Answer:
13, 4, and 4
Step-by-step explanation:
The absolute value of a difference measures the discrepancy between the two numbers inside. The 13 represents the ideal amount of biscuits and x represents the actual number of biscuits in the package. So the difference between the actual and the ideal is 4 (whether it's 4 more of 4 less than 13).
The situation described doesn't actually match the wording, because this says there'll either be 9 or 17 biscuits in the package, due to the "=". If you wanted to have "as many as," then this should be "≤", allowing for 4 or fewer in either direction.

The quotient of a number and -4 is -9
Answer:36
Step-by-step explanation:36÷ -4 = -9
The answer would be 36 which is 36÷ -4 = -9 after applying the arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The quotient of a number and -4 is -9
Mathematically we can write:
x ÷ -4 = -9
x/(-4) = -9
x = 36
OR
36 ÷ -4 = -9
Thus, the answer would be 36 which is 36÷ -4 = -9 after applying the arithmetic operation.

A rectangular prism is made up of 320 unit cubes. The prism is 8 unit cubes wide.
Which could be the other dimensions of the rectangular prism? Choose all the possible dimensions.
A. 4 unit cubes long
10 unit cubes high
B. 5 unit cubes long
8 unit cubes high
C. 8 unit cubes long
5 unit cubes high
D. 8 unit cubes long
8 unit cubes high
E. 10 unit cubes long
4 unit cubes high
F. 20 unit cubes long
2 unit cubes high
G. 20 unit cubes long
20 unit cubes high
H. 25 unit cubes long
15 unit cubes high
Answer:
A, B, C, E, F.
Step-by-step explanation:
320 / 8 = 40
So the length times the height of the prism will be 40.
So the possible dimensions are
A ( 4 * 10).
B.
C.
E.
F
The option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
We have volume of rectangular prism = 320 cubic unit
Width of the rectangular prism = 8 unit
320 = l×w×h
320 = 8l×h
l×h = 40
So the multiplication of the length and height should be 40
A. 4 unit cubes long and 10 unit cubes high:
l×h = 4×10 = 40
B. 5 unit cubes long and 8 unit cubes high:
l×h = 5×8 = 40
C. 8 unit cubes long and 5 unit cubes high:
l×h = 8×5 = 40
D. 8 unit cubes long and 8 unit cubes high:
l×h = 8×8 = 64
E. 10 unit cubes long and 4 unit cubes high:
l×h = 10×4 = 40
F. 20 unit cubes long and 2 unit cubes high:
l×h = 20×2 = 40
G. 20 unit cubes long and 20 unit cubes high:
l×h = 20×20 = 400
H. 25 unit cubes long and 15 unit cubes high:
l×h = 25×15 = 375
Thus, the option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.

If a painter paints 3 rooms in 1/2 day, what would be a reasonable estimate, how many rooms would painter paint in working 5 days? What is painters rate of painting in rooms painted per day? *
Answer:
Rate per day: 6 rooms
estimate: 6*5 = 30 rooms
7.21. For a group of 100 people, compute a. the expected number of days of the year that are birthdays of exactly 3 people; b. the expected number of distinct birthdays.
The expected number of a dataset is the mean of the dataset
The expected number of selection is: [tex]\mathbf{E(x) =365\times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{97}}[/tex]The expected number of distinct birthdays is: [tex]\mathbf{E(x) = 365\times (1 - (\frac{364}{365})^{100})}[/tex]The given parameters are:
[tex]\mathbf{n = 100}[/tex] --- sample size
[tex]\mathbf{r = 3}[/tex] --- selection of 3 people
(a) The expected number of birthdays
The probability of a having a birthday on a certain day is:
[tex]\mathbf{p = \frac{1}{365}}[/tex]
The probability of not having a birthday on the day is:
[tex]\mathbf{q = \frac{364}{365}}[/tex]
For a selection of 3 people in 100, the expected number of selection is:
[tex]\mathbf{E(x) =Days \times ^{100}C_3 \times p^3 \times q^{100 - 3}}[/tex]
So, we have:
[tex]\mathbf{E(x) = Days \times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{100 - 3}}[/tex]
Rewrite as:
[tex]\mathbf{E(x) =Days \times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{97}}[/tex]
There are 365 days in a year.
So, the expression becomes
[tex]\mathbf{E(x) =365\times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{97}}[/tex]
(b) Expected number of distinct birthdays
The probability that a person from the has his birthday on a certain day is:
[tex]\mathbf{p = 1 - (\frac{364}{365})^{100}}[/tex]
For 365 days, the expected number of distinct birthdays is:
[tex]\mathbf{E(x) = Days \times (1 - (\frac{364}{365})^{100})}[/tex]
There are 365 days in a year.
So, the expression becomes
[tex]\mathbf{E(x) = 365\times (1 - (\frac{364}{365})^{100})}[/tex]

