Answer:
They are only equal on day 0, both having 10 population.
Step-by-step explanation:
Given the bacteria on the counter is initially measured at 5 and doubles every 3 days we can generate the following geometric equation:

Given the bacteria on the stove is measured at 10 and doubles every 4 days we can create another equation:

To find how many days it will take for the bacteria population to equal the same lets set both equations equal to eachother:

Divide both sides by 10

Since both exponents have the same base we can set the exponents equal to eachother and solve for x:

Multiply both sides by 3 to isolate x on the left side

Multiply both sides by 4 to remove fraction

Subtract 3x to isolate x on the left side

Plug x into one of our original equations

Solve

The answer to the first one is a
Answer:
23
Step-by-step explanation:
The absolute value of any number is just the positive version of that number. For example the absolute value of -12 is 12.

Answer: 83
Step-by-step explanation:
The confidence interval for population mean is given by :-

Given : The student obtained the following 95% confidence interval (in grams) for the population mean, (862,1028).
Here,
Lower limit of the confidence interval :
(1)
Upper limit of the confidence interval :
(2)
Subtracting (1) from (2) , we get

Hence, the margin of error = 83
