Answer:
B has a smaller initial population of 500
Step-by-step explanation:
Given
See attachment for complete question
Required
The bacteria with the smaller initial population
The initial population is at x = 0
For bacteria A;
when 
For bacteria B, we have:
Substitute 0 for x
So; when x = 0
and
Because; 500 < 600
We can conclude that B has a smaller initial population of 500
If the student got 123 marks and failed by 39, your first step would be to add the two together, getting 162. This is the amount of marks needed to pass the test.
You would then divide 162 by .36 (.36 is equivalent to 36%). This would result in a maximum of 450 marks.
The maximum marks on this test are 450 marks.
Answer:
Let l be length and w be width.
First equation:
l = 2w-4
Second equation:
perimeter = 40 units
Perimeter of a rectangle: 2(l+w)
2(2w-4+w)=40
2(3w-4)=40
6w-8=40
6w=40+8
6w=48
w=48/6
w=8
Therefore the width=8;
length= 2w-4 = 2(8)-4 = 16-4 = 12
perimeter = 40 units
First part of question states;
A poll conducted in 2013 found that the proportion of of U.S. adult Twitter users who get at least some news on Twitter was 0.52 The standard error for this estimate was 0.024, and a normal distribution may be used to model the sample proportion.
Answer:
<u>True</u>
<u>Step-by-step explanation:</u>
From the statement above and after constructing the 99% confidence interval for the proportion of U.S. adult Twitter users we can infer that the 95% confidence upper and lower bounds are 0.52 and 0.79, which means that there's a 99% confident that the true percentage of U.S. adults Twitter users who get some news through Twitter is between the upper and lower bounds of the confidence interval.
