Determine whether the conclusion is based on inductive or deductive reasoning.Holly notices that every Saturday, her neighbor mows his lawn. Today is Saturday. Holly concludes her neighbor will mow his lawn.
Based on the explanation that is provided below, Holly's conclusion is based on inductive reasoning.
What is the difference between inductive and deductive reasoning?Inductive reasoning can be described as reasoning whose conclusion is based on a pattern of observations.
On the other hand, deductive reasoning refers to reasoning whose conclusion is based on a fact.
As Holly notices that every Saturday, her neighbor mows his lawn, this shows a pattern of observations.
This, therefore, implies that Holly's conclusion is based on inductive reasoning.

The three consecutive numbers are 58, 59 and 60.
Consecutive numbers are the numbers that follow each other continuously in a sequence from smallest number to largest number.
Let the first number = x
Let the second number = y
And Let the third number = z
As given in the question that the sum of the first and third number is 118, So we can write mathematically as
x + z = 118
The first and third numbers are 58 and 60 and their sum is 118.
The second number automatically will be 59.

Given g(x) = 1/3 (2x-1) 2, what is the value of g(8)?
By evaluating in x = 8 we can see that the value of g(8) is 45.
How to evaluate the function g(x)?
Here we have the function:
g(x) = (1/3)*(2x - 1)^2
We want to get the value of g(8), this means that we need to evaluate the function in x = 8.
To do this, we just need to replace the variable "x" in the equation by the number 8.
We will get:
g(8) = (1/3)*(2*8 - 1)^2 = (1/3)*(15)^2 = 3*15 = 45

3
The simple interest rate on the account is 13%
Here Sunil deposited $400 for one and a half years, and the interest he gets is $78. He deposits in at the simple rate of interest.
We know that the simple interest formula is
Simple interest = Principle × time × rate/ 100
It is given that,
simple interest = $78
time = 1 [tex]\frac{1}{2}[/tex] year = 3/2 year
Principle = $400
Let the rate of interest be r
So we have
78 =( 400 × 3/2 × r )/100
r =( 78 × 2×100) / (400 × 3)
r = 39%

factor this 4r³ - 3r²-4r +3
Answer:
(4r - 3)(r + 1)(r - 1)
Step-by-step explanation:
In order to factor the polynomial [tex]\sf 4r^3 - 3r^2 - 4r + 3[/tex], we can use various factoring methods.
In this case, we can use grouping.
Let's break down the expression and factor it step by step:
Group the terms in pairs:
(4r^3 - 3r^2) +(-4r + 3)
Factor out the greatest common factor from each group:
[tex]\sf r^2(4r - 3) - 1(4r - 3)[/tex]
Notice that both groups have a common factor of (4r - 3): and keeping remaining in bracket
[tex]\sf (4r -3)(r^2-1)[/tex]
Now, the expression r² - 1 can be factored further using the difference of squares:
(r + 1)(r - 1)
So, the fully factored form of the polynomial 4r³ - 3r² - 4r + 3 is:
(4r - 3)(r + 1)(r - 1)

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

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.

A function from a set X to a set Y assigns to each element of X exactly one element of Y.
We need to find the value of f ( - 1 )
We will do this by substituting the value of x as - 1
Put x = -1, we get that:
f ( x = -1 ) = ( - 1 ) + 4 ( - 1 )³
f ( - 1 ) = - 1 + 4 ( - 1 )
f ( - 1 ) = - 1 - 4

Find the surface area of that part of the plane 4x 5y z=74x 5y z=7 that lies inside the elliptic cylinder x225 y2100=1
Solve for [tex]z=f(x,y)[/tex] in the plane equation.
[tex]4x + 5y + z = 7 \implies f(x,y) = z = 7 - 4x - 5y[/tex]
Let [tex]E[/tex] be the set of points in the plane [tex]z=0[/tex] bounded by the ellipse [tex]\frac{x^2}{25}+\frac{y^2}{100}=1[/tex], i.e.
[tex]E = \left\{(x,y) ~:~ \dfrac{x^2}{25} + \dfrac{y^2}{100} \le 1\right\}[/tex]
Then the area of the plane bounded by the elliptic cylinder is
[tex]\displaystyle \iint_E dA = \iint_E \sqrt{1 + \left(\dfrac{\partial f}{\partial x}\right)^2 + \left(\frac{\partial f}{\partial y}\right)^2} \, dx \, dy \\\\ ~~~~~~~~ = \iint_E \sqrt{1 + (-4)^2 + (-5)^2} \, dx\, dy \\\\ ~~~~~~~~ = \sqrt{42} \iint_E dx \, dy[/tex]
which is simply √42 times the area of the ellipse in the plane [tex]z=0[/tex]. This ellipse has a minor axis of length 5 and a major axis of length 10, so its area is π•5•10 = 50π, and so the area of the plane in question is 50√42 π.
To confirm this result: In polar coordinates, with
[tex]\begin{cases}x(r,\theta) = 5r\cos(\theta) \\ y(r,\theta) = 10r\sin(\theta) \\ \frac{x^2}{25}+\frac{y^2}{100}=r^2\end{cases}[/tex]
the area element is
[tex]dA = \begin{vmatrix}\frac{\partial x}{\partial r}&\frac{\partial x}{\partial\theta} \\ \frac{\partial y}{\partial r} & \frac{\partial x}{\partial\theta}\end{vmatrix} \, dr \, d\theta \\\\ ~~~~~~~~ = \begin{vmatrix}5\cos(\theta)&-5r\sin(\theta)\\10\sin(\theta)&10r\cos(\theta)\end{vmatrix} \, dr \, d\theta \\\\ ~~~~~~~~ = \left(50r\cos^2(\theta)+50r\sin^2(\theta)\right)\,dr\,d\theta \\\\ ~~~~~~~~ = 50r \, dr \, d\theta[/tex]
The ellipse can be parameterized by
[tex]E = \left\{(r,\theta) ~:~ 0\le\theta\le2\pi \text{ and } 0\le r\le1\right\}[/tex]
so that the integral for the area of the ellipse in the plane [tex]z=0[/tex] is
[tex]\displaystyle \iint_E dA = \int_0^{2\pi} \int_0^1 50r \, dr \, d\theta \\\\ ~~~~~~~~ = 100\pi \int_0^1 r \, dr \\\\ ~~~~~~~~ = 100\pi\left(\frac12-0\right) = 50\pi[/tex]
