Eight more than the quotient of a number and 7 is equal to 3.
Answers
The " Eight further than the Quotient of a number and 7 is equal to 3," and the result to the equation is x = -35.
The equation 8( x/ 7) = 3 represents the judgment " Eight further than the Quotient of a number and 7 is equal to 3," and the result to the equation is x = -35.
" Eight further than" implies addition, so we've 8 " The quotient of a number and 7" means dividing a number by 7, so we've x/ 7 " is equal to" means that the expression on the left side is equal to the expression on the right side, so we've = " 3" is the value to which the expression on the left side is equal, so we've 3 Putting it all together the judgment " Eight further than the quotient of a number and 7 is equal to 3" can be restated into the equation ( x/ 7) = 3
In this equation, x represents the number we're trying to find. To break for x, we can manipulate the equation using algebraic operations to insulate x on one side of the equation. By abating 8 from both sides of the equation, we get ( x/ 7)- 8 = 3- 8 Simplifying, we have x/ 7 = -5
To insulate x, we can multiply both sides of the equation by 7 *( x/ 7) = -5 * 7 This gives us x = -35 thus, the equation 8( x/ 7) = 3 represents the judgment " Eight further than the quotient of a number and 7 is equal to 3," and the result to the equation is x = -35.

which range function will create a list with all odd numbers between 5 and 77?
Answers
A range function that will create a list with all odd numbers between 5 and 77 is range(5, 78, 2).
The range function is a built-in function in Python which returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and stops before a specified number. In other words, the range function returns a sequence of numbers between the given range. In order to create a list of all odd numbers, the start and end of the range is specified first, and the condition is specified next. As the difference between two consecutive odd numbers is two, it is the defined increment. Hence, the range will give a lists as 5, 7, 9, 11,…..,77.

Nikhil and Mae work at the same company. Nikhil has been at the company 4 time+s as long as Mae. Nikhil's time at the company is 8 more than 2 times Mae's time. The following system of equations models the scenario: x = 4y x = 8 + 2y How many years has each person been employed by the company? Nikhil has been with the company for 16 years, while Mae has been there for 4 years. Nikhil has been with the company for 24 years, while Mae has been there for 6 years. Nikhil has been with the company for 20 years, while Mae has been there for 5 years. Nikhil has been with the company for 12 years, while Mae has been there for 3 years
Answers
Applying the system of equations given, we can conclude that: a. Nikhil has been with the company for 16 years, while Mae has been there for 4 years.
How to Apply a System of Equations?To solve the system of equations, let's substitute the value of x from the first equation into the second equation:
x = 4y
8 + 2y = 4y
Simplifying the equation, we get:
8 = 2y
Dividing both sides by 2:
4 = y
Now, substitute the value of y back into the first equation to find x:
x = 4y
x = 4(4)
x = 16
Therefore, Nikhil has been employed by the company for 16 years, and Mae has been employed for 4 years.
The correct answer is option a. Nikhil has been with the company for 16 years, while Mae has been there for 4 years.

Given the function
\(\begin{gathered} f(x)=-x+5 \\ g(x)=x^2-3x+2 \end{gathered}\)We can find the graph of the function below.
Explanation
First, we will pick points for the x -coordinates. The set of suitable values for f(x) will be in the range
\(-3\leq x\leq3\)The set of suitable values for g(x) will be in the range
\(-3\leqslant x\leqslant5\)Part A: Table of values for f(x) i.e y
\(\begin{gathered} When\text{ x =-3} \\ y=-x+5=-(-3)+5=8 \\ when\text{ x=-2} \\ y=-(-2)+5=7 \\ when\text{ x =-1} \\ y=-(-1)+5=6 \\ when\text{ x =0} \\ y=(0)+5=5 \\ when\text{ x =1} \\ y=-1+5=4 \\ when\text{ x=2} \\ y=-2+5=3 \\ when\text{ x= 3} \\ y=-3+5=2 \end{gathered}\)Therefore the table of values for f(x) becomes
Part B: Table of values for g(x) i.e y
\(\begin{gathered} when\text{ x=-3} \\ y=x^2-3x+2=(-3)^2-3(-3)+2=20 \\ When\text{ x = -2} \\ y=(-2)^2-3(-2)+2=12 \\ When\text{ x= -1} \\ y=(-1)^2-3(-1)+2=6 \\ when\text{ x =0} \\ y=(-0)^2-3(-0)+2=2 \\ When\text{ x= 1} \\ y=(1)^2-3(1)+2=0 \\ when\text{ x= 2} \\ y=(2)^2-3(2)+2=0 \\ when\text{ x= 3} \\ y=(3)^2-3(3)+2=2 \\ When\text{ x =4} \\ y=(4)^2-3(4)+2=6 \\ when\text{ x=5} \\ y=(5)^2-3(5)+2=12 \\ \end{gathered}\)The table of values

