Answer:
2 and 4
or 1 and 5
Step-by-step explanation:
well the factors of 20 are
1,2,4,5,10,20
SO 4+2=6 and those are both factors of 20
also 1 and 5
Answer:
im not sure of the answer but hopefully this will help
Step-by-step explanation:
basically the intervals in which its increasing and decreasing depend on the leading coefficient and the vertex
since this is opening up, the intervals will be
the function is increasing (x coord of vertex, infinity)
the function is decreasing (-infinity, x-coord of vertex)
Answer:
a. 
b. 
Step-by-step explanation:
I attach the diagram of the new water tank.
a. In order to find the volume of the tank in cubic feet, we will need to calculate the volume of a cylinder. We know that its base measures 
and its height is 
.
The volume ''V'' of a cylinder is :
Where ''
'' is the diameter of the base and ''
'' is the height of the cylinder.
If we replace all the data in the equation :
We found out that the volume of the tank in cubic feet is
b. We know that 1 cubic foot of water is equal to 7.5 gallons. To find the amount of gallons that the new tank can hold, we need to do an unit conversion.
This equivalence is given to us :
⇒ Using the equivalence ⇒
Finally, the new tank will hold of water.

Which sampling method divides the population up into sections, randomly selects some of those sections, then chooses all the members from the selected sections to study?
Answer: The above mentioned type of sampling is called cluster sampling.
Cluster sampling is a sampling technique in which the entire population of interest is divided into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.
