Answer:
10.9
Step-by-step Explanation:
The Mean Absolute Deviation of a given data set tells us how far apart, on average, each data value is to the mean of the data set.
The smaller the Mean Absolute Deviation of a given data set is, the closer each data value is to the mean. This also implies less variability of the data set.
Invariably, the smaller the M.A.D, which connotes less variability, the more consistent the data set is.
Therefore, a M.A.D of 10.9 represents more consistency than a M.A.D of 15.2

Answer:
Part A:
Two types of translation are;
1) Horizontal translation left T(0, 8),
2) Vertical translation T(16, 0)
Part B:
For the horizontal translation transformation, k = 8
For the vertical translation transformation, k = 16
Part C:
For the horizontal translation transformation, the equation is f(x + 8) = g(x)
For the vertical translation transformation, the equation is f(x) + 16 = g(x)
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
Part A
We can shift f(x) up to g(x)
or we can shift f(x) to the left into g(x)
Part B
y = f(x) + k k > 0 moves it up
f(x) goes from -1 to 17 for a distance of 18 units
We are moving up 18 units
k = 18
y = f(x + k) k> 0 moves it left
We are moving to the left from 0 to -6 units for a distance of 6 units
k = 6
Part C
Up:
g(x) = f(x) +18
Left:
g(x) = f(x+6)
On a coordinate plane, a piecewise function has 3 lines. The first line has an open circle at (negative 9, negative 2), continues horizontally at y = negative 2, then has an open circle at (0, negative 2). The second line has an open circle at (0, 1), continues up with a positive slope, then has an open circle at (4, 9). The third line has an open circle at (4, negative 2), continues down with a negative slope, then has an open circle at (8, negative 4).
What is the domain indicated on the graph for each
Answer: D: x = (-9, 0) U (0, 4) U (4, 8)
Step-by-step explanation:
Line 1: y = -2 where -9 < x < 0
Line 2: y = 2)x + 1 where 0 < x < 4
Line 3: y = -(1/2)x + 6 where 4 < x < 8
Domain represents the x-values. Since all of them are open dots, the intervals are strictly less than (<).
-9 < x < 0 and 0 < x < 4 and 4 < x < 8 is the union of these intervals
-9 < x < 0 U 0 < x < 4 U 4 < x < 8

Answer:
The equation of the quadratic function shown is;
x^2+ 2x -3
Step-by-step explanation:
Here in this question, we need to know the quadratic equation whose graph was shown.
The key to answering this lies in knowing the roots of the equation.
The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.
The graph crosses the x-axis at two points.
These are at the points x = -3 and x = 1
So what we have are;
x + 3 and x -1
Multiplying both will give us the quadratic equation we are looking for.
(x + 3)(x-1) = x(x -1) + 3(x-1)
= x^2 -x + 3x -3 = x^2 + 2x -3
solve 4w–3w+2w=24
Please
We need to simplify the left side first.
On the left side, all the terms can be combined.
So 4w - 3w + 2w is 3w.
So we have 3w = 24.
Next, dividing both sides by 3, we have w = 8.
So our solution is w = 8.
Answer
[tex] \boxed{ \huge{ \bold{ \sf{ \boxed{w = 8}}}}}[/tex]
Step by step explanation
[tex] \sf{4w - 3w + 2w = 24}[/tex]
Collect like terms
⇒[tex] \sf{w + 2w = 24}[/tex]
⇒[tex] \sf{3w = 24}[/tex]
Divide both sides of the equation by 3
⇒[tex] \sf{ \frac{3w}{3} = \frac{24}{3} }[/tex]
Calculate
⇒[tex] \sf{w = 8}[/tex]

A. add 3 to both sides of the equation
B. subtract 3 from both sides of the equation
C. add 6 to both sides of the equation
D. subtract 6 from both sides of the equation
Answer:B
Step-by-step explanation:
From calculating the equations below, we find that all sections have m equal to negative three.
According to the second option, it is most likely because six is added.
B is the midpoint of AC. What is the value of x if AC = 52 and AB = 3x - 4
Answer:
x = 10
Step-by-step explanation:
Since B is the midpoint of AC then AB = BC = 3x - 4 and
AB + BC = AC , thus
3x - 4 + 3x - 4 = 52, that is
6x - 8 = 52 ( add 8 to both sides )
6x = 60 ( divide both sides by 6 )
x = 10

