Answer:
The lower bound for a 90% confidence interval is 0.2033
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The lower bound for a 90% confidence interval is 0.2033
Answer:
the number of diagonals can be found by n *n minus 3 by 2
a) the number of all possible diagonals drawn for having 7 side = 14 diagonals
b) the number of all possible diagonals drawn for having 10 side=35 diagonals
This result follows from the remainder theorem: the remainder upon dividing f(x) by x - c is exactly f(c).
So if

then the remainder upon dividing this by x - 2 is f(2), or

Answer:
