Answer:
a) It cannot be concluded at the 99% confidence level that there is actually a difference between the true mean comfortable room temperatures for the two groups.
Step-by-step explanation:
Answer:
I will explain the equation
in a graph, the slope will look like this
The Y Intercept is -1, and the slope is -3, as in it will go downward
For every 1x, the slope will go downward by 3.
Answer:
Infinitely many solutions (the lines are identical)
Step-by-step explanation:
Let's start by getting each equation into slope intercept form (y=mx+b)
-14x-14y=28
-14x-28=14y
-x-2=y
and
7x+7y= -14
7x+14= -7y
-x-2=y
We can see that these two lines are identical which means that there are an infinite amount of answers
Y=6 x is 3 and y is 6 the answer is 6 from the y axis
