Three main implications for linear regression analysis are as follows:
(1) determining the strength of the predictor, (2) foreseeing an impact, and (3) trend forecasting.
Linear regression:
A fundamental and popular technique for predictive analysis is linear regression. Regression's overarching objective is to look at two things:
Accurately can a group of predictor variables forecast an outcome (dependent) variable.
Factors in particular, and how do they affect the outcome variable, are strongly predictive of both.
There are three main functions for regression analysis:
Assessing predictor power, foreseeing an outcome, and trend forecasting.
The regression equation's simplest version, y = c + b*x, has one dependent and one independent variable.
where,
y is the estimated score for the dependent variable, c is a constant, b is the regression coefficient, and x is the estimated score for the independent variable.

The question is incomplete, here is the complete question
Michael split 3/4
pounds of candy among 8 people.
What is the unit rate in pounds per person?
Write your answer in simplest form
SOLUTION:
Micheal splits 3/4 candy among 8 people
Therefore the unit rate per pounds per person can be calculated as follows

How many units down does susan need to move to get to the fourth point on the number line a. 1/2 b. 3/2 c. 2 d. 4 e. 6
Answer:
e. 6
Step-by-step explanation:
Hello there!, since there is no prior information concerning the activities performed by Susan, I will explain what a number line is and try as much as possible to answer your question from the definition.
A number line is a line on which integers are usually drawn as points separated by a uniform distance. This way, the number line makes addition and subtraction easier, which is very useful when you want to teach someone these operations.
Now, let assume Susan starts from 0 on the number line, to get to the fourth point, Susan needs to move 4 blocks, where each block contains 10 units.
Now, let's assume that Susan is at the third block and the fourth unit, it will take Susan an additional 6 units to get to the fourth point.
NOTE: The solution to this question was provided based on assumption since no much information was given in the question.
Justin is evaluating the expression 12.5 + 3.8 x, when x is 7.9. 12.5 + 3.8 (7.9). 16.3 (7.9). 128.77. What was Justin's error? Justin should have multiplied 12.5 and 7.9 first. Justin should have added 12.5 and 7.9 first. Justin should have multiplied 3.8 and 7.9 first. Justin should have added 3.8 and 7.9 first.
Answer: Justin should have multiplied 3.8 and 7.9 first.
Step-by-step explanation:
Given the equation
12.5 + 3.8x
where, x = 7.9, the first thing that Justin's should have done was to multiply 3.8 and 7.9 first. This will be:
= 12.5 + 3.8x.
= 12.5 + 3.8(7.9)
= 12.5 + 30.02
= 42.52
Answer: (C) Answer: Justin should have multiplied 3.8 and 7.9 first.

Do the ratios 4/2 and 10/5 form a proportion? Yes or no
Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
[tex]\frac{4}{2}[/tex] [tex]\frac{10}{5}[/tex]
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.
If you have any questions or concerns feel free to message me.
Yes the ratios 4/2 and 10/5 form a proportion.

A boat which moves a 15 miles per hour without a current goes 36 miles upstream and 36 miles back in 5 hours. Find the speed of the current
Answer:
3 mph
Step-by-step explanation:
UPSTREAM:
distance = 36 miles ;
Speed = 15-c mph ;
TIME, t = distance / speed = 36/(15-c)
Downstream :
distance = 36 miles ;
speed = 15+c mph ;
time, t = 36/(15+c)
upstream time + downstream time = 5 hrs
36/(15-c) + 36/(15+c) = 5
36(15+c) + 36(15-c) = 5(15-c)(15+c)
1080 = 5(225 - c²)
1080 / 5 = 225 - c²
216 = 225 - c^2
216 - 225 = c²
-9 = c²
c = 3
