The explanation of given question is described below:
Here, the test of hypothesis states that

The test statistic is


= 2.1
According to the given data α = 0.05,
So, the major value is

(refer to the standard normal table)
.
Finally

Answer:
The inverse function is 
Step-by-step explanation:
The given function is
.
This function is only invertible on the interval,
.
To find the inverse on this interval, we interchange
and
.

We now make
the subject to get,



But the given interval is
, This implies that,
.

Answer:
radius = 9 inches

r = radius
Area = 254.4696 square inches
so we have:

so we have: r = 9 inches
4 )16= 4 DIVIDE 16 BY 4 TO GET 4 EVEN GROUPS OF 4 TEAMS
One possible inequality would be
1999-x<0.
If you subtract any year after he stepped down from 1999, the year he stepped down, the result will be a negative number.
