<u>Step-by-step explanation:</u>
A linear function : 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. a is the constant term or the y intercept. It is the value of the dependent variable when 
. b is the coefficient of the independent variable.
- rate of change: Ratio between two related quantities that are changing.
- slope: The ratio of the vertical and horizontal distances between two points on a line; zero if the line is horizontal, undefined if it is vertical.
In real life, we know that voltage is directly proportional to current , having resistance as a proportionality constant or more precisely slope of line :
, slope remains constant but , voltage is directly proportional to current .

Not sure:((((((( sorrryyyy
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The lower bound of the range is a = 51
The upper bound of the range is b = 710
The margin of error is 
Generally the standard deviation is mathematically represented as
=> 
=> 
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%20%5E2)
=> ![n = [ 1.96 * 164.75 }{10} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%201.96%20%20%2A%20%20164.75%20%7D%7B10%7D%20%5D%20%5E2)
