Answer:
(A) The mean will decrease more than the median.
Step-by-step explanation:
$500 is much more than the mean of $93.80, so removing it from the data set will decrease the mean significantly. The median of $75.80 will move to the next smaller number, so the change will be small or even none.
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m
or
-7m - 8 = m - 4
or
-8 - 7m = -4 + m
Answer
2) -7m - 8 = m - 4
4) m - 4 = -7m - 8
5) -8 - 7m = -4 + m

Answer: it will take 18.2 years
Step-by-step explanation:
We would apply the formula,
y = ab^t
Where
a represents the initial amount of bacteria.
t represents the doubling.
From the information given
a = 10
t = 1 hour
Since after 1 hour, the amount of bacteria multiplies by 2, then
y = 2 × 10 = 20
Therefore
20 = 10 × b^1
Dividing through by 10, it becomes
2 = b
The equation becomes
y = 10(2)^t
For 3,000,000 bacteria, then
3000000 = 10(2)^t
3000000/10 = (2)^t
300000 = (2)^t
Taking log of both sides, it becomes
Log 300000 = tlog2
5.477 = 0.301t
t = 5.477/0.301
t = 18.2 years
I believe this would be your answer > N = 5
