Answer:
Standard Deviation, σ = 6.5828058860438
Step-by-step explanation:
<u>Data Set:</u> 20, 11, 27, 13, 29, 20
The total numbers in the data set
Count, N = 6
The sum is all values in the data set is added up
20 + 11 + 27 + 13 + 29 + 20
Sum, Σx: 120
The mean is the sim / N
Mean, μ: 20
Answer: $11.60
Explanation: First, you want to do 15.1 - 9.3 to find what half of his weekly allowance is, and that would be 5.8, AKA $5.80. Next, you want to multiply that number by 2, which would be 5.8(2) to get 11.6, or your final answer, $11.60.
Answer: None
Step-by-step explanation:
In the given picture , there are two triangles and their corresponding angles are equal.
So by AAA similarity criteria they are similar. But there is no other information is given to prove that they are congruent.
[∵ we know that congruent are similar but similar triangles may not be congruent.]
Therefore, there is no sufficient information to prove them congruent by using any given postulate.
Hence, the answer is "None".
Answer:
Step-by-step explanation:
we know that
In the right triangle of the figure XYZ
Applying the Pythagorean Theorem
substitute the given values
square root both sides
