<AEB and <DEC are equal so:
5x-10=3x+40
5x-3x=40+10
2x=50
x=25
<AEB= 5x-10
<AEB= 5*25-10
<AEB=115

Answer:
In mathematics, factorization or factoring is the breaking apart of a polynomial into a product of other smaller polynomials. If you choose, you could then multiply these factors together, and you should get the original polynomial (this is a great way to check yourself on your factoring skills).
Step-by-step explanation:
Answer:
(a) The expected score is 12.8
(b) The standard deviation is 3.2 and variance is 10.24
Step-by-step explanation:
Consider the provided information.
You are to take a multiple-choice exam consisting of 64 questions with 5 possible responses to each question.
Here n=64 p=1/5 and q=1-1/5=4/5
Part (a) we need to find the expected score on the exam.
Expected = np
Expected score = number of questions × P(right)

Hence, the expected score is 12.8
Part (b) Compute the variance and standard deviation of x.
Standard Deviation: 
Now calculate the standard deviation as shown:



Variance: 



Hence, the standard deviation is 3.2 and variance is 10.24
