Answer:

Step-by-step explanation:
<u>Factored form of a parabola</u>

where:
- p and q are the x-intercepts.
- a is some constant.
Given x-intercepts:
Therefore:


To find a, substitute the given point (4, 8) into the equation and solve for a:




Therefore, the equation of the parabola in factored form is:

Expand so that the equation is in standard form:




50/250 = 1/5 = 0.20 = 20%
Answer: 20%
Answer:
I believe the answer is C :)
Step-by-step explanation:
Answer:
a) 16.66%
b) 5%
Step-by-step explanation:
a)
Since the teacher assumes each of the three possibilities are equally likely, then he assumes 33.33% to each one.
In this case the probability that you traveled to school that day by car would be
50% of 33.33% = (0.5)(0.3333) = 0.1666 = 16.66%
b)
In this case, the teacher would assume
90% ride on bicycle
0% take the bus
10% travel by car
So, in this case the probability would be
50% of 10% = (0.5)(0.1) = 0.05 = 5%
