Answer:
n = 75(2)^d
Step-by-step explanation:
Mathematically, we have the general form of an exponential equation as follows;
y = I(1 + r)^x
where I is the initial value
r is the rate percentage
x is the number of time
From the question, the bacteria population doubles
This mean it increases by 100%
100% = 1
add this to the initial 1, and we have 2
Replace I with the number 75
And d represents the days
so we have;
n = 75(2)^d
In this question there is a small trick that needs to be understood. Basically the ratio in the question is given as a decimal. It can be expressed as a ratio as well.
Ratio of students that voted for winner to the total number of voters = 95:100
The total number of students that voted = 60
Let us assume the common ratio to be = x
then
100x = 60
x = 60/100
= 0.6
Then
The number of votes that the winner got = 95 * 0.6
= 57
So 57 students voted for the winning candidate.
13+14=27
84-27=57
57 runners finished the race.
< = more than
> = less than
So therefore,
D > 5 miles
Hope this helped !
912 divided by 58 would be 15.7241379 so estimated would be 15.7
