Answer:
8 is the only coefficient
Step-by-step explanation:

Answer:
See below
Step-by-step explanation:
The population is all American households
The sample is 2,541 of those American households
This is one of those problems where you'll sink like a rock if
you allow yourself to be blinded by all the useless, unnecessary,
irrelevant information in the first paragraph.
The ONLY information you need is:
-- You're chartering a bus for 1 day.
-- It costs $780 .
That's ALL .
(You don't even need to know that the bus has 55 seats.
You might need that for #8 - #12, but not for #6 or #7.)
_________________________
If the people on the trip are going to share the cost of the bus,
then the cost of each share depends on the number of people.
Less people ==> each one pays more.
More people ==> each one pays less.
Just like everybody in the office sharing the cost of
a birthday gift for the boss.
#6 and #7 should really be done in the reverse order ...
do #7 before you worry about #6.
Before you can fill in the table in #6, you absolutely need
to have the equation, whether or not you realize it.
The total cost is fixed . . . It's $780 .
If 2 people go on the trip, each one pays 780 / 2 .
If 3 people go on the trip, each one pays 780 / 3 .
If 4 people go on the trip, each one pays 780 / 4 .
If 5 people go on the trip, each one pays 780 / 5 .
.
.
If 10 people go on the trip, each one pays 780 / 10 .
.
.
If 20 people go on the trip, each one pays 780 / 20 .
.
.
If ' n ' people go on the trip, each one pays 780 / n .
.
. until the bus is full ...
.
If 55 people go on the trip, each one pays 780 / 55 .
.
If 56 people go on the trip, then you need another bus,
and it gets more complicated.
But up to 55, the price per person is (780 / the number of people).
<span> #7). P = 780 / n .
</span>Now, filling in the table in #6 is a piece 'o cake.<span>
</span>5 people. . . . . . . 780 / 5
10 people . . . . . 780 / 10
15 people . . . . . 780 / 15
20 people . . . . . 780 / 20
.
.
etc.
Just don't go past 55 people. The equation changes after that.
For ANY number of people, even hundreds, and ANY number
of buses, I think the equation looks something like this:
P = (785/n) · [ 1 + int(n/56) ] .
' int ' means ' the greatest integer in ... ', that is,
' throw away the fractional part of the quotient,
and use only the whole number '.
7.2 would be the quotient, because 237.6 divided by 33 is 7.2 .
A.
the starting point is where t=0
d(0)=-16(0)^2+96(0)+112
D(0)=112
started from 112 feet
b. max height is vertex
for
y=ax^2+bx+c
the x value of the vertex is -b/2a
so
D(t)=-16t^2+96t+112
t value of vertex is -96/(2*-16)=3
it reaches after 3 seconds
C. simpliy evaluate D(t) for t=3
D(3)=-16(3)^2+96(3)+112
D(3)=-16(9)+288+112
D(3)=-144+400
D(3)=256
max height is 256ft
