Answer:
a. 0.50
Step-by-step explanation:
The standard error of the mean is the standard deviation of the population divided by the square root of the sample size.
In this problem, we have that:
Standard deviation of the population: 6 hours
Sample size: 144
Square root of 144 is 12.
So the standard error of the sample mean is 6/12 = 0.5.

Answer:
70
Step-by-step explanation:
The angle at the bottom right of the triangle is linear with the 105, so it is 180 - 105 = 75
The top angle of the triangle is an alternate interior angle with the 35 degrees, so it is also 35.
75 + 35 = 110
x = 180 - 110 = 70
Answer:
6.5
Step-by-step explanation:
The midpoint of the line is (-1,7). If you draw a line between that and (1.6), you’ll pass through the y-axis at 6.5.
