The formula of the volume of a cylinder:

We have:

and

substitute:
Answer: The area of a base of the cylinder is equal 45 dm².
Answer:
Null hypothesis = H0 : μ = 60
Alternative hypothesis = H1 : μ < 60
Step-by-step explanation:
From the question given :
μ = 60 minutes
xbar = 44.27 minutes
s = 20.4 minutes
The alternative hypothesis is the claim ; which is to hypothesize that the average studying time is 44.27 (which is less than the population average studying time)
The null hypothesis is the initial truth and it is the opposite of the alternative hypothesis.
The hypothesis are :
H0 : μ = 60
H1 : μ < 60
Answer:
In inches it would be 370.36
Step-by-step explanation:
Answer:
The kinds of symmetry the letter H has Point , Line and plane symmetry
Explanation:
Point symmetry states that when every part has a matching part:
the same distance from the central point, but in the opposite direction.
Line of symmetry states that it creates two congruent figures that are mirror images of each other
Plane symmetry states a crystal that divides the crystal into two parts that are mirror images of each other.
Given letter H has line of symmetry because the letter folded in half in any way with the parts matching up.
Also, H has plane and Point Symmetry.
