Answer:
Step-by-step explanation:
A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution. Pearson’s correlation coefficient returns a value between -1 and 1. The interpretation of the correlation coefficient is as under:
If the correlation coefficient is -1, it indicates a strong negative relationship. It implies a perfect negative relationship between the variables.
If the correlation coefficient is 0, it indicates no relationship.
If the correlation coefficient is 1, it indicates a strong positive relationship. It implies a perfect positive relationship between the variables.
A higher absolute value of the correlation coefficient indicates a stronger relationship between variables. Thus, a correlation coefficient of 0.78 indicates a stronger positive correlation as compared to a value of say 0.36. Similarly, a correlation coefficient of -0.87 indicates a stronger negative correlation as compared to a correlation coefficient of say -0.40.
Correlation Values
In other words, if the value is in the positive range, then it shows that the relationship between variables is correlated positively, and both the values decrease or increase together. On the other hand, if the value is in the negative range, then it shows that the relationship between variables is correlated negatively, and both the values will go in the opposite direction.
Write the equation of the line in slope-intercept for using y=mx+b
Answer:
y = 1/10x + 2
Answer:
y = 8x + 2
Step-by-step explanation:
Line is passing through the points (0, 2) and (1, 10)
Slope of line (m) = (10 - 2)/(1 - 0) = 8/1 = 8
y intercept (b)= 2
equation of the line in slope-intercept form using y=mx+b can be written as:
y = 8x + 2

Simplify the expressions by combining like terms
10r - 5r + 3r - 8r
Answer:
0
Step-by-step explanation:
Combine like terms, perform the operations with the coefficients of the variable, then write the variable.
10r - 5r + 3r - 8r
= 5r + 3r - 8r
= 8r - 8r
= 0
Answer:
0
Step-by-step explanation:
10r-5r=5r
5r+3r=8r
8r-8r=0

A representative sample of 60 students from a middle school is surveyed. Each student is asked what transportation method they use to get to school. The table below shows the responses.
Transportation Method Number of Students
Ride a bike 7
Ride a bus 20
Ride in a car 18
Ride a scooter 6
Walk 9
Complete the statements about all the middle school students based on the sample results.
It is expected that ___times as many students at the middle school ride in a car as walk to school.
It is expected that ___% of the middle school students ride a scooter to school.
In a random sample of 45 students at the middle school, it is expected that___students ride a bus to school.
In a random sample of 360 students at the middle school, it is expected that ___ students ride a bike to school.
HELP ME!! HURRY
Answer:
2, 10%, 15, 42
Step-by-step explanation:
18 / 9 = 2
Total number of students = 60
6 / 60 = 1/10 or 10%
1/3 ride the bus, so a sample of 45 would give 15
7/60 ride a bike so multiply by 360 = 42

Can someone explain how linear function is used in math and how it works
Answer:
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. ... It is also known as the slope and gives the rate of change of the dependent variable.

You know that multiplication can also be expressed as repeated addition. Why is it more difficult to use repeated addition when multiplying two mixed numbers than it is to use repeated addition when you are multiplying a mixed number by a whole number?
Answer:Let's start with the underlying fact. Multiplication simply is not repeated addition, and telling young pupils it is inevitably leads to problems when they subsequently learn that it is not. Multiplication of natural numbers certainly gives the same result as repeated addition, but that does not make it the same.

Solve this equation until you have the squared variable for the missing side length on one side of the equal sign and a rational number on the other.
The solution of the equation 9² + 12² = c² will be 15 and negative 15.
What is the solution to the equation?A designation of amounts to the unknown parameters that establish the equals in the formula is referred to as a result.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The equation is given below.
9² + 12² = c²
Simplify the equation, then the value of the variable c will be
c² = 81 + 144
c² = 225
c = ±√225
c = ±√(15)²
c = ± 15
Thus, the solution of the equation 9² + 12² = c² will be 15 and negative 15.
