The linear function that represent the cost per pound of the gummy bears in x years after 2000 is given by:
y(x) = 0.0425x + 0.38
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, which can also be interpreted as the initial value of the function.
In this problem, we have that:
- In 2000, Carl’s Candy Shop sold gummy bears for $0. 38 per pound, hence b = 0.38.
- In 2008 they cost $0.72 per pound, that is, in 8 years there was an increase of $0.34 per pound, hence the slope is m = 0.34/8 = 0.0425.
Thus, the function is:
y(x) = 0.0425x + 0.38

Determine the probability of drawing red and green without replacement
This is calculated as follows:
We used Total - 1 because it's a probability without replacement:
<em>Hence, the required probability is 1/11</em>
Answer:
The correct option is D.
Step-by-step explanation:
Given the figure in which UV=XW, UX=VW and ∠UXW=∠UVW.
We have to tell why UW=UW and ∠UVW=∠WXU.
As the reflexive property of equality states that a value is equal to itself.
Hence, in quadrilateral UVWX,
UW is equal to UW by reflexive property
∠UVW=∠WXU as given
hence, UW=UW and ∠UVW=∠WXU by reflexive property and given in diagram.
The correct option is d)
The sum of all the measurements is just the average times the number.
So if the average of all 92 is 7 the sum of those is
The average of the last two is 7.2 so their sum is
That means the sum of the first 90 is
so the average of the first 90 is
cm
