For the following demand function, find a. E, and b. the values of q (if any) at which total revenue is maximized.
q=40,600−9p2
a. Determine the elasticity of demand, E.
E=______ (Type an expression using p as the variable.)
b. Determine the value of q that maximizes the revenue. Select the correct choice below, and if necessary, fill in the answer box within your choice.
A.Total revenue is maximized at about, q=___
B. No value of q
Answers
a. The elasticity of demand is E = -1.607.
b. Total revenue is maximized at q ≈ 1354.00.
The demand function is: q = 40,600 - 9p^2
a. To find the elasticity of demand, we need to differentiate the demand function with respect to p and then multiply by p/q:
dq/dp = -18p
(p/q) * (dq/dp) = (-18p/q)
Then, we can substitute p = 2000 and q = 22,400 (the values given in a previous question) into this expression:
E = (-18(2000)/22400) = -1.607
b. Total revenue is maximized where the demand is unit elastic (E = -1). We can set the expression for E equal to -1 and solve for p to find the corresponding value of q:
-1 = (-18p/q)
q = 18p
Substituting the demand function into this expression and simplifying, we get:
q = 40,600 - 9p² = 18p
Rearranging and solving for p, we get:
9p² + 18p - 40,600 = 0
Using the quadratic formula, we get:
p = (-18 ± √(18² - 4(9)(-40,600)))/(2(9)) ≈ 75.22 or -227.22
Since the price must be positive, the only valid solution is p ≈ 75.22. Substituting this back into the demand function, we get:
q ≈ 18(75.22) ≈ 1354.00

In what ratio does the line of the equation 4x + 5y = 21 divide the line segment joining the points (-2, 3) and (4, 5) ?
Answers
Answer: 1.465 : 1
Step-by-step explanation:
Slope of the line segment:
m = (5 - 3)/(4 - (-2)) = 2/6 = 1/3
The equation of the line which the line segment lies on is found by:
(y - 3)/(x - (-2)) = 1/3
(y - 3)/(x + 2) = 1/3
(y - 3)/(x + 2) * (x + 2) = 1/3 * (x + 2)
y - 3 = (x + 2)/3 = 1/3 x + 2/3
y = 1/3 x + 11/3
The equation of the line given:
4x + 5y = 21
5y = -4x + 21
y = -4/5 * x + 21/5
Set them equal to each other and solve for x to find their intersection:
1/3 x + 11/3 = -4/5 * x + 21/5
15(1/3 x + 11/3) = 15(-4/5 * x + 21/5)
5 x + 55 = -12 x + 63
17x = 8
x = 8/17
y = 1/3 (8/17) + 11/3 = 8/51 + 181/51 = 189/51
Point (8/17, 189/51)
Distance from right end of segment to intersection:
s = SQRT((4 - 8/17)^2 + (5 - 189/51)^2) = SQRT((60/17)^2 + (66/51)^2) = 3.759
length of segment = SQRT((5–3)^2 + (4 - (-2))^2) = SQRT(4 + 36) = SQRT(40) = 6.324
Distance from the left end to interseciton:
6.324 - 3.759 = 2.555
Ratio of right end to left end:
3.759/2.565 = 1.465
a production process that is in control has a mean of 80 and a standard deviation of 10. what are the upper and the lower control limits for sample sizes of 25?
Answers
A production process that is in control has a mean of 80 and a standard deviation of 10. The upper and the lower control limits for sample sizes of 25 is 124 and 36 respectively.
The production process that is in control has a mean of 80 and a standard deviation of 10.
To find the upper and lower control limits for a sample size of 25, we need to calculate the following formulas:
Upper Control Limit (UCL) = mean + 3*standard deviation
Lower Control Limit (LCL) = mean - 3*standard deviation
Therefore, for this process with a mean of 80 and standard deviation of 10, the UCL is 130 and the LCL is 30.
For sample sizes of 200, the formulas will be slightly different as the control limits are adjusted for larger samples:
UCL = mean + 2.66 x standard deviation
LCL = mean - 2.66 x standard deviation
Therefore, the UCL is 124 and the LCL is 36.

