D. Line A
A line which represents the line of best fit is: C. Line B.
What is a line of best fit?A line of best fit is sometimes referred to as a trend line and it can be defined as a statistical or analytical tool that is commonly used in conjunction with a scatter plot, in order to determine whether or not there is any form of association and correlation between a data set.
The characteristics of a line of best fit.In Mathematics, there are different characteristics that are used for determining the line of best fit on a scatter plot and these include the following:
The line should be very close to the data points as much as possible.The number of data points that are above the line should be equal to the number of data points that are below the line.By critically observing the scatter plot using the aforementioned characteristics, we can reasonably and logically deduce that line B represents the line of best fit because the data points are in a linear pattern.

Factor the expression 16a4 − b4 using the polynomial identity (x2 − y2) = (x − y)(x + y)
The factorization of given expression would be,
(4a^2)^2 - (b^2)^2= (4a^2 + b^2)(4a^2 - b^2)
In this question, we have been given an expression 16a^4 − b^4
We need to factor given expression using the polynomial identity

What is the Pythagorean theorem in plain English?
Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of this triangle's three sides.
Given that
hypotenuse is 53 cm
base is 28 cm
and it is a right angle triangle
Area = 1/2 x Base x height
So by using Pythagorean theorem we can find its height
Height² + Base² = Hypotenuse²
Height² + 784 = 2809
Height² = 2024
Height = 45 cm
Area = 1/2 x 28 x 45

if a person usually ate 2 ounces of lean meat at lunchtime and decided to substitute cooked lentils instead, how much of the lentils would the person need to eat?
If a person substitutes 2 ounces of lean meat by cooked lentils, the lentils that the person need to eat is ½ cup as both are protein.
Lean meat and lentils are among the sources of proteins in the food intake. Protein is found throughout the human body such as in muscle, skin, hair, bone, skin, hair, and every other body part or tissue. It manufactures the enzymes that power chemical reactions and the hemoglobin that carries oxygen in your blood. Protein is required by the body to help your body repair and make new cells. The foods that contain high content of proteins include lean meat, eggs, dairy products, lentils, etc. A half cup of cooked lentils provides 9 grams of protein, and 2 ounces of lean meat provides 8 grams of proteins. As the amount of protein provided by both is similar, a person can substitute one with another and maintain their protein intake.

how do you subtract mixed fractions?
Answer: Making them into improper fractions will really help you with subtracting mixed fractions! For example 2[tex]\frac{1}{5} \\[/tex] - 1[tex]\frac{1}{4}[/tex].
Making them into improper fractions will turn the expression into [tex]\frac{11}{5}[/tex] - [tex]\frac{5}{4}[/tex].
Turn the denominators into the greatest common multiple, so the greatest common multiple of 5 and 4 is 20. Meaning you multiply [tex]\frac{11}{5}[/tex] by 4 and [tex]\frac{5}{4}[/tex] by 5.
You now have [tex]\frac{44}{20} -\frac{25}{20}[/tex], which is much easier to work with. Simply subtract the numerators, and you should get [tex]\frac{19}{20}[/tex].

The intermediate step of equation x^{2}+32x+116=0 is (x + 16)² = 140
In this question, we have been given an equation x^{2}+32x+116=0

We can write given equation as,
x^{2}+32x= -116
Take the coefficient of x
k = 32
Divide it by 2
k/2 = 16
Square both sides
(k/2)^2 = 256
Add 256 to both sides of x² + 32x = -116
x² + 32x + 256 = -116 + 256

Q(t) = C/4t -1
Put a "y" in place of the "Q(t)":
y = C/4t -1
Change the t and y since each (t, y) has a corresponding (y, t) companion.
t = C/4y -1
Distribute t by multiplying into the bracket to find y.
t × 4y -1 = C
t × 4y - t = C
Add both sides of the equation together now.
t × 4y = C +t

Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain
The principal amount in account A was $250.09 and in account B it was $600.
Account B earned you the most interest the first month because $1.2 is higher than $0.7711.
What is the simple interest?
Simple interest is a quick and easy way to calculate the interest charge on a loan. Simple interest is calculated by multiplying the daily interest rate by the principal by the number of days between payments.
The formula for simple interest is expressed as
I = PRT/100
Where, P = the principal or initial amount of money invested.
R = interest rate
T = time
On account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years.
Using the formula:
I = PRT/100
[tex]6.94 = \frac{P(3.7)(0.75)}{100} \\\\6.94 = 0.02775P\\\\P=250.09[/tex]
On account B,
I = $39.60
R = 2.4%
T = 33 months = 33/12 = 2.75 years
Using the formula:
I = PRT/100
[tex]39.60= \frac{P(2.4)(2.75)}{100} \\\\39.60 = 0.066P\\\\P=600[/tex]
To find the account that earned more interest in the first month we have to divide the interest by the number of months.
For account A,
6.94/9 = $0.7711
For account B,
39.60/33 = $1.2
Hence, the principal amount in account A was $250.09 and in account B it was $600.
