Step-by-step explanation:
16. C, <AOB = 20
The total angle (<AOC) is equal to the sum of the angles inside of it (<AOB and < BOC).
<AOC= <AOB + <BOC
47=<AOB+27
<AOB=20
17. 24
Area of a square =
36=
s= 6
One side is 6
The perimeter of a square is 4(s)
4(6) = 24
Word of encouragement:
Good luck!
Solution :
a). The probability that the student will the 1st question after the 4th attempt.
P (correct in the 4th attempt)
=
= 0.01171875
b). The probability that the student will 3 questions after 10 total attempts.
P( X = 3) for X = B in (n = 10, p = 0.75)
=
= 0.0031
c). The mean and the standard deviation for the number of attempts up to when the students gets all the questions correct is :
There are = 6 success, p = 0.75.
Therefore, this is a case of a negative binomial distribution.
= 8
So,
= 1.6330
