1 answer:
Answer:
120.
Step-by-step explanation:
It is given that a car rental sells accident insurance to 28% of its customers.
Total number of customers = 430
We need to find the number of customers that are predicted to purchase insurance.
Required no. of customers = 28% of 430
Round to the nearest integer.
Therefore, the required no. of customers is 120.

Step-by-step explanation:
Let the -coordinate of
be
. For
to be on the graph of the function
, the
-coordinate of
would need to be
. Therefore, the coordinate of
would be
.
The Euclidean Distance between and
is:
.
The goal is to find the a that minimizes this distance. However,
is non-negative for all real
. Hence, the
that minimizes the square of this expression,
, would also minimize
.
Differentiate with respect to
:
.
.
Set the first derivative, , to
and solve for
:
.
.
Notice that the second derivative is greater than for this
. Hence,
would indeed minimize
. This
value would also minimize
, the distance between
and
.
Therefore, the point would be closest to
when the
-coordinate of
is
.
