Answer:
Initial population = 313
Population after 5 hours = 
Step-by-step explanation:
Let initial population = 
It is given that population gets doubled every 10 minutes.
Population after 10 minutes = 
Population after 20 minutes = 
:
:
Population after 80 minutes = 
and it is given as 80000.
So, initial population is 312.5 = ~313
To find, population after 5 hours i.e. 5 
60 = 300 minutes
Population after 300 minutes =
So, the <em>answers </em>are:
Initial population = 313
Population after 5 hours =
In question in and 2 it is just asking for X and 3 and 4 is just the order might be wrong depending on what your doing in math but it should be right.
Answer:
Option 4
Step-by-step explanation:
Group B, because seven children have a forearm length longer than 10 inches.
Additional verification :
Finding average forearm length of Group A :
- 9(3) + 10(5) + 11(2) / 10
- 27 + 50 + 22 / 10
- 99/10
- 9.9
Finding average forearm length of Group B :
- 10(3) + 11(4) + 12(3) / 10
- 30 + 44 + 36 / 10
- 100/10
- 10
Group B clearly has the longer forearm length.
Answer:
(D) 14
Step-by-step explanation:
5x (14-x) = 0
5(14)*(14-14)=0
70*0=0
