it's 2 I used my calculator
Answer:
The median is 10 and the mean is 10.2
Step-by-step explanation:
Median: the middle number -> 6,8,10,11,16
Mean:
6 + 8 + 10 + 11 + 16 = 51
51/5 = 10.2
For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
As per the given information;
Bacteria triples every month.
Originally, there were 4 bacterial cells.
We are suppose to find how many there will be after 15 months.
Hence we can say , the number of bacteria after n month can be given using the exponential growth function

So number of bacteria after 15 month will be

Answer (apply the FOIL method)
X^2+8x+15
