Answer:
Number 1
Step-by-step explanation:
Because she travels quicker and he line is 3/4
Well 10%= 1/10 of 100% so you would Multiply 15$ by 10 to get the original price. E.G 15*10=150$
Slope: 1.5
y-intercept: -2
Explanation:
The slope is the number attached to 'x' in the equation. In this case, 1.5 would be the slope because it's attached to x.
The y-intercept is the constant the number not attached to any variables. In this case, -2 is all by itself.
Hope that helps!

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.
The variables are the row and column labels (except "total"). The appropriate choice is
... period number and study group number
