What is the mean absolute deviation?
Mean absolute deviation (MAD) is a statistical measure of how much the data values in a set deviate from the mean of the set.
Given options are
a. Ratings with a high mean and a high mean absolute deviation
b. Ratings with a high mean and a low mean absolute deviation
c. Ratings with a low mean and a high mean absolute deviation
d. Ratings with a low mean and a low mean absolute deviation
The manager at Frydays wants to receive consistent, positive ratings by customers on social media over the next month. Consistency means that the ratings are close to each other, and positive ratings mean that they are higher than average. Therefore, the goal is to have ratings with a high mean and a low mean absolute deviation.
The mean is a measure of central tendency that represents the average rating of customers, and a high mean indicates that the ratings are positive. The mean absolute deviation (MAD) is a measure of dispersion that represents how spread out the ratings are from the mean. A low MAD indicates that the ratings are close to each other and consistent.
Hence, The correct answer is (b) Ratings with a high mean and a low mean absolute deviation.

The values of the marked angles: angle 2, angle 3, angle 4, angle 5, angle 6, angle 7, angle 8 are 28°, 28°, 152°, 152°, 28°, 28°, 152°.
What is an angle?When two lines or rays meet at a point, then the geometrical figure is formed, is called an angle.
Given, angle 1 = 152°
We know, angle 1 + angle 2 is 180°. (supplementary angles)
Therefore, angle 2 = (180° - 152°) = 28°.
Again, angle 2 = angle 3. (opposite angles)
Therefore, angle 3 = 28°.
Similarly, angle 1 = angle 4
Therefore, angle 4 = 152°.
Now, angle 1 = angle 5 (corresponding angle)
Therefore, angle 5 = 152°.
Now, angle 2 = angle 6 (corresponding angle)
Therefore, angle 6 = 28°.
Now, angle 3 = angle 7 (corresponding angle)
Therefore, angle 7 = 28°.
Now, angle 4 = angle 8 (corresponding angle)
Therefore, angle 8 = 152°.

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.
5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.
How to verify that RSTU is a trapezoid?In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;
RU ║ ST
Slope of side RU = Slope of side ST
Slope of RU = (y₂ - y₁)/(x₂ - x₁)
Slope of RU = (1 + 3)/(5 + 3)
Slope of RU = 4/8
Slope of RU = 0.5.
Slope of RS = (y₂ - y₁)/(x₂ - x₁)
Slope of RS = (-9 + 3)/(-4 + 3)
Slope of RS = -6/-1
Slope of RS = 6.
Slope of ST = (y₂ - y₁)/(x₂ - x₁)
Slope of ST = (-2 - 1)/(10 - 5)
Slope of ST = -3/5
Slope of ST = -0.6.
Slope of UT = (y₂ - y₁)/(x₂ - x₁)
Slope of UT = (-2 + 9)/(10 + 4)
Slope of UT = 7/14
Slope of UT = 0.5.
Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.
Question 5.
In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance RT = √[(-2 + 3)² + (10 + 3)²]
Distance RT = √170 units.
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance US = √[(5 + 4)² + (1 + 9)²]
Distance US = √181 units.
Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.

Which statement about the value of √90 feet is true?
A. √90 feet is between 9 feet and 10 feet but is closer to 9 feet.
B. √90 feet is between 9 feet and 10 feet but is closer to 10 feet.
C. √90 feet-45 feet
D. √90 feet = 8100 feet
Answer:
The correct answer is A.
Step-by-step explanation:
The correct answer is A.
To find the length of one side of the square, we need to take the square root of the area. Therefore, the square root of 90 is approximately 9.49 feet. Since this value falls between 9 feet and 10 feet, but is closer to 9 feet, the statement "√90 feet is between 9 feet and 10 feet but is closer to 9 feet" is true. So, Jimmy should cut the carpet to 9.49 feet to fit the square-shaped room.

