A group of 6 students was asked how many hours did you watch television last week?' Here are there responses. 5,5,5,7,16,11 Find the mean number of hours for these students If necessary, round your answer to the nearest tenth.

The mean number of hours is 8.2

Step-by-step explanation: The observed data has been given as follows;

5,5,5,7,15,11.

The mean of the set of data can be derived as follows;

Mean = ∑x ÷ f

Where ∑x is the addition of all observed data and f is the number of data observed.

Mean = (5 + 5 + 5 + 7 + 16 + 11)/6

Mean = 49/6

Mean = 8.1667

Therefore the mean number of hours to the nearest tenth is 8.2 hours

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
