Answer:
Option C - Perfect square trinomial.
Step-by-step explanation:
Given : Polynomial 
To find : What pattern is represented by the polynomial?
Solution :
First we make the polynomial in factor form,
Polynomial 
Since, it is not factor clearly so try to make the square.
Taking 4 common,

Identifying the x and y terms in the identity,

Factor the perfect square trinomial,
Therefore, The pattern polynomial represent is perfect square trinomial.
So, Option C is correct.
The probability will be found as follows:
z-score is given by:
z=(x-μ)/σ
where:
mean-μ=9.3
standard deviation-σ=1.1
but
σ/√n=1.1/√70=0.1315
thus the z-score will be:
z=(9.1-9.3)/0.1315
z=-1.5209
thus:
P(x<9.1)=P(z<-1.5209)=0.0643
Answer:
he would have 145 dallors after baying his bills
Step-by-step explanation:
The probability of getting a 5 from the first rolling is 1/6. The probability of getting an even number is 1/2 (= 1/6 (for a 2) + 1/6 (for a 4) + 1/6 (for a 6)). As the two rollings are independent, you can just multiply two probability values to come up with a final answer. That is, (1/6)·(1/2) = 1/12.

<u>Answer:</u>

<u>Solution:</u>
Given: x=30
To solve: 
On substituting the value of x,

On dividing 30 and 5 we get,

So, the option is 15.
