So first in a separate sheet of paper you have to look for how many members of fam and friends does Kimberly have. Then write down the amount of money she has in total.
Then subtract 120-36 cause she buys the book.
Which equals. 84
Then you have to subtract 84 from what I said at the beginning
Answer:
Find the exact value using trigonometric identities.
Exact Form: x=34
Decimal Form: x=0.75
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given
3
= 24 ( divide both sides by 3 )
= 8
Raise both sides to the power of 
x + 9 =
=
=
= 16 ( subtract 9 from both sides )
x = 7 → C
Answer: a $5 bill
Step-by-step explanation: add everything up together the pens add twice
Step-by-step explanation:
Given that,
a)
X ~ Bernoulli
and Y ~ Bernoulli 
X + Y = Z
The possible value for Z are Z = 0 when X = 0 and Y = 0
and Z = 1 when X = 0 and Y = 1 or when X = 1 and Y = 0
If X and Y can not be both equal to 1 , then the probability mass function of the random variable Z takes on the value of 0 for any value of Z other than 0 and 1,
Therefore Z is a Bernoulli random variable
b)
If X and Y can not be both equal to 1
then,
or 
and 

c)
If both X = 1 and Y = 1 then Z = 2
The possible values of the random variable Z are 0, 1 and 2.
since a Bernoulli variable should be take on only values 0 and 1 the random variable Z does not have Bernoulli distribution
