Equation to show the proportional relationship between the regular price, r, of an item and its sale price, s is 10s -7r=0.
<h3>What is sale price?</h3>
A sale price is the discounted price at which goods or services are being sold. This price is usually offered for a limited period of time, typically to spur sales during a slow period or to sell off excess inventory.
Let the regular price be r and sale price be 's'
Since price of every item reduced by 30%.
So, sale price will be
% of r
s= r - 0.3 r
s= 0.7 r
s-0.7r=0
or, 10s -7r=0
Thus, equation shows the proportional relationship between the regular price, r, of an item and its sale price, s :10s -7r=0

Answer:
Given below
Step-by-step explanation:
First we state the objective of our research, whether what we have to find out.
Then we choose a random sample.
Then we collect the data about it, sort it and find out the statistics like mean etc.
The fourth step is to infer population parameters based on sample statistics.
The last step is to draw conclusions whether our objective is proved or not or what we can deduce from the results.
In this experiment the steps are as follows.
1) it is required to study how many hours households have internet usage.
2) The random sample in this experiment is 50000 households.
3) Finding out how many hours a day the household spends streaming video from the internet by asking from different households and then finding the mean etc.
4) The population mean prediction in this experiment depends on the sample mean.
5)The conclusion is drawn that how many hours a day the household spends streaming video from the internet.

Missing part of question
(a) (-3, 4) and (5, 4)
(b) (4, 5) and (4, -3).
Answer:
(a) (-3, 4) and (5, 4)
Zero slope
Horizontal line
(b) (4, 5) and (4, -3).
Undefined slope
Vertical line
Step-by-step explanation:
Solving (a): (-3, 4) and (5, 4)
Slope (m) is calculated as:
This gives
This line has a slope of zero.
When slope equals 0, then the line is horizontal
Solving (b): (4, 5) and (4, -3)
Slope (m) is calculated as:
This gives
<em>m = undefined</em>
This line has an undefined slope.
When the slope of a line is undefined, then the line is vertical
Answer:
Its a right isosceles triangle
