Answer:
0.11% probability that you must ask 20 people to find one person without a social networking site
Step-by-step explanation:
We have these following probabilities:
75% probability that a millenial has a profile in a social netwok site.
25% probability that a millenial does not have a profile in a social network site.
What is the probability that you must ask 20 people to find one person without a social networking site?
The first 19 people have a social network site, each with a 75% probability.
The 20th person does not have a profile, with a 25% probability.
So
0.11% probability that you must ask 20 people to find one person without a social networking site
Answer:
Substitute the value of 7 into the variable x. Then solve the equation.
f(7) = 10 - 2(7)
f(7) = 10 - 14
<h2><em><u>
f(7) = -4 is the answer.</u></em></h2>
A. The area of the paralelogram is base • height so is (4x-2)•(2x-1)= 8x^2. -8x+2
b. X=2
A= 8•4-8•2+2= 32-16+2= 14 in^2
Answer:
Substitution or Elimination
Step-by-step explanation:
Substitution: x= -28/9 +7y/9
Elimination: x=x,y=4+9x/7
