We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.

Upon substituting initial value
and
in above formula, we will get:





Therefore, there will be approximately 3300 cells at the end of 12 hours.
Answer:
Im not entirely sure this is right but
0 = tan^-1(20 ÷ 25)
0 ≈ 38.65°
hope i helped lol
A normally distributed data set has a mean of 0 and a standard deviation of 2. The closest to the percent of values between -4.0 and 2.0 would be 84%.
<h3>What is the empirical rule?</h3>
According to the empirical rule, also known as the 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95%, and 99.7% of the values lies within one, two, or three standard deviations of the mean of the distribution.

A normally distributed data set has a mean of 0 and a standard deviation of 2.
