Final answer:
To solve the problem, three equations can be used: 25 ÷ 5 = ?, 5 × ? = 25, and 25 ÷ ? = 5.
Explanation:
The correct equations to help solve the problem are:
25 ÷ 5 = ?5 × ? = 2525 ÷ ? = 5To find the number of lettuce plants in each row, you need to divide the total number of lettuce plants, which is 25, by the number of rows, which is 5. So the first equation, 25 ÷ 5 = ?, will give you the answer. The second equation, 5 × ? = 25, can also be used to find the number of lettuce plants in each row by solving for the missing value. Finally, the third equation, 25 ÷ ? = 5, can be used as an alternative way to find the number of lettuce plants in each row.

Jerri was using a recipe for a large cake that required one-third of a tablespoon of cinnamon. Instead of making one large cake, Jerri decided to use the recipe to make four small cakes. How much should she use for each of the four small cakes?
A) 1/12 of a tablespoon
B) 1/3 of a tablespoon
C) 4/3 of a tablespoon
D) 1/4 of a tablespoon
If Jerri decides to make four small cakes out of a large cake recipe, she should divide the quantity of the required ingredient (in this case, cinnamon) by 4. Hence, for each small cake, she should use 1/12 of a tablespoon of cinnamon.
Explanation:The recipe Jerri is working with requires one-third of a tablespoon of cinnamon for a large cake. If she decides to use the same recipe to make four small cakes, she should divide the quantity of the cinnamon by 4, as the four smaller cakes together will make up the same quantity/volume as the one large cake.
The calculation can be done as follows: (1/3) tablespoon of cinnamon divided by 4 equals 1/12 tablespoon. Therefore, for each smaller cake, Jerri should use 1/12 of a tablespoon of cinnamon.
The correct answer is (A) 1/12 of a tablespoon.

Find the slope and y-intercept from the graph.
m=________ b=________
(m is slope)
(b is y-intercept)
Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is. Slope can be found using the ratio [tex]\frac{rise}{run}[/tex] between any two points that are on that line.
To get from one point on the graph to another point, we would rise 2 units which means go up to units and run -1 unit or go across 1 unit to the left.
The variable that is used to represent slope is m. So for this line we would say that m = -2
The base b represents the y-intercept of the line. The of the base as how far we are going up or down on the y-axis. Since we go up 5 units on the y-axis, we have a base of 5 so b = 5.
Remember, slope = rise/run.
We can use the points (-1, 7) and (3, -1) to solve.
_______
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
= -1-7/3-(-1)
= -8/4
= -2
_______
The y-intercept is given in the line but let's solve just to check.
y = mx + b
7 = -2(-1) + b
7 = 2 + b
7 - 2 = 2 + b - 2
5 = b
Now, we can see that y-intercept is 5.
_______
After solving for both the slope and y-intercept we can put this into slope-intercept form.
y = mx + b
y = -2x + 5

if the variables x and y have a strong positive correlation, what generally happens to y as x increases? what if x and y have a strong negative correlation?
If there is a strong positive correlation between "x" and "y" then when "x" increases, "y" tends to increase
If variables x and y have strong negative correlation then as "x" increases in value, "y" will decrease; similarly, if "x" decreases in value, "y" will increase
Solution:1) If the variables x and y have a strong positive correlation, what generally happens to y as x increases?
Let us first understand about strong positive correlation
Given that "x" and "y" has strong positive correlation
Correlation coefficients are used to measure the strength of the relationship between two variables.
Positive correlation:
Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
When one variable moves higher or lower, the other variable moves in the same direction with the same magnitude.
Therefore if there is a strong positive correlation between "x" and "y" then when "x" increases, "y" tends to increase
2) What if x and y have a strong negative correlation?
Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa.
Negative correlation is a relationship between two variables whereby they move in opposite directions.
If variables x and y have strong negative correlation then as "x" increases in value, "y" will decrease; similarly, if "x" decreases in value, "y" will increase

Determine the following values!!!!!
Answer:
x = 26 m∠DAB = 80° m∠ADC = 100°
Step-by-step explanation:
Given,
ABCD is a parallelogram in which AB ║ DC and AD║ BC.
m∠DAB = 4x-24
m∠ADC = 2x+48
Solution,
Since ABCD is a parallelogram so sum of two consecutive angle is 180°.
[tex]m\angle DAB+m\angle ADC=180\°\\4x-24+2x+48=180\°\\6x+24=180\°\\6x=180-24\\6x=156\\x=\frac{156}{6}=26[/tex]
Now substituting the value of x we get the value of ∠DAB and ∠ADC .
[tex]m\angle DAB=4x-24=4\times26-24=104-24=80\°[/tex]
[tex]m\angle ADC=2x+48=2\times26+48=52+48=100\°[/tex]
Thus the value of x is 26 and m∠DAB is 80° and m∠ADC is 100°

Step-by-step explanation:
Congruent supplements Theorem.
The symbol m∠LNM denotes the measure of the angle formed by points L, N, M. The 'm' stands for measure, '∠' denotes an angle, and LNM are the points forming the angle. In this context, m∠LNM is 72 degrees.
Explanation:The term m∠LNM refers to the measure of angle LNM. In mathematical notation, the symbol '∠' is often used to denote an angle, and LNM refers to the points forming the angle. For instance, if you have a triangle or any other polygon, and points L, N, and M are three vertices (corners) of the shape, then ∠LNM would be the angle at vertex N, formed by the intersection of line segments LN and NM. Given that m∠LNM is said to be 72°, this indicates that the measure of angle LNM is 72 degrees.

