By Assuming the denominator does not equal zero. a³b³/a⁴b equivalent expression is b⁴/a.
What is an equivalent expression?
Equivalent expressions are expressions that have the same result when they are simplified.
Two expressions are considered equivalent if they can be transformed into each other by applying mathematical operations such as simplification, combining like terms, or applying the properties of arithmetic and algebra.
Equivalent expressions can be used to solve problems more efficiently or to help understand complex mathematical concepts.
For example, simplifying an expression to its simplest form can make it easier to understand or perform further calculations with it.
Equivalent expressions can also be used to check the correctness of a solution to a problem, by verifying that the answer can be transformed into the expected result.
The given expression can be simplified as follows:
a³b³ / a⁴b = (a³/a⁴) * (b³/b)
a³/a⁴ = 1/a
b³/b = b²
Hence, By Assuming the denominator does not equal zero. a³b³/a⁴b equivalent expression is b⁴/a.

ow many ways can you select 7 cookies to buy from a bakery that sells cookies of 3 different flavors (oatmeal, chocolate chip, almond)? we assume that more than 7 cookies are displayed for each flavor. for example, one way is to choose 7 chocolate chip cookies
There are 2187 combinations to select 7 cookies from a bakery that sells cookies of 3 different flavors (oatmeal, chocolate chip, almond).
When selecting 7 cookies from a bakery that sells 3 different flavors, each cookie selected can be one of the 3 different flavors. This means that for the first cookie, there are 3 choices, for the second cookie, there are also 3 choices, and so on for the 7th cookie. This is known as the combinations formula and it can be represented as 3 x 3 x 3 x ... x 3 (3 being repeated 7 times).
Using the 3⁷ formula, we can calculate that there are 2187 ways to select 7 cookies from a bakery that sells cookies of 3 different flavors. This means that there are 2187 unique combinations of cookies that can be selected, assuming that more than 7 cookies are available for each flavor.

Identify the kind of sample that is described.
A football coach randomly selected the varsity or junior varsity team and then asks all players from that team their opinion on a new logo.
A. Stratified
B. Simple Random
C. Voluntary Response
D. Cluster
E. Systematic
The given sample of the randomly selected players from the teams as described is a stratified sample. Hence, the right answer is option A.
In a stratified sample, the population is divided into groups (or strata) based on some characteristic, and a random sample is selected from each group. In this case, the population is the football players, and the groups are the varsity and junior varsity teams. The coach randomly selects one of these teams and then asks all players from that team their opinion on a new logo.
This type of sampling is used when the population is divided into subgroups that are different in some way, and the researcher wants to ensure that these subgroups are represented in the sample. In this case, the coach wants to ensure that both varsity and junior varsity players are represented in the sample, as they may have different opinions on the new logo.
It's not a simple random sample because he selected the team first and then the players. Also, it's not a voluntary response sample because the coach is selecting the players.
It's not a cluster sample because the coach is not selecting the players based on location or geographic proximity, and it's not a systematic sample because he is not selecting the players based on the order in which they appear in a list or a database.

Using the theory vectors, find all possible fourth corners to parallelograms that have vertices (1,1), (4,2), and (1,3)
So, the possible fourth corners are (4,4) and (-2,2).
Given the three vertices of a parallelogram (1,1), (4,2), and (1,3), we can use vector algebra to find the fourth corner. We know that opposite sides of a parallelogram are parallel, and therefore have the same vector direction. We can use this property to find the vector pointing from one corner to another and then use this vector to find the fourth corner.
One possible method is:
Find the vector pointing from (1,1) to (4,2) by subtracting the coordinates of the first point from the coordinates of the second point: (4,2) - (1,1) = (3,1)Find the fourth corner by adding this vector to the third point: (1,3) + (3,1) = (4,4)Another possible method is:

A(3)=
A(4)=
A(10)=
Answer:
A(3) = 13
A(4) = 18
A(10) = 48
Step-by-step explanation:
This seems like a plug and play.
Starting with A(3). Everywhere you see an n, you'll replace it with a 3, as follows;
3 + (3-1)(5) = ?
We'll solve it step by step. First is 3-1. That's 2, bringing it to
3 + (2)(5).
2 times 5 is 10, bringing it to
3 + 10.
3 + 10 = 13, which concludes
A(3) = 13.
Now doing it for the remaining 2.
3 + (4-1)(5)
3 + (3)(5)
3 + 15
A(4) = 18
Last one...
3 + (10-1)(5)

