The demand function for the shirts of a concert-promoting company which has been selling an average of 175 T-shirts at performances for $23 each is y=175-6.08x.

The demand function is the function

[tex]Q=a-bP[/tex]

Here, Q is linear demand curve, a factor which influence the demand, b is slope and P is price.

A concert-promoting company has been selling an average of 175 T-shirts at performances for $23 each. Thus, the total selling price is,

[tex]P=175\times23\\P=4025[/tex]

The company estimates that for each dollar that the price is lowered, an additional 25 shirts will be sold.  Thus, the total number of

[tex]23=175-25b\\23-175=-25b\\b=\dfrac{152}{25}\\b=6.08[/tex]

Put the values in, the function for X number of shirt and y price,

[tex]y=175-6.08x[/tex]

Hence, the demand function for the shirts of a concert-promoting company which has been selling an average of 175 T-shirts at performances for $23 each is y=175-6.08x.

The probability of picking a chocolate-covered cherry is 0.

The probability that an a fell on the floor is 0.08

The probability that an a or a o would be picked is 0.36

The probability a girl would be picked is 1.

Probability is used to calculate the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability of picking a chocolate-covered cherry is zero because there is no chocolate-covered cherry in the bag.  

The probability that an a fell on the floor = number of a in the letter / total number of letters

= 1/13 = 0.08

The probability that an s or a o would be picked is = (number of s in the letter / total number of letters) +  (number of 0 in the letter / total number of letters)

= 4/11 + 0 = 4/11 = 0.36

The probability a girl would be picked is one since its an all-girls school.

Answer:

The probability that a student taking only math will get picked is approximately 29%

Step-by-step explanation: This is because out of the total number of students taking math (95), 52 of such students are also taking science. In order to get the number of students only taking math you have to do 95-52=43 and to put that against the amount of total students the ratio would be 43:147 or 42/147 and if you plug 42/147 into a calculator you will recieve a long decimal that you can then round to 29%.

Answer:

B.  3.53*4.37^x

Step-by-step explanation:

See attached graph.

The exponential regression equations that best fits the data is y = 3.53(4.37)ˣ

The equation of an exponential regression model takes the following form: y = abˣ where: y: The response variable x: The predictor variable a, b: The regression coefficients that describe the relationship between x and y.

Given is a table, we need to determine the exponential regression equation, for the same,

So,

The general exponential regression equations is, y = abˣ

where, a is initial value and b is growth factor.

Using graph calculator, we get,

a = 3.53

b = 4.37

Put the value of a and b in general equation, to find the exponential regression equation.

y = 3.53(4.37)ˣ

Hence the option B is correct.

Answer:

derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the result is the slope of the original function y = f (x).

There are many different ways to indicate the operation of differentiation, also known as finding or taking the derivative. The choice of notation depends on the type of function being evaluated and upon personal preference.

Suppose you have a general function: y = f(x). All of the following notations can be read as "the derivative of y with respect to x" or less formally, "the derivative of the function."

f'(x) f' y' df/dx dy/dx d/dx [f(x)].

[HINT: don't read the last three terms as fractions, read them as an operation.

For example, read: " dx/dy = 3x"

As: "the function that gives the slope is equal to 3x"

Let's try some examples. Suppose we have the function : y = 4x3 + x2 + 3.

After applying the rules of differentiation, we end up with the following result:

dy/dx = 12x2 + 2x.

How do we interpret this? First, decide what part of the original function (y = 4x3 + x2 + 3) you are interested in. For example, suppose you would like to know the slope of y when the variable x takes on a value of 2. Substitute x = 2 into the function of the slope and solve:

dy/dx = 12 ( 2 )2 + 2 ( 2 ) = 48 + 4 = 52.

Therefore, we have found that when x = 2, the function y has a slope of + 52.

Now for the practical part. How do we actually determine the function of the slope? Almost all functions you will see in economics can be differentiated using a fairly short list of rules or formulas, which will be presented

Answer: Yes this is a right triangle

We can determine this by using the converse of the pythagorean theorem.

a = 5, b = 12, c = 13

[tex]a^2 + b^2 = c^2\\\\5^2 + 12^2 = 13^2\\\\25 + 144 = 169\\\\169 = 169 \ \ \checkmark\\\\[/tex]

Since those a,b,c values work in the pythagorean theorem, this proves we have a right triangle.

Let be a vector in rectangular form, that is, a vector of the form (x, y). A vector in polar (trigonometric) form is defined by the following expression: (r, θ)

And the magnitude (r) and direction of the vector (θ), in degrees, are, respectively:
