Step-by-step explanation:
Answer:
And using the probability mass function we got:
And adding the values we got:
The best answer would be:
D. 0.377
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For this case in order to pass he needs to answer at leat 6 questions and we can rewrite this:
And using the probability mass function we got:
And adding the values we got:
The best answer would be:
D. 0.377
Answer:
78%
Step-by-step explanation:
Answer:
61
Step-by-step explanation:
Arc AC = 180
Arc DC = 58
Arc AC = Arc AD + Arc DC
180 = Arc AD + 58
122 = Arc DC
Tangent Chord Angle = 1/2Intercepted Arc
Angle DBA = 1/2 Arc DC
Angle DBA = 1/2 (122)
Angle DBA = 61
