<u>Answer:</u>


<u>Step-by-step explanation:</u>
We have a parabola and a small line shown in the graph.
The parabola goes upto x = 2 but does not reach that very value. So x = 2 starts on the line above where x = 2 and ends just before x = 4.
Therefore, this function can be modeled by:


Answer:
The first our to the second hour
Answer:
The Math Club must sell at least 50 pies to reach the goal
The graph in the attached figure
Step-by-step explanation:
Let
x-----> the number of sold pies
we know that
The inequality that represent the situation is

Solve for x
Divide by 4 both sides


The solution is the interval ------> [50,∞)
All positive whole numbers greater than or equal to 50
In a number line the solution is the shaded area at right of x=50 (close circle)
The Math Club must sell at least 50 pies to reach the goal
using a graphing tool
see the attached figure
Answer:
Step-by-step explanation:
Given that of the volunteers coming into a blood center, 1 in 3 have O+ blood, 1 in 15 have O-, 1 in 3 have A+, and 1 in 16 have A-.
i.e. we can say out of the volunteers
O+ =
= 0.3333
O-=
=0.06667
A+=
=0.3333
A-=
=0.0625
Total = 0.795833
We can say remaining belong to B or AB.
%he probability that the person selected has________.
a. type O+ blood = 
b. type O blood= 
c. type A blood = 
d. neither type A nor type O blood = 
Answer:
A
