The ratio that does not illustrate a comparison from the items created in Suzanne's bakery is option D) 2:4 to signify cakes to pies.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, Suzanne was baking treats for her bakery's grand opening.
Since, She made 4 cakes with 8 cups of flour. She baked 2 pies and 3 dozen cookies.
Option A) 1:9 signifies a comparison of the number of cakes to the number of cookies.
Option B) 1:18 signifies a comparison of the number of pies to the number of cookies.
Option C) 2:1 signifies a comparison of the number of cakes to the number of pies.
However, option D) 2:4 does not illustrate a comparison between any of the items created in Suzanne's bakery.
This is because there are no given ratios for the number of cakes to the number of pies, or the number of cakes to the number of cakes plus pies.
Therefore, option D) is the correct answer.

What is the degree of the polynomial 5a^6bc^2+8d^5+7e^6f^2-10g^4h^7
Final answer:
The degree of the polynomial 5a⁶bc²+8d⁵+7e⁶f²-10g⁴h⁷ is 11, determined by the highest sum of exponents in any term of the polynomial, which is found in the term -10g⁴h⁷.
Explanation:
The degree of a polynomial is the highest exponent of its variables when it is expressed in standard form. To find the degree of the given polynomial 5a⁶bc²+8d⁵+7e⁶f²-10g⁴h⁷, we look at each term individually and sum the exponents of the variables within that term. The terms of the polynomial are:
5a⁶bc² with a degree of 6 + 1 + 2 = 9
8d⁵ with a degree of 5
7e⁶f² with a degree of 6 + 2 = 8
-10g⁴h⁷ with a degree of 4 + 7 = 11
Comparing the sums of the exponents, we see that the term -10g⁴h⁷ has the highest sum which is 11. Therefore, the degree of the given polynomial is 11.
Write the equation of the line with the given slope and y-intercept. Undefined slope, (0,-6)
Answer:
y = -6
Step-by-step explanation:
The y intercept is when x equals 0 , and as you can see in the coordinate, the x is zero so the y is -6. Since the slope is undefined, the answer is y=-6. I know that seems confusing, but when the slope is undefined, it just means that it is a straight line.

* Lets revise at first the order of operations
- The order of these operations is:
# Parenthesis
# Exponents
# Multiplication and Division which comes first from left to right
# Addition and Subtraction which comes first from left to right
- There is a word made from the first letter of each operation
PEMDAS to remember the order of operations
* Lets solve the problem
# Expression: 1
∵ 9(2 + 7 f)
- To simplify this expression multiply the bracket by 9
∵ 9(2 + 7 f) = 9 × 2 + 7 f × 9
∵ 9 × 2 = 18
∵ 7 f × 9 = 63 f
∴ 9(2 + 7 f) = 18 + 63 f
* Expression: 1 ⇒ 18 + 63 f
# Expression: 2
∵ 6 × 7 - 3² × 9 + 4³
- At first simplify exponent
∵ 3² = 9 and 4³ = 64
∴ 6 × 7 - 3² × 9 + 4³ = 6 × 7 - 9 × 9 + 64
- Solve the multiplication first
∵ 6 × 7 = 42
∵ 9 × 9 = 81
∴ 6 × 7 - 3² × 9 + 4³ = 42 - 81 + 64
- Solve 42 - 81 first because it comes first from left to right
∵ 42 - 81 = - 39
∴ 6 × 7 - 3² × 9 + 4³ = - 39 + 64
- Add them

4y + 9 = - 4y - 7. Please explain to me how to do it.
You want to keep the variable on the left and number on right.
So, we need to get rid of 9 and -4y. Let's start with 9.
4y+9=-4y-7
Subtract nine from both sides.
4y=-4y-16
Now add 4y on both sides.
8y=-16
Finally, divide both sides by 8 to get y=-?.
8y/8=-16/8
Therefore, the answer is y=-2.

Tickets to a basketball game cost $1.50
o a basketball game cost $1.50 for students and $3.25 for adults. The
school made $752.25 and sold 358 tickets. How many student and how many
adult tickets were sold?
Answer: Adult tickets = 123
Student tickets = 235
Step-by-step explanation:
Let x represent the number of adult tickets sold and
let y represent the number of student tickets sold
Then create two equations: Quantity & Cost
Cost: 3.25x + 1.50y = 752.25
Qty: x + y = 358
I am going to solve the system using the substitution method.
You can also solve using the elimination method.
Since x + y = 358
then y = 358 - x
Substitute y in the Cost equation with 358 - x and solve for x
3.25x + 1.50(358 - x) = 752.25
3.25x + 537 - 1.50x = 752.25
1.75x + 537 = 752.25
1.75x = 215.25
x = 123
Now substitute x with 123 into the Quantity equation to solve for y
x + y = 358
123 + y = 358
y = 235