find the area under the normal distribution curve whose mean is and whose standard deviation is using the given value for as a boundary.
The area under the normal curve with a mean of 20 and a standard deviation of 5 is 0.8413 when x = 25.
The area under the normal distribution curve is calculated using the z-score, which is the number of standard deviations a value is from the mean. To calculate the area under the normal curve for a given mean and standard deviation, one must use the formula:
Area = ½[1 + erf(z)]
Where erf is the Gaussian error function, and z is the z-score.
To calculate the area under the curve given a boundary x, the z-score must be calculated first. This is done using the formula:
z = (x - mean) / standard deviation
Substituting this into the formula above gives:
Area = ½[1 + erf((x - mean) / standard deviation)]
For example, if the mean is 20 and the standard deviation is 5, and the boundary value is x = 25, the area under the normal curve is calculated as follows:
z = (25 - 20) / 5 = 1
Area = ½[1 + erf(1)] = 0.8413
Therefore, the area under the normal curve with a mean of 20 and a standard deviation of 5 is 0.8413 when x = 25.

Which group cannot form 8 lines with an equal number of members in each line? A. 881 B. 440 C. 353 D. 224
Answer:
A. 881
C. 353
Step-by-step explanation:
In order to form 8 lines with each line having equal length, the total number of members has to be divisible by 8:
440/8 = 55, so 440 isn't the answer
224/8 = 28, so 224 isn't the answer
881/8 = 110.125. In addition, even numbers can't be divided evenly by odd numbers like 881, so A. 881 is the answer.
Same goes to 353 since 353 is also an odd number that can't evenly divide the even number 8. Hence, C. 353 is the answer as well.
Dr. Leona Williams, a well-known plastic surgeon, has a reputation for being one of the best surgeons for reconstructive nose surgery. Dr. Williams enjoys a rather substantial degree of market power in this market. She has estimated demand for her work to be: Q = 480 – 0.2P where Q is the number of nose operations performed monthly and P is the price of a nose operation. What is the inverse demand function for Dr. Williams’ services? What is the marginal revenue function? The average variable cost function for reconstructive nose surgery is estimated to be:
AVC = 2Q2 – 15Q + 400
where AVC is the average variable cost (measured in dollars), and Q is the number of operations per month. The doctor’s fixed cost per month is $8,000. If the doctor wishes to maximize her profit, how many nose operations should she perform each month? What price should Dr. Williams charge to perform a nose operation? How much profit does she earn each month?
We can conclude that -
The inverse demand function for Dr. Williams’ services is -Q = 5(280 - P)
For maximum profit, she should perform 4 operations.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is a story of Dr. Leona Williams who is a well-known plastic surgeon.
{ 1 } -
Dr. Williams estimated demand for her work is -
Q = 280 - 0.2P
Inverse of a function can be calculated by following the steps mentioned below -
Step 1 - Replace 'y' with 'x' and vice - versa.Step 2 - Rewrite the equation by solving for 'y'.Step 3 - Replace 'y' with f⁻¹(x).So, we can write -
P = 280 - 0.2Q
P - 280 = - 0.2Q
- (280 - P) = - 0.2Q
(280 - P) = 0.2Q
Q = (280 - P)/0.2
Q = 5(280 - P)
{ 2 } -
The average variable cost function for reconstructive nose surgery is -
AVC = 2Q² – 15Q + 400
Let AVC = A{Q}
For maximum profit -
d/dQ (A{Q}) = 0
d/dQ (2Q² – 15Q + 400) = 0
d/dQ (2Q²) - d/dQ (15Q) + d/dQ (400) = 0
4Q - 15 = 0
4Q = 15
4Q = 15
Q = 3.7
Q = 4 {approx.}
Therefore, we can conclude that -
The inverse demand function for Dr. Williams’ services is -Q = 5(280 - P)

Tarmu run 30 min and burned 170 calories. Write an equation that represents the number of calories,c, burned per min
c=170/30 is the equation that represents the number of calories,c, burned per min.
What is Division?A division is a process of splitting a specific amount into equal parts.
Given that Tarmu run 30 min and burned 170 calories
We need to find the equation that represents the number of calories, c, burned per min.
To find the calories burned in each minute we have to divide one hundred seventy by thirty.
c=170/30
c=5.66 cal/min
Hence, c=170/30 is the equation that represents the number of calories,c, burned per min.

What number gives a result of −4
when 11
is subtracted from the quotient of the number and 5
?
The required number is 42 which gives a result of −4 when 11 is subtracted from the quotient of the number and 5.
What is the Quotient?A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.
Let n be the number in question; then, we can write the word problem as an equation like this:
⇒ (n/6) - 11 = -4
Add 11 on both sides of the equation,
⇒ (n/6) - 11 + 11 = 11 - 4
⇒ (n/6) = 7
Multiply by 6 on both sides of the above equation, and we get
⇒ n = 42
Hence, the number is 42.
