3. a Paul is thinking of a number that is greater than 10 and less than 20. What is the probability
that the number is not a prime number? Express your answer as a fraction only.
Answers
The probability that the number is not a prime number is 5/9.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Paul is thinking of a number that is greater than 10 and less than 20.
So, the prime number between 10 and 20 are 11, 13, 17, 19.
So, the probability that the number is not a prime number
= ( 9- 4)/ 9
= 5/9
Hence, the probability that the number is not a prime number is 5/9.

What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
From the triangle DEF and triangle JKL
∠D = ∠J (given)
∠F = ∠L (given)
ED = KJ (given)
∴ Triangle DEF and triangle JKL are congruent by the ASA
ΔDEF≅ΔJKL
Also:
∠F = ∠L (given)
ED = KJ (given)
ΔDEF≅ΔJKL by LA
Thus, the option (C) LA and (D) ASA are correct because two angles and one side are the same.

150 books are divided into 3 stacks. The 1st one has 30 more than the 2nd stack, 2nd stack has twice as many books in the 3rd stack. How many books are there in 3rd stack? (N represents the number of books in the 3rd stack.)
Answers
======================================================
Explanation:
N = number of books in the 3rd stack2N = number of books in the 2nd stack, since there are twice as many books here.2N+30 = add on 30 to the previous amount to get the number of books in the first stackIn other words,
1st stack = 2N+302nd stack = 2N3rd stack = NN is some positive whole number.
Add up all those expressions and set the sum equal to the 150 books total. Solve for N.
(1st stack) + (2nd stack) + (3rd stack) = total
(2N+30) + (2N) + (N) = 150
(2N+2N+N) + 30 = 150
5N + 30 = 150
5N = 150-30
5N = 120
N = 120/5
N = 24 which is the number of books in the 3rd stack
2N = 2*24 = 48 is the number of books in the 2nd stack.
2N+30 = 2*24+30 = 48+30 = 78 books in the 1st stack
Check:
1st+2nd+3rd = 78+48+24 = 150
The answer is confirmed.

Srekar needs to increase the length, width, and height of the prism below by 2 inches. The original prism has a length of 3 inches, a width of 2 inches, and a height of 1 inch.
A prism has a length of 3, height of 1, and width of 2.
Which statements about the new prism are true? Select three correct answers.
The new prism will have a length of 5 because 3 + 2 = 5.
The new prism will have a width of 4 because 2 + 2 = 4.
The new prism will have a height of 2 because 1 times 2 = 2.
The volume will increase by 6 because 2 times 3 = 6 and each of the 3 dimensions is increased by 2.
Srekar could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side.
The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each.
Answers
The statement first, statement second, and statement sixth are true.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have:
The original prism has a length of 3 inches, a width of 2 inches, and a height of 1 inches.
The new length = 3+2 = 5 inches
The new width = 2+2 = 4 inches
The new height = 1+2 = 3 inches
The volume of the old prism = 3×2×1 = 6 cubic inches
The volume of the new prism = 5×4×3 = 60 cubic inches
Srekar, could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side is false becasue:
Volume = 3×2×(1+6) = 42 cubic inches
The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each is true.
Thus, the statement first, statement second, and statement sixth are true.

Determine the truth value of each statement based on the expression.

Answers
By analyzing the polynomial we have the following conclusions about the five propositions:
1) True
2) True
3) False
4) False
5) True
How to infer characteristics of a polynomial
In this question we have a second order polynomial with two variables (x, y) and we need to determine the truth value of each proposition by applying concepts related to polynomials.:
1) There are four terms - A term is an additive component of the polynomial. Thus, the polynomial has four terms. (True)
2) 6 · x² and 3 · x are like terms - Two components are like terms if they have the same variable. Thus, 6 · x² and 3 · x are like terms. (True)
3) The coefficient on y is 14 - A coefficient is a constant that accompanies a variable. The constant of y is -14. (False)
4) Simplified, the expression is 6 · x² + 5 · x - 14 · y - The simplification of the polynomial is done by applying algebraic properties. The simplified form is 6 · x² + x - 14 · y. (False)
5) The commutative property allows the expression to be written as 6 · x² - 14 · y + 3 · x - 2 · x - Commutative property indicates that the order of components of the polynomial can be changed without changing the result of the entire polynomial. (True)
Remark
The statement is incomplete and incorrectly formatted. Correct statement is shown below:
Determine the truth value of each statement based on the expression 6 · x² - 2 · x - 14 · y + 3 · x.
1) There are four terms.
2) 6 · x² and 3 · x are like terms.
3) The coefficient on y is 14.
4) Simplified, the expression is 6 · x² + 5 · x - 14 · y.
5) The commutative property allows the expression to be written as 6 · x² - 14 · y + 3 · x - 2 · x.

The percentage of pies sold that were apples or cherry is 52%
How to determine the percentage of apples or cherry?The given parameters are:
Apple = 32Pumpkin = 33Cherry = 20Chocolate = 15The total number of pies is:
Total = 32 + 33 + 20 + 15
Evaluate
Total = 100
The percentage of apples or cherry is calculated as:
Percentage = (Apple + Cherry)/Total
So, we have:
Percentage = (32 + 20)/100
Evaluate the quotient
Percentage = 0.52
