Answer:
Slope of the parallel line = -5/2
Slope of the perpendicular line = 2/5
Explanations:
The given equation of the line is:
The slope-intercept form of the equation of a line is:
y = mx + c
where m is the slope of the line
and c is the y-intercept
Comparing this to the given equation
m = -5/2
c = 9
Note:
When two equations are parallel, they have equal slope
When two equations are perpendicular, the product of their slopes equals -1, that is slope of the perpendicular line = -1/m
The slope of the parallel line = -5/2
The slope of the perpendicular line = -1 ÷ (-5/2)
The slope of the perpendicular line = -1 x (-2/5)
The slope of the perpendicular line = 2 / 5
Answer:
Option D is correct.
Step-by-step explanation:
Regression analysis determines the relationship between 2 or more variables by examining the influence of independent variables on a dependent variable.
Few requirements for regression analysis are like - quantitative data condition, the outlier condition, error independence etc.
The following is not a requirement for regression analysis:
D:The method for regression analysis line is not robust. It is seriously affected by a small departure from a normal distribution.
Answer:
1 bag of chips cost $1.25
Step-by-step explanation:
total money spent minus cost of soda = price of 2 bags of chips
$4.00- $1.50 = $2.50
2 bags of chips divided by 2 = price for one bag
$2.50 / 2 = $1.25
This is going to be an long answer, so I'm putting the answer first. y=3x-7
First, you have to find the equation of the line given. You can use point slope form for that. You can see that the slope is -1/3, and it goes through (2,2). So, the equation would be
y-2=-1/3(x-2)
Which simplifies to
y=-1/3x+8/3
Now, we can get on to finding the actual answer. The slope of a line perpendicular would be the negative reciprocal of the original slope. That just means you flip it and multiply it by -1. So, the slope of the new line is 3. Now you can use point slope form again and make an equation, which is
y+1=3(x-2)
Which simplifies to
y=3x-7
Please don't ask me why the slope is the negative reciprocal, or how they came up with the formula for the point slope form. I DON'T KNOW. If you want to know so bad you would give up chick-fil-A for the rest of your life, there's always google.
Answer:
21%
Step-by-step explanation:
Formula for this type of problem is
cross multiply
divide by 400
/400 /400
plug 21 into the original equation
simplify
.21 can be represented as 21%
