Step-by-step explanation:

Rational numbers are defined as the numbers that can be expressed as the ratio of two integers(a/b) where b must be a non-zero number. The rational numbers display a terminating characteristic and they also contain repeating, as well as, recurring digits. All the given numbers are rational as they can be written in the form of p/q.

23.429 = It can be written as a fraction. So, it is a rational number.

10 = 10 is a whole number and it can be written in the form of a/b i.e. 10/1. So, it is a rational number.

13 = 13 also can be written in ration form as 13/1. Therefore, it is also a rational number.

151 = It can be written as 151/1. Hence, it is a rational number.

8/7 = It is already mentioned in the form of a/b. So, it is a rational number.

-4.93 = since it is an integer, it will surely be a rational number.

Answer:

the number of days when instructor do the work alone is 8 days

Step-by-step explanation:

Given that

The apprentice can do the work in 24 days

And, the apprentice and  instructor together can do it in 6 days

We need to find out the number of days when instructor do the work alone

So,

[tex]= \frac{1}{6} - \frac{1}{24} \\\\= \frac{4 - 1}{24} \\\\= \frac{3}{24} \\\\= \frac{1}{8} \\\\= 8[/tex]

hence, the number of days when instructor do the work alone is 8 days

Answer:

The Pearson coefficient of skewness is of 0.8284.

Step-by-step explanation:

Pearson skewness:

The skewness of a data set is given by the subtraction of the mean by the median, divided by the standard deviation.

In this question:

The mean is of 87, the median is of 73 and the standard deviation is of 16.9. So

(87-73)/16.9 = 0.8284.

The Pearson coefficient of skewness is of 0.8284.

Answer:

Part A: 3197

Part B: 62

Step-by-step explanation:

Part A: To make this easier just multiply 96 books by 34 rows which is 3264 books, but then since you are taking away 2 books for every row, multiply 2 by the 34 rows which is 68 but since the first row starts at 96 we will take away 1 row from the 68 which is 67. Then subtract 67 from the 3264 books and get 3197 books.

Part B: To make this easier just multiply 17 by 2 since we know for every row, 2 books are taken away and that equals 34 so subtract 34 from 96 and get 62.

Answer:

a(17) = 64

Step-by-step explanation:

you can create an arithmetic sequence formula as follows:

a(n) = a(1) + d(n-1)   where a(1) is the first value and d is the common difference

a(17) = 96 -2(17-1)

a(17) = 96 - 32

a(17) = 64

Answer:

The number of non-positive integral values of [tex]k[/tex] are contained in the following set:

[tex]S_{k} = \{-1, 0\}[/tex]

Step-by-step explanation:

Let be the following second order polynomial:

[tex]x^{2}-(k + 1)\cdot x + (k^{2}+k -8) = 0[/tex], [tex]k \le 0[/tex] (1)

Whose roots can be found by the Quadratic Formula:

[tex]x_{1,2} =\frac{k + 1\pm \sqrt{k^{2}+2\cdot k +1 - 4\cdot k^{2}-4\cdot k +32 }}{2}[/tex]

[tex]x_{1,2} = \frac{k+1}{2} \pm \frac{\sqrt{33-2\cdot k -3\cdot k^{2}}}{2}[/tex]

Based on the statement, we have the following system of inequations:

[tex]\frac{k+1}{2} + \frac{\sqrt{33 - 2\cdot k -3\cdot k^{2}}}{2} > 2[/tex] (2)

[tex]\frac{k+1}{2} - \frac{\sqrt{33 - 2\cdot k -3\cdot k^{2}}}{2} < 2[/tex] (3)

By (2) we have:

[tex]k + 1 + \sqrt{33-2\cdot k -3\cdot k^{2}} > 4[/tex]

[tex]\sqrt{33 -2\cdot k - 3\cdot k^{2}} > 4 - (k + 1)[/tex]

[tex]33 - 2\cdot k -3\cdot k^{2} > [4 - (k+ 1)]^{2}[/tex]

[tex]33 - 2\cdot k -3\cdot k^{2} > 16 -8\cdot (k+1)+(k+1)^{2}[/tex]

[tex]33 - 2\cdot k - 3\cdot k^{2} > 16-8\cdot k -8 + k^{2}+2\cdot k + 1[/tex]

[tex]33 - 2\cdot k -3\cdot k^{2} > 9 -6\cdot k + k^{2}[/tex]

[tex]0 > 4\cdot k^{2}-4\cdot k -24[/tex]

[tex]4\cdot k^{2}-4\cdot k -24< 0[/tex]

[tex]4\cdot (k^{2}-k-6) < 0[/tex]

[tex]k^{2}-k - 6 < 0[/tex]

[tex](k -3)\cdot (k+2) < 0[/tex]

The solution is:

[tex]k \in (-2, 3)[/tex]

Likewise, we get the following expression from (3):

[tex]k^{2}-k - 6 > 0[/tex]

[tex](k -3)\cdot (k + 2) > 0[/tex]

The solution is:

[tex]k \in (-\infty, -2)\,\cup\,(3, +\infty)[/tex]

The number of non-positive integral values of [tex]k[/tex] are contained in the following set:

[tex]S_{k} = \{-1, 0\}[/tex]

Answer:

9/4x^2 - 6x +4

Step-by-step explanation:

( 3/2x-2)^2

(3/2x-2)(3/2x-2)

9/4x^2 - 3x - 3x +4

9/4x^2 - 6x +4

3/2 x 2 = 6/2 = 3

Step-by-step explanation:

( 3/2x-2)² = 9/4 x²- 6x +4

If cos < 0 and cot > 0, then the terminal point is determined by

C. quadrant 3.

In quadrant I the referece angle Ф is Ф.

In quadrant II the referece angle Ф is (π - Ф).

In quadrant III the referece angle Ф is (π + Ф).

In quadrant IV the referece angle Ф is (2π - Ф).

We know, cos is -ve on III and IV quadrants, and cot = 1/tan is +ve on I and III quadrant.

Therefore, The combined condition cos < 0 and cot > 0 satisfies on the II quadrant.

You have an equation and a table with the x value given.

Replace x in the formula with the x value in the table and solve for y.

y = x^2 + 1

y = (-3)^2 + 1 = 9+1 = 10

y = (-2)^2 +1 = 4+1 = 5

y = (-1)^2 +1 = 1+1 = 2

y = (0)^2 + 1 = 0+1 = 1

y = (1)^2 +1 = 1+1 = 2

y = (2)^2 +1 = 4+1 = 5

y = (3)^2 +1 = 9+1 = 10
