Solution:
Standard Error Formula:
SEx̄ = S / UNDERROOT N
where,
SEx̄ = Standard Error of the Mean
s = Standard Deviation of the Mean
n = Number of Observations of the Sample
SExĚ„ = 51.60/ âš21 = 11.26004314
So, standard error = 11.26004314
Answer:
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
The triangle PAB is a right triangle because the sum of ∠APB and ∠PAB is equal to 90 degrees
so
In the right triangle PAB
----> by SOH (opposite side divided by the hypotenuse)
substitute the given values
solve for AB
The price of this wrapping paper per inch is equal to $1,198.08.
<u>Given the following data:</u>
- Cost of wrapping paper = $12.48.
- Length of wrapping paper = 8 foot.
To determine the price of this wrapping paper per inch:
<h3>
How to solve the problem.</h3>
In this exercise, you're required to solve for the cost of an 8-foot roll of wrapping paper that costs $12.48. Thus, we would convert the length of this wrapping paper in foot to inch and then multiply by $12.48.
<u>Conversion:</u>
1 foot = 12 inch
8 foot = X inch
Cross-multiplying, we have:
X = 96 inch
For price per inch:
Price = $1,198.08

Surface of a cube=S(x)
S(x)=6x²
S(2 m)=6(2 m)²=6(4 m²)=24 m²
The surface of this cube is 24 m².
Volume of a cube=V(x)
V(x)=x³
V(2 m)=(2 m)³=8 m³
The volume of this cube is 8 m³.
