There are (A) 2.7 bacterias initially.

<h3>What is a function?</h3>

A function is an expression that establishes the relationship between the dependent and independent variables.
A function from a set X to a set Y allocates exactly one element of Y to each element of X.
The set X is known as the function's domain, while the set Y is known as the function's codomain.
Originally, functions were the idealization of how a variable quantity depends on another quantity.

To find the number of bacteria:

The graph shows that the function follows an exponential curve, and the starting point is at ( 0,2.7 ).
The starting number of bacteria is then 2.7.

Therefore, there are (A) 2.7 bacterias initially.

What does absolute value mean?

Lynna [10]

Absolute value is the magnitude of a number without regard to its sign. for example, the absolute value of 5 is 5, and the absolute value of -5 is also 5!

Suppose in the University of Manitoba, 40% of the students live in apartments. If 600 students are randomly selected, then the a

Answer:

$P(200\leq X\leq 400)=P(\frac{200-240}{12}\leq \frac{X-\mu}{\sigma}\leq \frac{400-240}{12})=P(-3.33\leq Z \leq 13.33)$

$=P(Z$

So then the correct answer would be:

B) .9996

Step-by-step explanation:

The exact way to solve this problem is using the binomial distribution, assuming that our random variable of interest is "number of students living in apartments" represented by X and $X \sim Bin(n=600, p =0.4)$

And we want this probability:

$P(200 \leq X \leq 400) [tex]In order to find this probability we can use the foloowing excel code:"=BINOM.DIST(400,600,0.4,TRUE)-BINOM.DIST(199,600,0.4,TRUE)"And we got:[tex] P(200 \leq X \leq 400) =0.999675[tex]But for this case the problem says that we need to approximate, so then we can use the normal approximation to the normal distribution. We need to check the conditions in order to use the normal approximation.
