The correct answer is F. None of the above. Data analysts prefer to deal with random sampling error rather than statistical bias for non of the reasons.
Data analysts prefer to deal with random sampling error rather than statistical bias because random sampling error is a type of error that occurs by chance and can be reduced through larger sample sizes or better sampling methods.
On the other hand, statistical bias occurs when there is a systematic error in the data collection or analysis process, leading to inaccurate or misleading results. While there are methods for managing and reducing statistical bias, it is generally considered preferable to avoid it altogether through careful study design and data collection. Being fair or avoiding accusations of bias may be important ethical considerations, but they are not the primary reasons for preferring random sampling error over statistical bias.Thus, Data analysts prefer to deal with random sampling error rather than statistical bias for non of the reasons.

Step-by-step explanation:
First, we try to find the slope of the table. We can do this by doing the following- [tex]\frac{Change \ in \ y }{Change \ in \ x}[/tex]
When we do this, we find that the slope (or the change in y / change in x) is equal to 5.27
Now we subtract this from the slope of the price of steak at Store B which is 9.72
[tex]9.72-5.27 = 4.45[/tex]

A jar of marble ha 5 blue marble, 3 red marble, and 4 green marble. What i the probability of drawing a marble that i blue, and then, after replacing it, drawing a marble that’ green
The probability of drawing a marble that is blue, and then, after replacing it, drawing a marble that’ green is 5/36.
In the given question, a jar of marble has 5 blue marble, 3 red marble, and 4 green marble.
We have to find the probability of drawing a marble that is blue, and then, after replacing it, drawing a marble that’ green.
Total number of marbles = 5 + 3 + 4
Total number of marbles = 12
The probability of choosing the blue marble = Number of Blue Marble/Total number of marble
The probability of choosing the blue marble = 5/12
Now replacing the marble blue and getting the green marble = Number of Green Marble/Total number of marble
Now replacing the marble blue and getting the green marble = 4/12
Now replacing the marble blue and getting the green marble = 1/3
The probability of getting blue marble then green marble = The probability of choosing the blue marble × The probability of choosing the green marble
The probability of getting blue marble then green marble = 5/12 × 1/3
The probability of getting blue marble then green marble = 5/36

Judy need 2/3/4 yard of flannel to ew a kirt. She obtain 3/8 yard of flannel from the local market. How much more fabric doe he need to titch the kirt?
Judy needs 1 5/8 yards area more of flannel to stitch the kirt.
To find how much more fabric Judy needs, we need to subtract the amount she already has from the amount she needs.
Judy needs 2/3 yard of flannel
Judy has 3/8 yard of flannel
To subtract these fractions, we first need to convert them to the same denominator.
2/3 yard = 4/6 yard
3/8 yard = 6/8 yard
4/6 yard - 6/8 yard = (24 - 24)/48 = 0/48
To simplify, 0/48 = 0
Therefore, Judy needs 0 yards more of flannel.
However, Judy needs 2/3 yard of flannel to stitch the kirt. Since she has 3/8 yard, we can subtract the two to find how much more fabric she needs.
2/3 yard - 3/8 yard = (16 - 12)/24 = 4/24
To simplify, 4/24 = 1/6
Therefore, Judy needs 1 1/6 yards area more of flannel to stitch the kirt.

DECIDING WHETHER A FUNCTION IS INCREASING, DECREASING, OR CONSTANT
Some recent studies suggest that a teenager sends an average of 60 texts per day.[2] For each of the following scenarios, find the linear function that describes the relationship between the input value and the output value. Then, determine whether the graph of the function is increasing, decreasing, or constant.
The total number of texts a teen sends is considered a function of time in days. The input is the number of days, and output is the total number of texts sent.
A teen has a limit of 500 texts per month in his or her data plan. The input is the number of days, and output is the total number of texts remaining for the month.
A teen has an unlimited number of texts in his or her data plan for a cost of $50 per month. The input is the number of days, and output is the total cost of texting each month.
According to given data, we can prove that Statement 1 is increasing function, Statement 2 is Decreasing Function, and Statement 3 is Constant Function.
1. The linear function that describes the relationship between the input value (number of days) and the output value (total number of texts sent) is y = 60x, where y is the total number of texts sent and x is the number of days. The graph of this function is increasing because as the number of days increases, the total number of texts sent also increases at a constant rate of 60 texts per day.
2. The linear function that describes the relationship between the input value (number of days) and the output value (total number of texts remaining for the month) is y = 500 - 60x, where y is the total number of texts remaining for the month and x is the number of days. The graph of this function is decreasing because as the number of days increases, the total number of texts remaining for the month decreases at a constant rate of 60 texts per day.
3. The linear function that describes the relationship between the input value (number of days) and the output value (total cost of texting each month) is y = 50, where y is the total cost of texting each month and x is the number of days. The graph of this function is constant because the cost of texting is the same regardless of the number of days.

(x + a) (x + b) = x2 + (a + b)x + ab
(x + a) (x – b) = x2 + (a – b)x – ab
(x – a) (x + b) = x2 + (b – a)x – ab
(x – a) (x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab (a + b)
(a – b)3 = a3 – b3 – 3ab (a – b)

What is continuous compound interest?Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to a period of time.
Formula of continuous compound interest rate;
P(t) = P₀[tex]e^{rt}[/tex], where P₀ is the principal amount, r is the interest rate and t is the time period.
Given:
A customer uses a store credit card to purchase a boat for $10,500.
The store credit card offers an annual interest rate, compounded continuously, of 18.99% with no payments due for the first two years.
That means,
P₀ = $10500, r = 18.99 and t = 2.
So,
P(t) = P₀[tex]e^{rt}[/tex]
Substituting the values,
P(t) = (10500)[tex]e^{(0.1899)(2)}[/tex]
P(t) = (10500)(1.46199)
P(t) = 15350.917
P(t) = $15350.92
Therefore, the final amount is $15350.92.

Which of the following is a trinomial ?(а) -7z(b) z² – 4y²(c) x²y – xy² + y²(d) 12a – 9ab + 5b – 3.
As we know that Trinomial means a polynomial with three terms.
Therefore, option (c) x²y -xy² +y² is correct.
Given polynomials are:
(а) -7z
(b) z² – 4y²
(c) x²y – xy² + y²
(d) 12a – 9ab + 5b – 3.
To Find : Which one is Trinomial.
Monomial:
A monomial is defined as an expression with one non-zero term. It consists of various parts such as variables, coefficients and orders. A unary variable is the character it contains. A coefficient is a number that is multiplied by a monomial variable. The monomial degree is the sum of the exponents of all variables.
Binomial:
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-no question and each has a Boolean result of Success (probability p) or failure. A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a series of results is called a Bernoulli process. For one trial, d. H. n = 1, binomial distribution is Bernoulli distribution. The binomial distribution is the basis for the common binomial test of statistical significance.
Trinomial:
A ternary expression is an algebraic expression with three terms. An algebraic expression consists of variables and constants in one or more terms. These expressions use symbols or operations such as +, –, ×, and ÷ as separators. Trinomials fall into this algebraic expression, along with monomials, binomials, and polynomials.
In Short :
Monomial - A polynomial with single Term
Binomial - A polynomial with 2 terms
Trinomial - A polynomial with 3 terms
Based on the information:
(а) -7z only one term hence Monomial
(b) z² – 4y² Two terms Hence Binomial
(c) x²y – xy² + y² Three terms hence Trinomial
(d) 12a – 9ab + 5b – 3. Four terms hence quadrinomial.
So correct option is c) x²y – xy² + y²
