Explain the differences between a positive association and a negative association of bivariate data
Answer:
A positive association between two variables means that as the values of one variable increase, so do the values of the other variable. This is often represented by a line or curve that slopes upward to the right on a scatterplot. On the other hand, a negative association between two variables means that as the values of one variable increase, the values of the other variable decrease. This is often represented by a line or curve that slopes downward to the right on a scatterplot.

What is a percentage of 1 2?
There is no percentage of 1 2, as percentages are a fraction of 100 and 1 2 is not a fraction.
A percentage is a fraction of 100, while 1 2 is not a fraction. Therefore, there is no percentage of 1 2.A percentage is a way to express a number as a fraction of 100. For example, 25% is equivalent to the fraction 25/100. However, 1 2 is not a fraction, and therefore cannot be expressed as a percentage.1 2 can be expanded to 100 by multiplying both numerator and denominator by 50. 1 2 would then be equal to 50/100, or 50%.

154 is the same as the product of 158 and n, decreased by 132
Answer:
Equation: 154 = 158n - 132 n = 11/6
Step-by-step explanation:
Let's start by converting this into an equation. Some keywords to look for are "is" which means an equal sign (=), "product" which is multiplication (*), and "decreased" which means a minus sign (-):
So this is our equation: 154 = 158n - 132
Now we have to solve for n:
First, we add 132 to both sides to isolate the n more:
286 = 158n
Then to completely isolate the n, we divide both sides by 158
286
------ = n
156
n = 11/6, final answer.
An electrician account earn $1680 his account had a simple interest rate of 7.5% for the past four years what amount did he deposit four years ago
Thus, the amount he deposited four years ago is 5600.
A simple interest is what exactly?Simple interest is used to determine the amount of interest that will be charged on a sum of money at a specific rate and for a specific amount of time. The principal amount in simple interest does not change, in contrast to compound interest, which adds the interest from the principal of preceding years to determine the interest of the following year.
Here,
Given:
The amount of electrician account earned is 1680
thus total amount is = 1680 + x
where x is the principal amount
Interest rate = 7.5%
and total years = 4 years
Using formula
[tex]\frac{P*R*T}{100}[/tex]= Simple interest
=> 1680 = x*7.5*4/100
=>1680 =x * 30/100
=>1680* 100 /30 = x
=>5600
Thus, the amount he deposited four years ago is 5600.

Buying rental property is an investment option that carries a higher risk than some other options. However, the returns can be good. Assume you have purchased a single-family home that you intend to rent for $850 per month. You will have the following expenses:
The annual return of the investment is 31.1%.
Given that, person has purchased a single-family home that you intend to rent for $850 per month.
What is the return?A return, also known as a financial return, in its simplest terms, is the money made or lost on an investment over some period of time.
First find the amount earned per year:
= 850 x 12
= $10,200
The yearly expenses would be:
= (390 x 12) + (60 x 12) + (340 x 2) + 500 + (100 x 12)
= 4,680 + 720 + 680 + 500 + 1,200
= $7,780
The annual ROI is:
= (10,200 - 7,780) / 10,200 x 100%
= 31.1%

Write an equation of the line with a slope of 3 that passes through the points (1,5) and (-3,-7)
Answer:
y = 3x + 2
Step-by-step explanation:
y = 3x + c
substitute x and y with one of the points (ex: (1,5)):
5 = 3(1) + c
5 - 3 = c
2 = c
so
y = 3x + 2
To make sure this is correct, substitute x and y with the other point (ex: (-3,-7)):
-7 = 3(-3) +2
-7 = -9 + 2
-7 = -7
that means the equation is true and as it passes through both points.

The basic ratio is 63:81 but to simplify this ratio you can simplify each number as a multiplication of its factors.
63=3*3*7
81=3*3*3*3
Now find the factors they have in common and get rid of them.
63=3*3*7
81=3*3*3*3

What is Permutation?
In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order. In other words, if the set is already ordered, then the rearranging of its elements is called the process of permuting. Permutations occur, in more or less prominent ways, in almost every area of mathematics. They often arise when different orderings on certain finite sets are considered.
What is a Combination?
The combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases, it is possible to count the number of combinations. Combination refers to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection or k-combination with repetition are often used.
If the combination begins with an odd digit
We have 3 * 2 * 3 * 2 * 3 = 108 possible combinations
If the combination starts with an even digit
We have 2 * 3 * 2 * 3 * 2 = 72 possible combinations
So 108 + 72 = 180 possible combinations

The probability of one name drawn from the hat is 0.7 if a hat contains the names of seven boys and three girls.
We know that probability is defined as the division of number of favorable outcomes to the total number of outcomes.
In hat number of names of boys are =7 and
number of names of girls are =3
So, total number of names are =number of boys names + number of girls names
=>total number of names are =7+3
=>total number of names are=10
Now, number of boys are =7
So, count of favorable outcomes is =7 and total number of outcome is 10
=>Probability of choosing a boy name is =number of favorable outcome/total number of outcome
=>P(E) = 7/10

Types of Chi-square tests
You use a Chi-square test for hypothesis tests about whether your data is as expected. The basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true.
There are two commonly used Chi-square tests: the Chi-square goodness of fit test and the Chi-square test of independence. Both tests involve variables that divide your data into categories. As a result, people can be confused about which test to use. The table below compares the two tests.

Find the slope of the line that passes through (8,3) and (1,7)
Answer:
Slope = -4/7
Step-by-step explanation:
The slope of a line is determined by the formula m = (y2 - y1) / (x2 - x1), where m is the slope of the line, (x1, y1) and (x2, y2) are two points on the line. Plugging in the values from the given points, we get:
m = (7 - 3) / (1 - 8) = 4 / -7 = -4/7
Therefore, the slope of the line that passes through (8,3) and (1,7) is -4/7.