Explain how you can write an equation for a line with slope 1/2 that crosses the y-axis at the point (0,-1).
Answer:
y= 1/2x-1
Step-by-step explanation:
The equation of a line is y= mx+c
m represents the slope of the line
c represents the y-intercept
So we plug in our information into the equation.
The slope is 1/2 so y= 1/2x + c
The line crosses at (0,-1) which makes -1 the y-intercept as the line crosses at this point on the y-axis.
Therefore, y= 1/2x-1
To write an equation for a line with a slope of 1/2 that crosses the y-axis at the point (0,-1), we can use the slope-intercept form of a linear equation, y = mx + b. Substitute the given values into the equation to get y = (1/2)x - 1.
Explanation:To write an equation for a line with a slope of 1/2 that crosses the y-axis at the point (0,-1), we can use the slope-intercept form of a linear equation, which is y = mx + b.
Here, 'm' represents the slope and 'b' represents the y-intercept.
Since the slope is 1/2 and the y-intercept is at (0,-1), we can substitute these values into the equation to get y = (1/2)x + (-1) or y = (1/2)x - 1.
This equation represents a line with a slope of 1/2 and crosses the y-axis at the point (0,-1).

Describe a relationship modeled by the function f(x) = 4x3 − 72x2 + 320x
Answer:
A relationship modeled by the function f(x) = 4x³ - 72x² + 320x is the volume of a right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.Explanation:
To find a relationship modeled by the given function it is recommendable to factor it.
The function is:
[tex]f(x)=4x^3-72x^2+320x[/tex]The first step to factor it is to extract common factor 4x:
[tex]f(x)=4x(x^2-18x+80)[/tex]The second step is to factor the quadratic trinomial.
That is made by writting it as a product of two binomials, for which the two constant terms add up - 18 and their product is 80. Those terms are -10 and - 8; so the two factors are (x - 10) and (x - 8), and the factored form is:
[tex]f(x)=(4x)(x-10)(x-8)[/tex]Then, a relationship modeled by that polynomial is the volume of right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.
x is the desired (unknown) length 4x is 4 times the desired lengthx - 10 is 10 less than the desired lengthx - 8 is 8 less than the desired lengthThus, the volume of the prism is the product of the three factors:

Answer: y = 4.88 + 0.525x
The equation of the line of best fit for the data shown in the picture is y=0.894x+0.535
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
We have a data in the table:
Let's suppose the equation for the line is:
y = mx + c
Where m is the slope of the line and c is the y-intercept.
The value of m is given by:
[tex]\rm m = \frac{S_{xy}}{S_{xx}} }[/tex] and
[tex]\rm S_{xy} = \sum_{i=1}^{n}x_iy_i-\frac{(\sum_{i=1}^{n}x_i)(\sum_{i=1}^{n}y_i)}{n}[/tex]
[tex]\rm S_{xx} = \sum_{i=1}^{n}x_i^2-\frac{(\sum_{i=1}^{n}x_i)^2}{n}[/tex]
From the table(data is not mentioned we have assumed the data) the values of [tex]\rm \sum_{i=1}^{n}x_iy_i= 415[/tex], [tex]\rm {\sum_{i=1}^{n}x_i= 44[/tex], [tex]\rm {\sum_{i=1}^{n}y_i= 42[/tex],
[tex]\rm {\sum_{i=1}^{n}x_i^2= 438[/tex], and n = 5.
[tex]\rm S_{xy}= 415-\frac{44\times42}{5} \Rightarrow 45.4\\\\\rm S_{xx}= 438- \frac{44^2}{5} \Rightarrow 50.8[/tex]
[tex]\rm m = \frac{45.4}{50.8} } \Rightarrow 0.8937 \approx0.894[/tex]
For c we have to calculate the means of x and y for this:
[tex]\rm \bar{x} = \frac{\sum x}{n} \Rightarrow \frac{44}{5} \Rightarrow8.8[/tex]
[tex]\rm \bar{y} = \frac{\sum y}{n} \Rightarrow \frac{42}{5} \Rightarrow8.4[/tex]
Now, put the above values in the equation of a line to find the value of c
8.4 = (0.894)(8.8)+c
c = 0.5328 ≈ 0.535
Now the line is y = 0.894x+0.535
Thus, the line of best fit for the data shown in the picture is y=0.894x+0.535
