4. Which equation is perpendicular to the line y = 3 and passes through the point (-1,3)
The equation that is perpendicular to the line is x = -1
How to determine the equation that is perpendicular to the line?The line equation is given as
y = 3
The point is also given as:
(x, y) = (-1, 3)
A linear equation is represented as
y = mx + c
Where m represents the slope
This means that y = 3 can be represented as
y = 0x + 3
So, the slope is 0
Since the slope is 0, the equation of the perpendicular line must be
x = xt
Where
(xt, y) = (-1, 3)
By comparison, we have
x = -1
Hence, the equation that is perpendicular to the line is x = -1

in recent years, the numbers of cell phones and the numbers of pirates have both increased, so there is a correlation, or association, between those two variables. therefore, pirates cause increases in cell phones
Final answer:
When two variables are correlated or associated, it does not necessarily follow that one of the variables is the root cause of the other. Correlation does not always indicate cause.
What are the three forms of mathematical correlations ?The link between variables is described by correlation. It can be characterized as strong or weak, as well as positively or negatively.
Positive correlation occurs when two variables change in the same direction. There are three fundamental forms of correlation. The two variables fluctuate in opposite directions when there is a negative correlation. No association or meaningful connection exists between the two variables, hence there is no correlation.
The correlation coefficient aids in determining how closely two variables are related in a single figure. Finding the crucial variables that other factors depend on and comprehending economic behavior are both facilitated by correlation analysis.
Explanation:
A correlation test determines whether two variables are related. Nevertheless, just because two variables are traveling together does not necessarily mean they are connected. This is why the phrase "correlation does not indicate causation" is used frequently.
As two factors are connected or related, it does not necessarily imply that one of the variables is the main cause of the other. Correlation not always show cause.

What do we mean by matched pairs experiment?A matched pairs design is a type of experimental design in which study participants are matched based on key variables, or shared characteristics, related to the study's topic. Then, one member of each pair is assigned to the control group, and the other to the experimental group. A diet study involving 100 people is one example. Each subject would be matched with another of comparable age and weight. The pairs would then be divided into study groups, with each subject assigned to an opposing study group, diet or no diet.So, the given situation of a pesticide manufacturer is a perfect example of a matched-pairs experiment.

Answer:
8
Step-by-step explanation:
You times 4 by 4 since it's squared =16
You have to times 2 by 2 by 2 like this=8
2x2=4 4x2=8
then subtract them= 16-8= 8
put it over the line where 4 and 2 were
after you subtract 5 and 3= 2
than times 2 by the squared= 2x2= 4
times the 2 with 4= 8
put the 8 under the line so you can divide it
8 divided by 8 is 1
lastly, add 7 and 1= 8
=8
the answer is eight
four squared is 16 and two cubed is eight so sixteen minus eight is eight then five minus three is two then you would figure out what 2 squared us and its four so two times four is eight so the first part is eight over eight which is one and one plus seven in eight

Joe is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges an initial fee of 50 and an additional 50 cents for every mile driven.
Company B charges an initial fee of 35 and an additional 75 cents for every mile driven.
For what mileages will Company A charge no more than Company B?
Write your answer as an inequality, using m for the number of miles driven.
If the mileage is more than or equal to 60 miles Company A will charge no more than Company B.
The inequality is: 50 + 0.50m ≤ 35 + 0.75m.
What are inequalities?When both sides of a mathematical expression are not equal, an inequality exists. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.Inequality simply means that two things aren't equal. One of the items might be inferior to, superior to, greater than, or equivalent to the other things.Given:
m = number of miles driven.
initial fee of Company A = $50
initial fee of Company B = $35
additional fee of Company A = 50 cents = $0.50
additional fee of Company B = 75 cents = $0.75
then the inequality will be,
⇒ 50 + 0.50m ≤ 35 + 0.75m
⇒ 50 - 35 ≤ 0.75m - 0.50m
⇒ 15 ≤ 0.25m
⇒ m ≥ 15 /0.25
⇒ m ≥ 60
Therefore, if the mileage is more than or equal to 60 Company A will charge no more than Company B.

The rise-over-run formula for the slope of a straight line is the basis of the high-low method.
What is slope of a straight line?
The slope of a straight line by joining two points is the rise over run formula. The subtraction between the two points of the y-coordinates is called the rise. And the subtraction between the two points of the x-coordinates is called the run. The slope can be calculated by dividing the rise by run.
The slope of a line either goes in the upward direction or in the downward direction or left direction or right direction. It determines the direction of the line. When the straight line goes in the upward direction, it means the rising line and slope is positive. When it goes in the downward direction, it means a falling line and slope is negative.
