The count of bacteria in a culture is 10 and doubles every 20 minutes. Find the population size after 11 hours. Can someone expl
1 answer:
Since you asked how to solve this, I will put the answer at the bottom.
You might not think the same way as I but I think in steps.
<h3>(1) Calculate how many times the bacteria divide in eleven hours</h3>The bacteria divide every 20 minutes, and will therefore divide three times every hour, 60/20 = 3.
If the bacteria grow for eleven hours, each bacterium will divide 3 times per hour × 11 hours = 33 times.
<h3>(2) Add the orginial size of bacteria into the equation</h3>(This part is edited)
(orginial size)*2^number of divisions
10*
=85899345920

Step-by-step explanation:
We attached a table below,
We attached a table below,
Therefore ,
correlation coefficient
We calculate the least squares equation.
Now , calculate intercept coefficient.
Therefore, the regression equation is,
Find the volume of cerebral brey matter for a child whose head circumference Z score at age 12 months was 1.8
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).
<h3>What is a t-distribution confidence interval?</h3>The confidence interval is:
In which:
is the sample mean.
- t is the critical value.
- n is the sample size.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a <u>two-tailed 95% confidence interval</u>, with 25 - 1 = <em>24 df</em>, is t = 2.0639.
The other parameters are given by:
.
Hence, the bounds of the interval are given as follows:
The 95% confidence interval is (29.6, 44.4).