Saleem says 45 × 32 is the same as (45 × 3) + (45 × 2). Explain Saleem’s error using words, numbers, and/or pictures.
Answer:
[tex]45\times 32 \neq (45\times 3) + (45\times 2)[/tex]
Step-by-step explanation:
First we will evaluate the value of the expressions.
[tex]45\times 32 = 1440[/tex]
[tex](45\times 3) + (45\times 2) = 225[/tex]
Hence, Saleem made an error in the evaluation of product of 45 and 32.
Saleem did a mistake in placing the values that is in 32, 3 is at ten's place so he should have multiplied 45 by 30 instead of 3.
The product can be evaluated in a correct manner as:
[tex](45\times 30) + (45\times 2) = 1350 + 90 = 1440[/tex]
You have $200 on a savings account and$100 in a checking account each week you add $50 to your savings account and $30 to your checking account Write an expression in simplest form that represents the total amount of money in both accounts after w weeks
Answer:
The expression is (80w+300)
Step-by-step explanation:
Let
y ----> the total amount of money in both accounts
s ----> the amount of money in saving account
c ----> the amount of money in checking account
w ----> the number of weeks
we know that

Write an equation of the line passing through each of the following pairs of points. a (−10, 4), (2, −5)
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 10, 4) and (x₂, y₂ ) = (2, - 5)
m = [tex]\frac{-5-4}{2+10}[/tex] = [tex]\frac{-9}{12}[/tex] = - [tex]\frac{3}{4}[/tex], thus
y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation of the line
To find c substitute either of the 2 given points into the partial equation
Using (2, - 5), then
- 5 = - [tex]\frac{3}{2}[/tex] + c ⇒ c = - 5 + [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]

what is the point slope form of a line with slope 3 that contains the point (2, 1)
Answer:
y - 1 = 3(x - 2)
y - 1 = 3x - 6
y = 3x - 5
Answer:
The point slope form of the line is y-1=3(x-2).
Step-by-step explanation:
If a line passes through a points [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex] .... (1)
where, m is slope.
It is given that the slope of a line is 3 and it passes through the point (2,1).
Substitute m=3, [tex]x_1=2\text{ and } y_1=1[/tex] in equation (1), to find the point slope form of the line.
[tex]y-(1)=(3)(x-(2))[/tex]
[tex]y-1=3(x-2)[/tex]
Therefore the point slope form of the line is y-1=3(x-2).

175,000
In Scientific notation
Answer:
1.75*10 to the power of 5
Step-by-step explanation:
start by moving the decimal over until only one number is in front of the decimal. this is because in scientific notation a number can't be higher than 9.
check how many places you move the decimal over (5). 1.75000 needs to be simplified (since that's the point of scientific notation) and can be simplified to 1.75.
the answer is 1.75 multiplied by ten to the power of digits the decimal moved (5) so the answer is 1.75*10 to the power of 5
175,000 in scientific notation is 1.75 × [tex]10^5[/tex].
To express the number 175,000 in scientific notation, follow these steps:
Move the decimal point in the number to the position after the first non-zero digit. For 175,000, this is 1.75.
Count the number of places the decimal point has moved to determine the exponent of 10. In this case, the decimal point moves 5 places to the left.
Combine the number obtained in the first step with the power of 10 determined in the second step. Thus, 175,000 in scientific notation is 1.75 × [tex]10^5[/tex].
This provides a concise representation of the number.
A set of bivariate data was used to create a least squares regression line. Which of the following is minimized by the line
A) the sum of the residuals
B) the sum of the squared residuals
C) the sum of the absolute value of the residuals
D) the influence of outliers
E) the slope
Answer:
B) The sum of the squared residuals
Step-by-step explanation:
Least Square Regression Line is drawn through a bivariate data(Data in two variables) plotted on a graph to explain the relation between the explanatory variable(x) and the response variable(y).
Not all the points will lie on the Least Square Regression Line in all cases. Some points will be above line and some points will be below the line. The vertical distance between the points and the line is known as residual. Since, some points are above the line and some are below, the sum of residuals is always zero for a Least Square Regression Line.
Since, we want to minimize the overall error(residual) so that our line is as close to the points as possible, considering the sum of residuals wont be helpful as it will always be zero. So we square the residuals first and them sum them. This always gives a positive value. The Least Square Regression Line minimizes this sum of residuals and the result is a line of Best Fit for the bivariate data.
Therefore, option B gives the correct answer.
The only correct option that is minimized by the least squares regression line is;
Option B; the sum of the squared residuals.
We want to find the correct option that minimizes the line. Let's look at the options ;
Option A; This statement is not correct because If you do a summation of the residuals, you would get a value of 0.
Option B; Since error needs to be minimized so that the line is a close to the points as possible and as seen above that the sum of the residuals is zero. Then before we sum them, we need to first of all square the residuals which will always give a positive value. Thus, since the Least Square Regression Line minimizes the sum of residuals, then this option is correct.
Option C; This option is wrong because the sum of the absolute values of the residuals is not a method for in creation of least squares regression line
Option D; This option is wrong because the influence of outliers has nothing to do with the topic in question.
Option E; This option is wrong too because slope has nothing to do with the topic in question.
