Sergio [31]

Answer:

largest number os students = 73

smallest number of students is 16

Step-by-step explanation:

Distribution of student over the period of 13 year is given in the following table

first column represent the stem which are on tens digit while column 2 represent the leaf which are on one digit.

1 6 9

2 4 4 9

3 3 4 7

4 0 2 6 9

5

6

7 3

8

9

hence the graduate student number is calculated as

16, 19, 24,24,29, 33, 34,37,40,42,46,49,73.

hence from the obtained data largest and smallest number of students over a period of 13 year can be calculate

largest number os students = 73

smallest number of students is 16

The population of algae in an

Westkost [7]

Given:

Initial population = 100 algae

Growth rate = 30% per day.

Time = 5 days

To find:

The future amount of population.

Solution:

The exponential growth model is

$y=a(1+r)^t$

where, a is the initial value, r is the rate of interest in percent and t is time period.

Substituting the given values, we get

$y=100(1+\dfrac{30}{100})^5$

$y=100(1+0.30)^5$

Now, solve this.

$y=100(1.30)^5$

$y=100(3.71293)$

$y=371.293$

Therefore, the future value is 371.293 algae.

never [62]

Option A:

{3, 4, 5, 6}

Solution:

In the given table X column have 3, 4, 5, 6 and Y column have 4, 4, 2, 5.

The domain is the set of all values for which the function is defined.

The domain of the function is set of all X values.

Option A: {3, 4, 5, 6}

Set of all X values {3, 4, 5, 6}.

It is correct.

Option B: (3, 4), (4, 4), (5, 2), (6, 5)

Here, the given values are ordered pairs of domain and co-domain.

It is not correct.

Option C: (3, 4)

Here, (3, 4) is a ordered pair of domain and co-domain.

It is not correct.

Option D: {2, 4, 5}

Here, {2, 4, 5} are values of co-domain.

It is not correct.

Hence {3, 4, 5, 6} is the domain of the function.
