Answer:
3 + 5i.
Step-by-step explanation:
(2−√−4)+(1+√−49)
√−4 = 2i and
√−49 = 7i.
So (2−√−4 + (1+√−49
= ( 2 - 2i) + (1 + 7i)
= 3 + -2i + 7i
= 3 + 5i.

Answer:
a)0.5611
b)0.1828
c)0.6217
d)0.4389
e)6.25
Step-by-step explanation:
Let's define the following event :
X : ''Calls involving a fax message''
The random variable X can be modeled as a Binomial random variable.
N ~ Bi(n,p)
N ~ Bi(25,0.25)
Where n is the sample and p is the success probability
Let's also define nCr as the combinatorial number :

The probability function for X is :

Where k is the number of success
a) 


b)
c) 
d)
e) They are asking us about the expected value for random variable X
In a Binomial random variable :
E(X) = μ = n.p
