Let's assume your question is 1x^2-3=0
Explanation:
1x=x
x^2-3=0 . Add 3 to both sides
x^2=3 . Square root
x=+/-3
The positive solution to this equation is 3.
Images are focused by the lens onto the retina which is a face at the back of the eye upon which light sensitive cells (rods and cones) convert the incident light into electrical signals that are transmitted to the brain.
The fovea is a pit directly behind the lens on the retina that contains a concentration of light sensitive, closely packed cones (colour sensitive cells) and is responsible for sharp central vision.
Explanation:(a) Was this an observational study or an experiment? Explain your reasoning. Experiment, because certain variables were controlled (he sets the screen brightness to low and then starts a movie) to determine if iPhones last longer if the screen brightness is set to low, and it proves the cause and effect relationship.
(b) What is the explanatory variable and the response variable? Response Variable- To determine if iPhones last longer if the screen brightness is set to low Explanatory variable- he sets the screen brightness of 10 of the iPhones to high and starts a movie, then the other 10 to low and starts a movie.
(c) Was a random sample used to collect the data? Yes- “he selects a random sample of 20 brand new iPhones”