We may conclude after answering the provided question that angles NM = 10 + 6 = 16 (as seen in the figure) m JML = 60 - x m KML = 120 m
what are angles?An angle is a form in Euclidean geometry that is made up of two rays that meet at a point in the centre known as the angle's vertex. Two rays may combine to form an angle in the plane where they are situated. When two planes intersect, an angle is generated. They are referred to as dihedral angles. An angle in plane geometry is a potential configuration of two radiations or lines that represent a termination. The word "angle" comes from the Latin word "angulus," which meaning "horn." The vertex is the place where the two rays, also known as the angle's sides, meet.
Let x be the angle JML measurement. Next, using the angle connections we discovered earlier:
m LKN = x m KML = m LMN = 180 minus x (since they form a linear pair with angle JML)
180 - x - (180 - m LKN) m JML
JML m = LKN m - x
JML = 60 - x KML = m LMN = 180 - 60 = 120 F
JMN = JML (alternative interior angles) KMN = KML (alternate interior angles) m JMN + KMN + m N = 180 (angles in a triangle)
m JMN = 60 x m KMN = 120 60 x + 120 + m N = 180 m N = x
As a result, we have:
LK + KL = NM (segment addition postulate)
NM = 10 + 6 = 16 (as seen in the figure) m JML = 60 - x m KML = 120 m

The value of 2 (x²+2/x²) is D) 1/4.the calculation is given below.
What is value?Value in math is a measure of the amount of a quantity, such as size, cost, or weight. It is used to compare different quantities or compare different elements in a set. Value can be measured in a variety of ways, such as absolute value, relative value, or fractional value. Ultimately, value helps to explain how different elements interact and relate to one another.
Solution:
The given equation is:
sin θ = 2x
cos θ = 2
0°< θ < 90°
Now we can solve for x using the first equation to get
x = sinθ/2
Now we can substitute this value of x in the second equation and solve for θ
2 = cosθ
θ = cos-1 (2)
θ = 60°
Thus, x = sin60°/2
x = √3/2
Now we can substitute this value of x in the given equation and solve for the value of 2 (x²+2/x²)
2 (x²+2/x²) = 2 ((√3/2)²+ 2/ (√3/2)²)
2 (x²+2/x²) = 2 (3/2 + 2/3)
2 (x²+2/x²) = 2 (5/3)
2 (x²+2/x²) = 10/3
Therefore, the value of 2 (x²+2/x²) is D) 1/4.

Answers
The correct statement is:
d. The binomial distribution is a discrete probability distribution and the normal distribution is a continuous probability distribution.
What is binomial distribution?
In probability theory and statistics, the binomial distribution is the discrete probability distribution that gives only two possible results in an experiment, either Success or Failure. For example, if we toss a coin, there could be only two possible outcomes: heads or tails, and if any test is taken, then there could be only two results: pass or fail. This distribution is also called a binomial probability distribution.
The binomial distribution is a discrete probability distribution that models the number of successes in a fixed number of independent trials, where each trial can result in only two outcomes (success or failure), and the probability of success is constant. Examples of situations that can be modeled by a binomial distribution include flipping a coin a fixed number of times or counting the number of defective items in a batch of products.
The normal distribution, on the other hand, is a continuous probability distribution that is often used to model naturally occurring phenomena, such as heights, weights, and test scores. The normal distribution is characterized by a bell-shaped curve, and it is used because many phenomena in nature follow a normal distribution pattern.
So, the binomial and normal distributions are both widely used in probability and statistics, but they are fundamentally different types of distributions.

Determine the average rate of a function
Answers
The average rate of change of the quadratic function f(x) on the interval [0, 15] is equal to 23.
How to determine the average rate of change?In Mathematics, the average rate of change of a function f(x) on a closed interval [a, b] can be determined by using this mathematical equation (formula):
Average rate of change = [f(b) - f(a)]/(b - a)
Next, we would determine the average rate of change of the function f(x) over the interval [0, 15]:
a = 0; f(a) = -x² + 8x + 20
f(0) = -0² + 8(0) + 20
f(0) = 20
b = 9; f(b) = 365
f(15) = -15² + 8(15) + 20
f(15) = 365
By substituting the parameters into the average rate of change formula, we have the following;
Average rate of change = (365 - 20)/(15 - 0)
Average rate of change = 345/15
Average rate of change = 23.