Describe the domain and range. Graph the function. What do I do with the -3? The graph shows that y and x are at 0 so...?
Answers:
Domain: all real numbers
Range: [tex]y \le 6[/tex]
Graph is below.
====================================================
Explanation:
This is a piecewise function that is composed of two parts:
The first piece being y = x+6 but only when [tex]x \le 0[/tex]The second piece occurs when x > 0 and that piece is y = -3xThis piecewise function has split identities or multiple aliases so to speak. It all depends on what the x input is.
The graph is shown below.
The domain is the set of all real numbers since any x value will lead to some y output. Even x = 0 itself is allowed. Note the arrows indicate the graph stretches on forever to the left and to the right.
The range on the other hand isn't all real numbers. Instead, it's [tex]y \le 6[/tex] indicating that y = 6 is the largest y can get. Simply locate the highest point on the graph (similar to the concept of the vertex) and you'll spot the highest y value.
Side notes:
The domain in interval notation is [tex](-\infty, \infty)[/tex] which encompasses the entire real number line.The range in interval notation is [tex](-\infty, 6][/tex] where the square bracket includes the endpoint 6.Evaluate x + y - 4 when x = 4 and y = 1
Answer:

Step-by-step explanation:
Subsitute x and y:
x + y - 4

Eliminate the parameter, t, in the parametric equations, x = 3cos(t) and y = -6sin(t).
A) 2 x2 + y2 = 36
B) x2 + y2 = 2
C) 4 x2 + y2 = 36
D) x2 + y2 = 36
Recall that
cos²(t) + sin²(t) = 1
Then solving for cos(t) and sin(t), we have
x = 3 cos(t) ===> cos(t) = x/3
y = -6 sin(t) ===> sin(t) = -y/6
so that the above identity gives us
(x/3)² + (-y/6)² = 1
x²/9 + y²/36 = 1
36 (x²/9 + y²/36) = 36
(C) 4x² + y² = 36
The parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
We have two parametric equations:
x = 3cos(t) and
y = -6sin(t).
As we know, the trigonometric identity:
sin²θ + cos²θ = 1
For checking the option (A):
2x² + y² = 36
= 2(3cos(t))² + (-6sin(t))²
= 18cos²t + 36sin²t ≠ 36
Similarly, for checking the option:
4x² + y² = 36
= 4(3cost)² + (-6sint)²
= 36cos²t + 36sin²t
= 36(cos²t + sin²t)
= 36(1) = 36
Thus, the parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).

How many ways can you arrange 2 letters from the word S Q U A R E
Answer:
30
Step-by-step explanation:
WE use permutation for this question:
since the letters in SQUARE are all distinct, so：
[tex]^{6}P_{2} = 6*5=30[/tex]
The number of ways of arranging 2 letters from the word S Q U A R E is given by A = 15 ways
What are Combinations?The number of ways of selecting r objects from n unlike objects is given by combinations
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
Let the number of ways of arranging 2 letters from the word S Q U A R E be represented as A
Now , to select 2 letters from the 6 letters in the word SQUARE, without regard to order.
This is a combination problem, since the order in which we select the letters does not matter. Therefore, we can use the formula:
6 C 2 = 6! / 2!(6 - 2)!
= 6 x 5 / (2 x 1) x (4 x 3 / (2 x 1))
