Area of a square = pie r^2.
Radius = sqrt 484 = 22.
Diameter = 2 r = 2 x 22 = 44.
Hope this helps!
Answer:
I think it's the amount of money Mary earns for 10 hours worked.
Step-by-step explanation:
The answer is 1,695.6 in³.
The volume of the empty space is the difference of the bigger cylinder and the smaller cylinder: V = V1 - V2
The volume of the bigger cylinder is:
V1 = π r² h
r = 10 in
h = 15 in
π = 3.14
V1 = 3.14 * 10² * 15 = 4,710 in³
The volume of the smaller cylinder is:
V2 = π r² h
r = 8 in
h = 15 in
π = 3.14
V2 = 3.14 * 8² * 15 = 3,014.4 in³
The volume of the empty space is:
V = V1 - V2 = 4,710 in³ - 3,014.4 in³ = 1,695.6 in³
Answer: 
Step-by-step explanation:
- A null hypothesis is a hypothesis where a researcher generally try to disprove, it says that there is no statistically significant relationship between the two variables .
- An alternative hypothesis says that there is a statistical significance between two variables.
Claim 1. : Mean age of online dating service users is 40 years.
i.e. 
, since it has equals sign so we take this as null hypothesis.
Claim 2. : Mean age of online dating service users is not 40 years.
⇒ Null Hypothesis :
Alternative hypothesis :
Answer:
3.66666666667
Step-by-step explanation:
If you multiply the number of batches he makes and the amount of grape juice he needs for every quart, you get and answer of 3.66666666667.
1/3 * 11= 3.66666666667
If you need to round the answer it would be 3.67
