Answer:
the number of hours in a week Jope, who is not at work, is 102 hours
Step-by-step explanation:
call X is the number of hours in a week Jope is not at work.
=> the number of hours in a week = X + the number of work hours in a week
=> 6*24 = X + 42
=> X = 6*24 - 42

c. if has translational symmetry, what is shape is getting repeated
Answers

Answer:
b) rotational symmetry: multiples of 120°
Step-by-step explanation:
The figure does not have a line of symmetry, or a point of symmetry. However, rotating it 1/3 turn (120°) will make it look like itself. Hence, it has rotational symmetry of degree 3. A rotation of any multiple of 120° will map the figure to itself.

Lucy wants to multiply 88 x 808. She says that all she has to do is find 8 x 808 and then double that number. Explain why Lucy's method will not give the correct answer. Then, show how to find the correct answer.
Answers
The multiplication that Lucy has to make is:
\(88\times808\)If she multiplies 8x808 and then multiplies the result by 2, she will not be finding 88x808, instead, she will be finding 16x808, (because 8x2 is 16):
\(2(8\times808)=16\times808\)Thus, with that method, she will not get the correct result.
Let's find the correct method:
Going back to the original multiplication she has to make:
\(88\times808\)We can express the number 88 as 11x8:
\((11\times8)\times808\)And we represent this as follows:
\(11(8\times808)\)And we have found the correct method: she has to find 8x808 and then multiply the result by 11.
Answer: Find 8x808 and multiply the result by 11.
What is the domain of the function y = square root x+6 -7?
Answers
Answer:
-6 ≤ x < ∞
Step-by-step explanation:
You want the domain of the function y = √(x+6) -7.
DomainThe domain of a function is the set of x-values for which the function is defined. On a graph, it is the horizontal extent of the graph.
The square root function is undefined for negative arguments, so that limits the domain of the given function:
x+6 ≥ 0
x ≥ -6 . . . . . domain of the given function
__
Additional comment
When the domain is written in interval notation, both the left and right ends of the interval must be specified.
[-6, ∞)
The square bracket identifies -6 as being part of the domain. The parenthesis is used with ∞, because that number has no specific value.

Use the Distributive Property to factor out the GCF.
−26n + 7n + 13n =
Answers
Answer:
To factor out the GCF from the given expression, we can use the distributive property. This property states that we can distribute a common factor to all of the terms in an expression by multiplying the common factor by each term separately. In this case, the common factor is n, so we can distribute it to each term by multiplying it by -26, 7, and 13:
(-26n * n) + (7n * n) + (13n * n)
This gives us:
-26n^2 + 7n^2 + 13n^2
We can then combine like terms by adding the coefficients of n^2:
(-26 + 7 + 13) * n^2
This gives us the final result:
-6 * n^2
Therefore, we can factor out the GCF of -6n^2 from the given expression.

Suppose a hexagonal traffic sign is dilated by a scale factor of 2.5 about its center. Which statement is true? A. The dilated sign will have corresponding line segments that are congruent to those of the pre-image and corresponding angles that are proportional to that of the pre-image. B. The dilated sign will have corresponding line segments that are proportional to those of the pre-image and corresponding angles that are congruent to that of the pre-image. C. The dilated sign will have corresponding line segments and angles that are congruent to those of the pre-image. D. The dilated sign will have corresponding line segments and angles that are proportional to the pre-image but not congruent
Answers
Hexagonal implies that the traffic sign has six straight sides. But dilating it changes its length of sides, but not its angles. So that the statement that is true is option B.
i.e B. The dilated sign will have corresponding line segments that are proportional to those of the pre-image and corresponding angles that are congruent to that of the pre-image.
Dilation involves increasing or decreasing the line segments of a given shape by a scale factor. This process do not affect the measure of the internal angles of the shape.
Given a hexagonal traffic sign in the question, this implies that the traffic sign has six sides. Dilating it by a scale factor of 2.5 about its center would affect its length of sides. So that the statement that is true is option B.

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die.

What is the difference in the population?The numbers are written in scientific notation. Scientific notation is a method that is used in mathematics to compress large numbers. In order to write a number in scientific notation, the number is written as a decimal number between 1 and 10 and multiplied by a power of 10. For example, 3 x 10² is equivalent to 300
Subtraction is the mathematical operation that is used to determine the difference between two or more numbers.
8.59 x \(10^{4}\) - 3.2 x 10³
(0.859 x \(10^{4 - 1}\)) - ( 3.2 x 10³)
(0.859 x 10³)- (3.2 x 10³)

The equation of the linear function is y=8x+(-8).
What do you mean by equation?
A mathematical statement with two expressions that have the same value and the sign "equal to" between them is called an equation. Take the example of 3x + 5 = 15. Equations can be of several sorts, including linear, quadratic, cubic, and others.
According to data in the given question,
We have points (0,-8) and (1,0), thus
\(m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\=\frac{(0-(-8))}{1-0} \\=8\)
Then
y=8x+b
Points (0,-8) means that when x=0, y=-8 and we use this to find b,
y=8x+b
-8=8(0)+b
-8=0+b
b=-8
So, y=8x+(-8)
Therefore, the equation of the linear function is y=8x+(-8).

Write a polynomial function of the least degree with integral coefficients that have the given zeros. 4,-2+root5
Answers
If the given zeros are 4 and -2+√5, then the polynomial function of the least degree with integral coefficients that has these zeros can be obtained by using the fact that if a polynomial has a root at x=a, then it has a factor of (x-a).
Therefore, the polynomial function with these zeros can be written as:
(x - 4)(x - (-2+√5))(x - (-2-√5))
Expanding the factors using the difference of squares, we get:
(x - 4)((x + 2) - √5)((x + 2) + √5)
Simplifying the expression further, we get:
(x - 4)((x + 2)^2 - 5)
Expanding the square, we get:
(x - 4)(x^2 + 4x - 1)
Therefore, the polynomial function of the least degree with integral coefficients that has the zeros 4 and -2+√5 is:
f(x) = (x - 4)(x^2 + 4x - 1)
Expanding the factors, we get:
f(x) = x^3 + 4x^2 - x - 16

The empirical rule regarding mean and standard deviation is that
Around 68% of scores are between 40 and 60.Around 95% of scores are between 30 and 70.Around 99.7% of scores are between 20 and 80.Therefore between mean and +2 standard deviation or between mean and -2 standard deviation you will find approximately 95/2 = 47.5% of the values
Between mean and ± 3 standard deviations you will find approximately 97.5/2 = 48.75% of the values
Therefore between 2 standard deviations above and 3 standard deviations below you will find approximately 47.5 + 48.75 = 96.25% of values

Answers
If a parabola opens up, the vertex is the lowest point on the graph, hence it has a minimum value.
If a parabola opens down, the vertex represents the highest point on the graph, hence we can say it has a maximum value.
The range of a graph is the set of all possible y-values.
• If a parabola has a maximum value, that means it opens down. Since it opnes down, the range of the parabola will be all outputs, ,less than, that maximum value.
The parabola above has a maximum at y = 10.
The range of the graph will be all outputs less than 10(maximum value).
Therefore, if a parabola has a maximum value then the range will be all outputs less than that maximum value.
• If a parabola has a minimum value, that means it opens up. Since it opens up, all set of possible y-values will be greater than the minimum value.
Therefore, if a parabola has a minimum value then the range will be all outputs greater than the minimum value.
