Answer:
The teacher select a sample of n =15 students. And he wanted to know if teaching a smaller class was more effective and students performed better, that means if 
and he obtaind a sample mean of 
.
Based on this the correct system of hypothesis are:
Null hypothesis: 
Alternative hypothesis:
And the best option for this case is:
a. H0:
vs. H1:
.
Step-by-step explanation:
For this case we have the following previous info given:
represent the true mean
represent the true deviation

Answer:
-3 or -1 is a valid value for x
Step-by-step explanation:
We start by cross multiplying;
So the expression becomes;
x^2 + 5x + 6 = 1(x + 3)
x^2 + 5x + 6 = x + 3
x^2 + 5x -x + 6-3 = 0
x^2 + 4x + 3 = 0
x^2 + x + 3x + 3 = 0
x(x + 1) + 3(x + 1) = 0
(x + 3)(x + 1) = 0
x + 3 = 0 or x + 1 = 0
x = -3 or x = -1
Answer:
The answer would be 24 1/2 miles.
Step-by-step explanation:
If she walks 3 1/2 miles everyday for one whole week, you would multiply 3 1/2 by 7 for each day of the week that she walks so 3 1/2*7 = 24 1/2.
Hope this helps :))
