Hi!
The answer is :
(y+2) * (y+9) = y^2 + 2y + 9y + 18 = y^2 + 11y + 18
Hope this helps!
<h3>Answer for problem 7 is B) Kelly</h3>
Since she has the most heads come up, making her chances to be best of getting heads.

<h3>Answer for problem 8 is D) Jessica</h3>
Divide each of the four values (102, 164, 75, 139) by 250 to get
102/250 = 0.408
164/250 = 0.656
75/250 = 0.300
139/250 = 0.556
We see that Jessica's empirical probability of 0.556 is closest to that of 1/2 = 0.500 which is the theoretical probability of getting heads.
Given:
The area model for 
.
To find:
The value of and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
The complete area model is shown below.
After adding all areas of the area model, we get
Therefore, the value of is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
