Answer:
"A" IS THE ANSWER
Step-by-step explanation:
I think that this an example of a paired t test. Since each student (subject) is given 2 treatments of the same material.
Y=13 Because a line equals 180. 180-11=169/13=13
x=8 because 180+22=202-4=198/11=18
Answer:
12:50 PM.
Step-by-step explanation:
We have been given that Craig’s school has 4 lessons in the morning and lesson 1 starts at 8:35. Each lesson is 60 minutes long. There is a break of 15 minutes between lesson 2 and 3.
We can see that lesson 1 will end at 9:35 AM and second lesson will end at 10:35 AM.
We have been also given that there is a break for 15 minutes between lesson 2 and 3. So third lesson will start at 10:50 AM as lunch break will end at 10:50 AM.
Third lesson will end 60 minutes after 10:50 AM that is 11:50 AM and fourth lesson will end 60 minutes after 11:50 AM that is 12:50 PM.
Therefore, 4th lesson will end at 12:50 PM.
$200 divided by 100 customers = 2$.
So, if he wants to make a profit of $200, he would have to make each customer pay $2. :)
