Answer:
21.759
Step-by-step explanation:
Given that :
Mean (m) = 25
Standard deviation (s) = 12.5
Sample size (n) = 40
α = 90%
The confidence interval is obtained using the relation:
Mean ± Zcritical * s/sqrt(n)
Zcritical at 90% confidence interval = 1.64
25 ± 1.64 * (12.5/sqrt(40))
Lower boundary : 25 - 1.64(1.9764235) = 21.75866546
Upper boundary : 25 + 1.64(1.9764235) = 28.24133454
(21.759, 28.241)
Hence, lower bound of confidence interval is : 21.759

Answer:
Step-by-step explanation:
The given equality is
Take the term 
to the left hand side. This means the term 
will be divided by
Now since both the numerator and denominator have negative sign the value of fraction will be positive.
Now 
and 
So, the missing factor
Volume can be defined as the <u><em>capacity of a given container or a certain object.</em></u>
The radius of the cone is 2 inches.
From the question, we are given the following parameters:
<em>The height of the cone = 12 inches</em>
<em>The volume of the cone = 16 π in³</em>
The formula to find the<u> radius of the cone </u>is given as:
√3V/πh
= √ 3 x 16π / π x 12
= 2 inches
Therefore, the radius of the cone is 2 inches.
