Answer:
---- At least 5 from marketing departments are extroverts
---- All from marketing departments are extroverts
---------- 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:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
To solve for the time an object takes to hit the ground, the equation
<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>
(-2*60/-9.8)^½ = 3.50 seconds.
