Answer:
∠y = 62.5°
∠x = 27.5°
Step-by-step explanation:
z is right angle. ∠z = 90°
∠x = ∠y - 35
∠x + ∠y + ∠z = 180 {Angle sum property of triangle}
y - 35 + y + 90 = 180
y + y - 35 + 90 = 180 {Combine like terms}
2y + 55 = 180
2y = 180 -55 {Subtract 55 from both sides}
2y = 125 {Divide both sides by 2}
y = 125 /2
∠y = 62.5°
∠x = 62.5 - 35 = 27.5°

---------- None from computer programmers are introverts
Step-by-step explanation:
See comment for complete question
The question is an illustration of binomial probability where
--- marketing personnel
--- proportion that are extroverts
Using the complement rule, we have:
So, we have:
So, we have:
Recall that:
--- approximated
--- marketing personnel
--- proportion that are extroverts
So, we have:
---------- computer programmers
--- proportion that are introverts
So, we have:
Answer:
Step-by-step explanation:
Once
We have
We can proceed considering the common base of exponentials
