Answer:
x=3 MT=36 MH=18
Step-by-step explanation:
The two triangles are the same, so 7x+8=10x-1
3x=9
x=3
MT=12x3=36
MH=36/2=18
Answer: The results do not represent the population because the sample does not represent professors from different areas.
Step-by-step explanation:
Since Traverion wants to find the answer to the question “How much money does the average college professor make?”
He only surveys 50 professors from the university in his hometown.
Although he should survey professors from different areas but he only perform his survey only a specific university in his hometown.
Therefore, the survey is biased as the sample size is too small.
Hence, The results do not represent the population because the sample does not represent professors from different areas.
Answer:
Area =
square units
Step-by-step explanation:
<u>Key skills needed: Area of a parallelogram</u>
1) This shape is a parallelogram, and the way to find the area of a parallelogram is:

A = area
b = base (the side at the bottom
h = the height ( the length that runs from one side to another and makes a right angle)
2) The base (b) would be 3x. The height (h) would also be 3x
3) This means A =
3 times 3 is 9 --> and x times x is 
Therefore the area is -->

Solution: We are given below data:

Now to find the mean deviation, we use the below formula:

Where:
represents the summation
X, represents the observation.
represents the mean
N represents the number of observation.


Therefore, the mean deviation is:

= 4