Answers
Answer:

Step-by-step explanation:
Step-by-step explanation:
To multiply decimals, we can simply multiply the numbers as if they were whole numbers and then count the total number of decimal places in the factors. In this case, we have:
25.5 x 10 x 10 = 255 x 10
Now, we multiply 255 by 10 as if they were whole numbers:
255 x 10 = 2550
Finally, we count the total number of decimal places in the factors, which is two (one in 25.5 and one in 10). Therefore, the answer should have two decimal places, so we can add a decimal point to the result and place two zeros after it:
25.5 x 10 x 10 = 2550.00
Therefore, 25.5 x 10 x 10 = 2550.00.

In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two points are not equal, the not equal sign is commonly used (). Different inequalities, no matter how small or large, are utilized to calculate contrast values. Many simple inequalities can be solved by modifying its two sides until only the variables remain. But a few factors contribute to inequality: Negative values are divided or added on both sides. Trade off the left and right.
Mrs. A always grills more onions than peppers, so the number of onions grilled (38) must be greater than the number of peppers grilled (38). (x). As a result, the inequality can be used to represent this relationship:

2,000x + 6,000 = 3,500x - 39,000
Subtracting 2,000x from both sides, we get:
6,000 = 1,500x - 39,000
Adding 39,000 to both sides, we get:
45,000 = 1,500x
Dividing both sides by 1,500, we get:
x = 30
Therefore, the solution to the equation 2,000x + 6,000 = 3,500x - 39,000 is x = 30.
To find the actual number of hours that Carlos and Jacob need to work to earn the same amount of money, we can plug in x = 35 into both of their income expressions and set them equal to each other:
2,000(35) + 6,000 = 3,500(35) - 39,000
Simplifying, we get:
76,000 = 76,000
This means they will earn the same amount of money if they each work 35 hours per week.
Therefore, the manager predicts that Carlos and Jacob need to work 35 hours each to earn the same amount of money.

A wire reaches from the top of a 26-meter telephone pole to a point on the ground 8 meters from the base of the pole. What is the length of the wire to the nearest tenth of a meter?
Answers
Answer: We can use the Pythagorean theorem to solve for the length of the wire. Let's call the length of the wire "x". Then:
x^2 = 26^2 + 8^2
x^2 = 676 + 64
x^2 = 740
x = sqrt(740)
x ≈ 27.2
Therefore, the length of the wire to the nearest tenth of a meter is 27.2 meters.
Step-by-step explanation:
Last year the city of Goose Pimple, Vermont, paid an average of $3,261 per employee in health care costs (including insurance and additional claims). This year the city management decided that they will contract with Grimms Health Maintenance Organization. At the end of the year they would like to know if they have saved any money. They take a sample of 50 and find a sample mean of $3,015 with a standard deviation of $1,745. Present a hypothesis, a null hypothesis, and evaluate the hypothesis. Explain in plain English what you have found
Answers
The solution to the offered question depends on the hypothesis the response is the determined t-worth of - 2.58 is not exactly the basic t-worth of - 2.009, we can't dismiss the invalid hypothesis.
To evaluate the hypothesis, we will play out a one-example t-test. The test measurement is determined as:
t = (test mean - populace mean)/(test standard deviation/sqrt(sample size))
Expecting an importance level of 0.05, we will dismiss the invalid hypothesis if the determined t-esteem is more noteworthy than the basic t-esteem.
Populace mean = $3,261 (given)
Test mean = $3,015
Test standard deviation = $1,745
Test size = 50
t = (3015 - 3261)/(1745/sqrt(50)) = - 2.58
Utilizing a t-table with 49 levels of opportunity (test size - 1) and an importance level of 0.05, the basic t-esteem is ±2.009.
Since the determined t-worth of - 2.58 is not exactly the basic t-worth of - 2.009, we can't dismiss the invalid hypothesis. This really intends that there isn't sufficient proof to recommend that there is a massive distinction in medical services costs per worker between last year and this year with the agreement with Grimms Wellbeing Upkeep Association having no effect.