Answer: 4.9
Step-by-step explanation:
The height of the bookshelf is 4.3 feet and the height of the desk is 2.45 feet.
What is the system of equations?Simultaneous equations are any one or more equations that can have the same number of unknowns and be solved concurrently. The system of equations is a simultaneous equation.
Given:
A bookshelf sits on top of a large desk.
Together, their height is 6.75 feet.
The difference between their heights is 1.85 feet.
Let the height of the bookshelf = x and the height of the desk = y.
x + y = 6.75 {equation 1}
x - y = 1.85 {equation 2}
Add both equations,
we get,
2x = 6.75 + 1.85
2x = 8.6
x = 4.3
And from equation 2,
y = 2.45
Therefore, the solution is x =4.3 and y = 2.45.

show that a) cos3∅=cos²∅-3cos∅sin²∅
Answers
The correct proof of the equation is cos3θ =cos(2θ + θ) = cos²θ - 3cosθsin²θ (Proved)
Solving trigonometry identity
Given the trigonometry identity below:
cos3∅=cos²∅-3cos∅sin²∅
We are to prove that both sides of the equation are equal.
cos 3θ = cos(2θ + θ)
Using the double angle formula for cosine, we can expand the first term:
cos(2θ + θ) = cos2θ cos θ - sin2θ sinθ
Since cos2θ = cos²θ - sin²θ
cos(2θ + θ) = cos²θ - sin²θ - 2cosθsinθsinθ
cos(2θ + θ) = cos²θ - sin²θ - 2cosθsin²θ
On simplifying, we can see that;
cos3θ =cos(2θ + θ) = cos²θ - 3cosθsin²θ (Proved)

a 5-card hand is (randomly) drawn from a standard 52 card deck. (a) what is the probability that the hand contains all clubs? (b) what is the probability that the hand contains three aces and two kings? (c) what is the probability that the hand contains 4 cards of the same suit, and 1 of another suit?
Answers
(a) The probability of drawing the first club is 13/52 (since there are 13 clubs in the deck out of 52 total cards).
After that, there are 12 clubs left out of 51 cards, so the probability of drawing a second club is 12/51.
Similarly, the probability of drawing a third club is 11/50, the probability of drawing a fourth club is 10/49, and the probability of drawing a fifth club is 9/48. Therefore, the probability of drawing a 5-card hand with all clubs is: (13/52) x (12/51) x (11/50) x (10/49) x (9/48) = 0.000495% (rounded to six decimal places)
(b) The number of ways to choose 3 aces out of 4 is (4 choose 3) = 4, and the number of ways to choose 2 kings out of 4 is also (4 choose 2) = 6. The remaining card can be any of the 44 non-aces and non-kings in the deck. Therefore, the number of 5-card hands that contain 3 aces and 2 kings is: 4 x 6 x 44 = 1056
The total number of 5-card hands is (52 choose 5) = 2598960. Therefore, the probability of drawing a 5-card hand with 3 aces and 2 kings is: 1056/2598960 = 0.04074% (rounded to five decimal places)
(c) There are four suits in a standard deck, so there are four ways to choose the suit that will have 4 cards in the hand. The number of ways to choose 4 cards from a single suit is (13 choose 4) = 715. The remaining card can be any of the 39 cards in the other three suits. Therefore, the number of 5-card hands that contain 4 cards of the same suit and 1 card of another suit is: 4 x 715 x 39 = 111540
The total number of 5-card hands is (52 choose 5) = 2598960. Therefore, the probability of drawing a 5-card hand with 4 cards of the same suit and 1 card of another suit is:
111540/2598960 = 4.29% (rounded to two decimal places)
