Answer:1. uses a related sample - repeated measures
2. . does not use a related sample--a
Step-by-step explanation:
Question 1.
step1 A repeated measure design is a design which measures a given sample repeatedly over a given time using different conditions or related measures.
step 2:In the treatment for compulsive hoarding, Here, measures are taken two times ie before and after treatment on the same 50 hoarders which shows a repeated measure, also the design is a within related sample of the same 50 hoarders to give measurement at different conditions of treatment for high and low hoarding scores so the design describes a related sample - repeated measures
Question 2:
step 1 ; An unrelated sample occurs when Samples being measured do not depend on each other
Step 2; 1st Sample for comparison by John are random lonely people and Second Sample are random non lonely people. so the two samples are independent on each other and will give different measurement based on quality of sleep. So the design does not use a related sample
Answer: 12
Step-by-step explanation:
6c + 11= 2c + 59
Collect like terms
6c - 2c = 59 - 11
4c = 48
c = 48/4
c = 12
I have attached the correct answer. Brainliest will be much appreciated!
Answer:

Step-by-step explanation:
The volume of the pyramid is given by:

where
is the area of the base and
is the height.
We know that the height is:

Thus we need to find the area of the square at the base.
The perimeter of the square is:

this means that the length of the sides of the square is :

Now we can find the area of the base which the area of the square:

and finally we find the volume:


Which rounded to the nearest tenth of a cubic centimeter is:
