There will be 1,215,450 different random samples of four accounts are possible.

There are two methods to calculate the number of ways a certain event can happen. Both are used in different circumstances, such as, when the order of arrangement does not matter we use the combination and when the order matters we use permutation.

Given,

Population size, N = 75

Sample size, n = 4

We have selected a random sample of 4 accounts in order to learn about the population because these accounts can not be repeated and can be in any order, so we will use combination without repetition. According to this, the number of ways by which n subjects can be chosen from N subjects are given by,

[tex]\frac{N}{n}[/tex] = [tex]\frac{N!}{n!(N-n)!}[/tex]

Therefore, required number of ways are,

= 75!/4!(75-4)!

= 75!/4!*71!

= 75*74*73*72*/4*3*2

=  1,215,450

Hence, There will be 1,215,450 different random samples of four accounts are possible.

The probability of selecting an even number or a number less than 5 is therefore

The correct answer is option A

EXPLANATION

The three numbers are 36, 46 and 56. This is because the only three numbers that have 6 ones and wich are included between 30 and 60 are 36, 46 and 56, no other number can comply that condition.

The slope of the line graph is -1.

The slope of a line is the change in the dependent variable with respect to the change in the independent variable.

The slope is rise over run.

Therefore,

slope = y₂ - y₁ / x₂ - x₁

Using (3, -3) and (-2, 2)

Therefore,

x₁ = 3

x₂ = - 2

y₁ = -3

y₂ = 2

Hence,

slope  = 2 + 3 / -2 - 3

slope = 5 / -5

Therefore,

slope = - 1

Answer

The statement is always true.

Explanation

Since equivalent ratios reduce to essentially the same fundamental ratios, if the numerator of one of the ratios is greater than its denominator, then the numerator of each of the equivalent ratios must be greater than each of their corresponding denominators too.

So, this statement is always true!

Hope this Helps!!!

In order to find the value of a composition of functions at x = a, (f º g)(a), we first find the value of g(a), then find the value of f(x) at x = g(a).

(f º g)(a) = f(g(a))

In this problem, the values of f(x) and g(x) are shown in the table, for integer values of x from 0 to 9.

So, we have:

1. (f º g)(8) = f(g(8))

From the table, we see that

g(8) = 4 (value of g(x) in the line corresponding to x = 8)

Then:

f(g(8)) = f(4) = 4 (value of f(x) in the line corresponding to x = 4)

Thus:

2. g(f(3))

f(3) = 8

g(8) = 4

Thus:

3. f(f(1))

f(1) = 6

f(6) = 2

Thus:

4. (g º g)(6) = g(g(6))

g(6) = 7

g(7) = 3

Thus:

Given the vector represented by:

You know that:

By definition, the Component Form of a vector is:

In this case, you only need to multiply the coordinates of "a" by 8, in order to find the Component Form of:

Therefore, you get:

Hence, the answer is:

The slope of a line shows the relation between a unitary increment in the x-variable and the corresponding change in the y-variable.

In this case, the x-variable represents the amount of fertilizer, in grams, and the y-variable represents the height of the seedings, in cm.

Then, the slope of 0.8 means that when the x-variable increases in 1 unit, the y-variable increases 0.8 units. Or more specifically, for each additional gram of fertilizer used, the height of the seedings increases by about 0.8 cm on average.

Given the expression :

The answer will be as follows, add the decimal point and two zeros

See the following picture:

1) Let's multiply the second equation by -2, to eliminate x

2x -3y=-11

x+3y = 8

2) Now let's add both equations

2x -3y=-11

-2x-6y = -16

--------------------

-9y = -27

3) Divide both by -9

y=3

4) Plug y=3 into the simpler original equation, to make calculations easier:

x +3y=8

x+3(3) =8

x +9 =8 Subtract 9 from both sides

x = 8-9

x=-1

So, after multiplying it we add both equations to eliminate one variable either x or y.

Answer:

$8.4

Explanation:

To find how much money you should leave for a tip, we need to find how much is 20% of $42. So, to calculate this, we need to multiply 42 by 20 and then divide by 100, so:

$42 x 20% = 42 x 20 / 100 = 840 / 100 = 8.4

Therefore, the answer is $8.4

• Small cones (s): $2

• Large cones (L): $3.50

• Total sold (T): $163

• The number of L sold was 12 more than the number of ,s.

Procedure

We have to build a system of equations based on the information given.

• Equation 1:, she sold $163 of small and large cones

• Equation 2: ,the number of L sold was 12 more than the number of ,s.

As we have L isolated in the second equation, it is convenient to use this expression in the first equation to have it in terms of one variable:

Simplifying the parenthesis we get:

As we have two terms with an s we can group in each side of the equation the common terms and simplify them as follows:

Now that we have s, we just have to replace this value in equation 2:

So to make equal groups just create the number of groups (divisor, in this case: 4) and insert into that the number of the quotient( in this case: 7)

1) Let's make equal groups for that division since 7 added 4 times is equal to 28:

2) Since 7 x 4 is the same as adding 7 four times, we have above four groups with seven balls that added up yields 28, in each group we have 7 balls.

3) So to make equal groups just create the number of groups (divisor) and insert into that the number of the quotient. Note that this is valid just for exact divisions.

Answer:

x=6 ft

Explanation:

The given polygon is a trapezium in which:

• The parallel sides are a=16 ft and b=(16+2x) ft

• The height, h = 8 ft

• Area = 176 sq.ft.

The area of a trapezium is calculated using the formula:

Substitute all the known values:

Divide both sides by 4.

Subtract 32 from both sides:

Divide both sides by 2.

The value of x in the drawing is 6 feet.

Answer:

X=6

Step-by-step explanation:

First multiply 8 by 16 to get 128. Then subtract that from 176 to get 48. Then divide by to because there are two triangles to get 24, so each triangle is 24 square feet. Find a number that multiplied by 8 equals 48 (this will be x). The reason that I did this is because of the formula for area of a triangle (B*H/2=A). After you divide by 48 by 2 you will get 24. The number that was multiplied by 8 is x (x=6).
