Answer:
0.1091 or 10.91%
Step-by-step explanation:
We have been given that a particular telephone number is used to receive both voice calls and fax messages. suppose that 20% of the incoming calls involve fax messages and consider a sample of 20 calls. We are asked to find the probability that exactly 6 of the calls involve a fax message.
We will use Bernoulli's trials to solve our given problem.







Therefore, the probability that exactly 6 of the calls involve a fax message would be approximately 0.1091 or 10.91%.
Answer:
Im guessing this means 20% of 0.5, in that case it is 0.1
Step-by-step explanation:
you can use a calculator and put 0.2*0.5
But also in your head you can do whats 20% of 5, so what times 5 equals 5? 1
so 1/10 is 0.1 giving you your answer
I think is is:
7/20=35/100=0.35=35%
Hope I'm not wrong!
Hope this helps! :D
Answer:
x = - 4, x = - 
Step-by-step explanation:
To find the zeros let g(x) = 0, that is
(- 5x - 1)(2x + 8) = 0 ← in standard form
Equate each factor to zero and solve for x
- 5x - 1 = 0 ( add 1 to both sides )
- 5x = 1 ( divide both sides by - 5 )
x =
= - 
2x + 8 = 0 ( subtract 8 from both sides )
2x = - 8 ( divide both sides by 2 )
x = - 4
Thus
smaller x = - 4
larger x = -
