote, where x approaches the value that makes the denominator zero, but never actually reaches it.
If you look at each denominator, you can set them equal to zero to find the vertical asymptotes
x+1 = 0
x=-1
There should be a vertical asymptote at x=-1, since it would make two of the denominators equal to -1, but let's divide the two fractions first.
Original Equation
[tex]f(x) = (\frac{x+5}{x+1}\div\frac{(x+3)(x-2)}{(x-4)(x+1)})-\frac{1}{x-2}[/tex]
Keep, change, flip
[tex]f(x) = (\frac{x+5}{x+1}*\frac{(x-4)(x+1)}{(x+3)(x-2)})-\frac{1}{x-2}[/tex]
Multiply the two fractions
[tex]f(x) = (\frac{(x+5)(x-4)(x+1)}{(x+1)(x+3)(x-2)})-\frac{1}{x-2}[/tex]
Notice how the x+1 is in the numerator and fraction? That means we can cancel it out!
[tex]f(x) = (\frac{(x+5)(x-4)}{(x+3)(x-2)})-\frac{1}{x-2}[/tex]
In this simplified version of the fraction, we can technically define f(-1), but in the original version, since it's not defined there is a removable discontinuity at x=-1, meaning there is no vertical asymptote, but the function is still not defined at f(-1), and there will be a hole at that point.
Which elementary row operation will reduce the x–element in row 2 to 0 in this matrix?
The elementary row operation that will reduce the x–element in row 2 to 0 in this matrix is -2R1 + R2
How to determine the elementary row operation?The complete question is added as an attachment

The graph is shown in the attached image.
The final graph of y = -|x + 2| + 3 is a V-shaped curve that opens downwards and is shifted upwards by 3 units.
This curve intersects the x-axis at x = -4 and x = -0 and passes through the point (-2, 1).
The graph is given below.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The graph of y = -x is a straight line that passes through the origin and has a slope of -1.
It extends infinitely in both directions and has a negative slope, which means that as x increases, y decreases.
The graph of y = |x + 2| - 3 is a bit more complex.
The absolute value function |x + 2| means that the value of x + 2 is taken, and then the absolute value of that value is calculated.
The absolute value function always returns a positive value, so the graph of y = |x + 2| is a V-shaped curve that opens upwards and passes through the point (-2, 0).
The minus sign outside the absolute value function means that the entire curve is reflected about the x-axis, so the graph of y = -|x + 2| is also a V-shaped curve, but this time it opens downwards.
Finally, the +3 at the end of the equation means that the entire graph of
y = -|x + 2| is shifted upwards by 3 units.
Thus,
The final graph of y = -|x + 2| + 3 is a V-shaped curve that opens downwards and is shifted upwards by 3 units.
This curve intersects the x-axis at x = -4 and x = -0 and passes through the point (-2, 1).
