Answer:
Step-by-step explanation:
The situation is a case of matched or paired samples since the samples are dependent. The two measurements are drawn from the same pair of individuals The parameter that is tested using matched pairs is the population mean and this is what teacher intends to use a hypothesis test for.
The correct option is
A) She gives each student a pretest. Then she teaches a lesson using a computer program. Afterwards, she gives each student a post test. The teacher wants to see if the difference in scores will show an improvement.
When it says "the subject", it only means you need to isolate the x, or solve for x. To do that, we have to get the x by itself. But how can we do that? We'll have to get rid of that pesky -5. Well, what can we do to -5 to get to 0? Of course -- Add 5!
b=x-5
+5
But whatever we do to one side of the equation, we have to do to the other.
b=x-5
+5 +5
We're left with b+5=x. There's your answer!

Answer:
The height of the tent = 3 feet
Step-by-step explanation:
Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 36 feet^3. Syrus isn't sure if the tent will be tall enough for him to sit up inside. The tent is the shape of triangular prism whose length is 6 feet and width is 4 feet. What is the height of the tent?
Given:
Length of the tent = 6 feet
Width of the tent = 4 feet
Volume of the tent = 36
Solution:
Since the ten is in shape of triangular prism, so the volume of traingular prism is given as:
where represents length, represents width and represents height of the prism.
Plugging in the know values of the dimension of the tent and the volume to find the height of the tent.
Simplifying.
\frac{36}{12}=\frac{12h}{12}
3=h
∴ h=3
Thus, the height of the tent = 3 feet
