Answer: The value of 
is 36.
Step-by-step explanation:
Given expression:
To find the value of at b= 5, we need to substitute the b=5 in the expression, we get
![6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36](https://tex.z-dn.net/?f=6%282%285%29-4%29%5C%5C%3D6%2810-4%29.......%5B%5Ctext%7Bsolve%20parentheses%7D%5D%5C%5C%3D6%286%29%5C%5C%3D6%5Ctimes6%3D36)
Therefore, the value of is 36, when b=5.
Answer:
H₀: μs = μf
H₁: μs ≠ μf
Step-by-step explanation:
Hello!
If the company wants to compare the sales of both departments "snacks" and "frozen foods" to see if there is any difference, the best is to compare the average number of sales of them.
Then the parameters of interest will be:
μs= average number of sales of the "snacks" department.
μf= average number of sales of the "frozen food" department.
The objective is to test if there is any difference between both departments, then the hypothesis should be two-tailed:
H₀: μs = μf
H₁: μs ≠ μf
I hope it helps!

Answer:
The volume of the metal used is 5277.9 cm³.
Step-by-step explanation:
The volume of a cylinder is given by:
Where:
r: is the radius
h: is the height = 50 cm
The volume of metal (
) can be found by subtracting the internal volume (
) from the external volume (
):
The external radius is given by the sum of the internal radius with the tickness:
Hence, the volume is:
Therefore, the volume of the metal used is 5277.9 cm³.
I hope it helps you!