Answer:
Step-by-step explanation:
Find an equation for the surface with all points which are equidistant of (−1,0,0)and the plane x=1. Draw the surface.
The equation for the surface with all points which are equidistant of (−1,0,0)and the plane x=1 is x² - 2x + y² + z² = 2.
In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of two sides separated by an equal sign (=).
To start with, let's consider the given information. We have been given that all points on the surface are equidistant from (-1,0,0) and the plane x=1. This means that the distance between any point on the surface and (-1,0,0) is the same as the distance between that point and the plane x=1.
We can use the formula for the distance between a point and a plane to derive an equation for the surface. The formula for the distance between a point (x1, y1, z1) and a plane Ax + By + Cz + D = 0 is given by:
distance = |Ax1 + By1 + Cz1 + D| / √(A² + B² + C²)
In our case, the plane is x=1, which can be written as x - 1 = 0. So, A=1, B=0, C=0, and D=-1. The point (-1,0,0) can be substituted as x1=-1, y1=0, and z1=0.
We can simplify the distance formula to:
distance = |x-1|
Now, since all points on the surface are equidistant from (-1,0,0) and x=1, we can set up the following equation:
|x-1| = √( (x+1)² + y² + z² )
Squaring both sides and simplifying, we get:
(x-1)² = x² + 2x + 1 + y² + z²
Rearranging and simplifying, we get the final equation for the surface:
x² - 2x + y² + z² = 2
This is the equation of the surface that contains all points that are equidistant from (-1,0,0) and x=1.

Answer:
x = -2 ±i(√6)/3
Step-by-step explanation:
The formula for the solution of ax²+bx+c=0 is ...
\(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)
When your equation is written in standard form, it is ...
3x² +12x +14 = 0
so the values needed in the formula are a=3, b=12, c=14.
\(x=\dfrac{-12\pm\sqrt{12^2-4(3)(14)}}{2(3)}=\dfrac{-12\pm\sqrt{-24}}{6}=\dfrac{-12\pm2i\sqrt{6}}{6}\\\\\boxed{x=-2\pm\dfrac{\sqrt{6}}{3}i}\)
The cost per guest of catering an event of no more than 150 people is modeled by the function () = 45 + 15. The number of guests is modeled by the function () = 150 − , where x represents the number of guests fewer than 150 that attend. Evaluate ( ∙ )() and interpret what it means in the context of the problem. Show all work
C(N(x)) = 45 + 15(150 - x) = 45 + 2250 - 15x = 2295 - 15x. C(N(x)) = 2295 - 15x, which equals $2295 minus $15 for each guest fewer than 150. Therefore, $795 would be needed to prepare for 50 guests.
What does an arithmetic expression mean?A group of terms joined with the operations +, -, x, or form an expression, such as 4 x 3 or 5 x 2 3 x y + 17. A statement that starts with an equals sign, such as 4 b 2 = 6, says that two statements are equal in value and is known as an equation.
The functions are: C(x) = 45 plus 15x (Cost per guest)
N(x) = 150 - x (Number of guests)
We must simplify and replace the formula for N(x) with C(x) in order to evaluate C(N(x)):
C(N(x)) = 45 + 15(150 - x) = 45 + 2250 - 15x = 2295 - 15x
The expense of catering for x guests who are less than 150 is denoted by the expression 2295 - 15x.
The expense of catering a celebration for x guests fewer than 150 is denoted by the formula: C(N(x)) = 2295 - 15x, which equals $2295 minus $15 for each guest fewer than 150. This expression provides the total expense of catering for the number of guests defined by the function N.(x). For instance, if the event has 50 guests, then x = 100 and the expense of catering for 50 guests.
C(N(100)) = 2295 - 15(100)
= 2295 - 1500

In ABCD, BC – DB and m B = 147. Find mZD.
Since sides BC and DB are equal, then we deduce angle C and angle D have the same value. From the information given we know that the angle B is 147°, therefore we can use the following equation (knowing that the addition of three angles of a triangle is equal to 180°)
C + D + B = 180°
2D + 147° = 180° ( Since C=D)
2D = 180° - 147° ( Transposing 147° to the other side of the equation)