What is the equation of the line that is
parallel to y = 4x + 3 and passes through
the point (2,6)?
HELP! answer if you can!
Hi there! :)
Answer:
[tex]\huge\boxed{y = 4x - 2}[/tex]
Given line with an equation of y = 4x + 3
Parallel lines contain equivalent slopes, so a parallel line to the given equation would contain a slope of m = 4.
Plug in the coordinates of the point given, along with the slope into the equation y = mx + b where:
m = slope
y = y-coordinate of point
x = x-coordinate of point
Solve for the 'b' value, or y-intercept:
y = mx + b
6 = 4(2) + b
6 = 8 + b
b = -2
Rewrite the equation as slope-intercept form:
y = 4x - 2
Answer:
When you see the word "parallel", you know the new line will have the same slope.
parallel to y = 4x + 3
So, the new line will have a slope of 4
"Indicate the region where y≥ 4x + 3
Plot y= 4x + 3 by finding the points that make it true. For example, (y = 0, x = 3/4), (y = 2, x = 2) and so on.
y = 4x + b
b is the y intercept ( point y when x = 0)
Insert new coefficients:
+2 = 4(0) + b
b = +2
y = 4 + 2

what is the coefficient of x in the equation of 32+2x=10
solve after finding the coefficient
Answer:
x= -11
Step-by-step explanation:
the coefficient is variable that appears before a number . bearing this in mind, the coefficient of x is therefore 2 .
the value of x is:
>32+2x=10
>2x=10-32
>2x= -22
>x= -11
Answer:
Step-by-step explanation:
Coefficient of x = 2
32 + 2x = 10
Subtract 32 from both side
32 + 2x -32 = 10 - 32
2x = - 22
Divide both sides by 2
2x/2 = -22/2
x = -11

Peter attempted to use the divide-center method to find the line of best fit on a scatterplot.
What was his mistake?
He had a different number of points to the left of the vertical line than to the right of the vertical line.
He had a different number of points above the line of best fit than below the line of best fit.
He didn’t approximate the center of the cluster located on the left side of the vertical line and of the cluster located on the right side of the vertical line.
He didn’t connect the centers of the clusters on the left side and right side of the vertical line to produce the line of best fit.
Answer:
He had a different number of points to the left of the vertical line than to the right of the vertical line.
Step-by-step explanation:
Divide-center method is the method which involves dividing the data on the graph into two equal parts and then fin the line of best fit. The center of each group is approximated and then a line is constructed between two centers which is estimated as line of best fit.
3 pizzas cost $22.50,how much does 1 pizza cost?

One hundred people, ages 11-15, were randomly surveyed to find their opinion of their favorite leisure time activity. Sixty-four percent of them said they liked to spend time watching TV. If there are 1500 students in your school, about how many of them would you predict would enjoy watching t.v. A.2343 B.960 C.640 D.500
Answer:
If there are 1500 students in your school then 960 students would enjoy watching TV
Step-by-step explanation:
Step 1: We know that 64% of kids aged from 11 to 15 enjoy watching TV and there is 1500 students in your school
Step 2: We now want to find 64% of 1500, we can rewrite 64% as 0.64. We multiple 1500 by 0.64 to find out how many students enjoy watching TV
0.64 x 1500 = # of students who like watching TV
960 = # of students who like watching TV
Therefore out of 1500 students, 960 would enjoy watching TV

I was told that 3x- was -12 but I can’t understand how they got -12:/
Answer:
6
Step-by-step explanation:
They got 3x-12 because they took
3(x - 4)
and they distrubuted the 3 to the numbers in parenthesis,
how they did this was they multiplied 3 by x and got 3x then they kept the subtraction sign that is in the parenthesis. Then they multiplied 3 by the 4 and got 12.
then the equation was 3x - 12/2 = 6
Answer:
x=8
Step-by-step explanation:
[tex] \frac{3(x - 4)}{2} = 6[/tex]
Multiply 3 by what's in the bracket
[tex] \frac{3x - 12}{2} = 6[/tex]
Multiply through by the LCM of all the denominators
[tex] \frac{2(3x - 12)}{2} = 2 \times 6[/tex]
=The numerator 2 will cancel the denominator 2
[tex]3x - 12 = 12[/tex]
Grouping like terms
[tex]3x = 12 + 12[/tex]
Dividing both sides by 3
[tex] \frac{3x}{3 } = \frac{24}{3} [/tex]
[tex]x = 8[/tex]
