Answer:
$41.50 profit
Step-by-step explanation:
First, 1.25x48=60
Second, 60-18.50=41.50
Question-
A team math contest has $11$ teams of $6$ students each. Before the contest begins, every student high-fives every other student who is not on their team. How many high-fives take place in all?
Answer:
The number of favorable outcomes is 5
Step-by-step explanation:
<u><em>The correct question is</em></u>
How many favorable outcomes are expressed in the fraction 5/12
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the event space is the number of outcomes in the event you are interested in or the number of favorable outcomes
The size of the sample space is the total number of possible outcomes
In this problem we have
therefore
The number of favorable outcomes is 5
The total number of possible outcomes is 12
H(t)=-16t^2+15t+12
(e)
maximum height is reached when h'(t)=-32t+15=0, or tm=15/32 seconds.
maximum height reached = h(tm)=h(15/32)=-16(15/32)^2+15(15/32)+12
=993/64 ft
=15.516 ft.
(f) when Greg reaches water, h(t)=0=-16t^2+15t+12
Solve for t using quadratic formula,
t=[-15+/- sqrt(15^2+4*12*16)]/(2*-16)
=-0.516s or 1.4535s.
Reject negative root so
Greg reaches water at t=1.4535 seconds.
