After a power failure the temperature in a freezer increased at an average rate of 1.3 degrees fahrenheit per hour. the total increase was 3.9 degrees fahrenheit. write and solve an equation to find the number of hours until the power was restored.

What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4? y-1=4(x-3) or y+3=4(x+1)

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Ahypothesis is: a the average squared deviations about the mean of a distribution of values b) an empirically testable statement that is an unproven supposition developed in order to explain phenomena a statement that asserts the status quo; that is, any change from what has been c) thought to be true is due to random sampling order da statement that is the opposite of the null hypothesis e) the error made by rejecting the null hypothesis when it is true
