You first divide 414 by 46 to see how much it costs for 1 lb. After the calculation, you get 9 lb. Then you multiply that by 29 to get 261.

Graph the relationship between both parameters
First, calculate the area;
This implies that: (2, 120) i.e. 2 cans for 120ft^2.
So we have:
(0,0) and (2,120)
(0,0) implies that: 0 cans for 0 square feet
Calculate the slope:
The equation is:
So, we have:

Answer:
χ²R = 8.643
χ²L = 42.796
0.20 < σ < 0.45
Step-by-step explanation:
Given :
Sample size, n = 23
The degree of freedom, df = n - 1 = 23 - 1 = 22
At α - level = 99%
For χ²R ; 1 - (1 - 0.99)/2= 0.995 ; df = 22 ; χ²R = 8.643
For χ²L ; (1 - 0.99)/2 = 0.005 ; df = 22 ; χ²L = 42.796
The confidence interval of σ ;
s * √[(n-1)/χ²L] < σ < s * √[(n-1)/χ²R)]
0.28 * √(22/42.796) < σ < 0.28 * √(22/8.643)
0.2008 < σ < 0.4467
0.20 < σ < 0.45
The sum of any two rational numbers is a rational number. 0.166, 2/3, and 2 are all rational numbers, so adding them to 1/3 will produce another rational number.
That leaves 2π, an irrational number. The sum of a rational number and an irrational number is always irrational, so 2π will produce an irrational number when added to 1/3.
