We need Vector ST which is just T - S
(7-3.4-2) = (4,2)
So now we need the perpindicular. The easiest way to do this, is to know that , in R2 that the perindicular is just the negatice inverse. So its (2,-4)
We have 7y = 4x + 14;
Then, y = (4/7)x + 2;
The slope of this line is 4/7;
Because another line is parallel with the first one, the chosen slope is 4/7.
Answer: 27.4 hours
Step-by-step explanation:
According to the given statement "A survey of 45 teens found that they spent an average of 25.6 hours per week in front of a screen (television, computer, tablet, phone, etc.)."
Since the word average is synonym of word mean.
Therefore, the sample mean must have the nearest value to the given average.
From the given options 27.4 is the nearest value to the average of 258.6.
Hence, the population mean = 27.4 hours.
