Using the Fundamental Counting Theorem, it is found that:

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

For the 2 letters(26 outcomes each), and 3 numbers(10 outcomes each), we have that the parameters are:

[tex]n_1 = 26, n_2 = 26, n_3 = 10, n_4 = 10, n_5 = 10[/tex]

Hence the number of catalog numbers is:

[tex]N = 26^2 \times 10^3 = 676000[/tex]

The ID number is divisible by 5 if the last digit is either 5 or 0, hence [tex]n_5 = 0[/tex] and the probability is:

[tex]p = \frac{26^2 \times 10^2 \times 2}{26^2 \times 10^3} = 0.2[/tex]

There is a 0.2 = 20% probability that the ID number is divisible by 5.

Answer:

slope: 14

y intercept: (0,9)

Step-by-step explanation:

in the form y = mx + b, the slope is m: 14

to solve for the y intercept, we set x as 0: 14 * 0 + 9 = y interecept is 9.

A) The collection of positive integers whose sum is 100 are: 23, 17, 6, 54, 0.

B) Another collection of positive integers whose sum is 100 are: 13, 27, 4, 56, 0.

C) Due to the fact that the units can be commuted, their sum is always equal to 20.

D) The smallest possible value is 0 and the largest is 57.

A) The formation of a collection of positive integers can be done by trial and error. For example, only using the digits {0, 1, 2, 3, 4, 5, 6, 7}.

For example, we can have;

23 + 17 + 6 + 54 + 0 = 100

Where the numbers used are: 23, 17, 6, 54, 0.

B) Another example is;

13 + 27 + 4 + 56 + 0 = 100

C) If we add the units digits of these 5 numbers, we get:

3 + 7 + 6 + 4 + 0 = 20

Now, if we compute the units digits between the different numbers, to get for example: 27, 13, 6, 54, 0

The sum is still equal to 100, and the units digits are the same ones, so we still have that the sum of the units digits is equal to 20.

d) The smallest integer that we use is 0.

For the largest we just commute the tens and units digits so we make the larger integer possible, which is:57.

The percentage increase China's population from 1970 to 1995 is: 56.25%.

Percentage increase = (Final Value - Original Value)/Original value × 100.

Given the following:

Original value = 0.8 billion

Final Value = 1.25 billion

Final Value - Original Value = 1.25 - 0.8

Final Value - Original Value = 0.45

Percentage increase = 0.45/0.8 × 100 = 56.25%.

There are 28 elements in the sample space and the probability of a green card is 9/28

The given parameters are:

Red = 7

Green = 9

Blue = 12

The elements in the sample space is:

Elements =7 + 9 + 12

Evaluate

Elements = 28

Hence, there are 28 elements in the sample space

This is calculated as

P =Green/Elements

So, we have:

Step-by-step explanation:

so, what do we need to do ?

just solve these equations and find Sam's age (and Harry's) ?

x = 3y

x = 10 + 2y

so, we simply use the first equation in the second :

3y = 10 + 2y

y = 10

x = 3y = 3×10 = 30

Sam is currently 30 years old, Harry is 10.

The regression equation is (d) log(y) = 0.064x + 1.706

The table of values is given as:

x   2   3   4   5   6

y   73  77  85  101  133

Calculate the logarithm of the y values.

So, we have:

x          2   3   4   5   6

log(y)   1.86  1.89  1.93  2  2.12

Next, we enter the above values in a regression calculator.

From the calculator, we have the following summary:

The regression equation is then represented as:

log(y) = bx + a

Where:

b = SP/SSX = 0.64/10 = 0.064

a = MY - bMX = 1.96 - (0.064*4) = 1.706

So, we have:
