Which of the dot plots shows a symmetric distribution?
Answers
The dot plot that has a symmetric distribution is option b.
What is a dot plot?A dot plot is a graph that has similarities with a histogram. A dot plot is made up of a number line and dots. A dot plot is used to represent the frequency of a data set.
The dots in the dot plot represent the frequency of the data. The greater the frequency of a data, the greater the number of dots the number has. For example, if a number has a frequency of 6, it would have 6 dots have it.
A dot plot is symmetric if the left side of the graph and the right side of the graph are mirror images of each other. A dot plot is skewed to the left if there are more dots on the left side of the graph. A dot plot is skewed to the right if there are more dots on the right side of the graph.

From division it is possible to find x= -4.
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=7x+2. Where:
a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex] .
b= the constant term that represents the y-intercept.
For the given example: a=7 and b=2.
For solving linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.
Therefore for -12x=48, you should follow the steps below

The total amount of money (in cents) in x quarters, (x+2) dimes, and 2x nickels. (Hint: The value of a quarter is 25 cents, the value of a dime is 10 cents, and the value of a nickel is 5 cents.)
HELP PLEASEEE !
Answers
The algebraic expression that represents the total amount of money in terms of x is:
y = 45*x + 20
How to write the algebraic expression?Here we want to find the total value (in cents) of:
x quarters.x + 2 dimes2x nickels.The total value will be given by the linear equation:
y = x*25 + (x + 2)*10 + (2x)*5
Where y represents the total value in cents.
Now we can simplify that equation to get:
y = x*25 + (x + 2)*10 + (2x)*5
y = x*25 + x*10 + 20 + x*10
y = 45*x + 20
This is the algebraic expression we wanted to get.

changes color every 12 seconds Strand 2: changes color every 13 seconds
Both strands just changed color. After how many seconds will the strands change color at the same time again?
The strands will change color at the same time again after
seconds.
Answers
After 156 seconds the strands will change color at the same time again.
As strand 1 changes color every 12 seconds and Strand 2 .changes color every 13 seconds. we are provided that both strands just changed color and we need to find that After how many seconds will the strands change color at the same time again
To know After how many seconds will the strands change color at the same time again we need to find the least common multiple (LCM) of 12 second and thirteen seconds
The factors of 12 = 2*2*3
The factors of 13 = 1 *13
LCM =2 * 2* 3*13 = 156
Hence, After 156 seconds the strands will change color at the same time again
Correct question is Strand 1 changes color every 12 seconds Strand 2: changes color every 13 seconds . Both strands just changed color. After how many seconds will the strands change color at the same time again?

Step-by-step explanation:
Answer:
y = 3x² + 6x - 45
Step-by-step explanation:
given roots x = a and x = b then the factors are (x - a) and (x - b)
then the quadratic is the product of its factors
y = a(x - a)(x - b) ← a is a multiplier
here x = - 5 and x = 3 with a = 3 , then factors are
(x - (- 5)) and (x - 3) , that is (x + 5) and (x - 3) , then
y = 3(x - 3)(x + 5) ← expand factors using FOIL

Megan cuts pieces of colored felt to
create a logo of a sun behind a
mountain peak. Determine the
approximate total amount of felt used
in the logo.
Answers
The approximate total amount of felt used in the logo is 334.34 square cm
How to determine the approximate total amount of felt used in the logo?We have the following parameters on the logo:
Shapes = Semicircle and Triangle
Where
Semicircle:
Diameter = 18 cm
Triangle
Base = 16 cm
Height = 10 cm
The approximate total amount of felt used in the logo is calculated as
Amount = Area of semi-circle + Area of triangle
This gives
Amount = π(d/2)^2 + 0.5bh
So, we have
Amount = 3.14 * (18/2)^2 + 0.5 * 16 * 10
Evaluate
Amount = 334.34
Hence, the approximate total amount of felt used in the logo is 334.34 square cm

The piecewise function for the discounted price of the purchase is given by:

For $300≤x<$1,000, the discount is of 4%, hence the discounted price is 96% of the original price, that is:
D(x) = 0.96x, 300≤x<1,000
For $1,000≤x<$3,000, the discount is of 5%, hence the discounted price is 95% of the original price, that is:
D(x) = 0.95x, 1,000≤x<3,000.
For $3,000≤x<$5,000, the discount is of 6%, hence the discounted price is 94% of the original price, that is:
D(x) = 0.94x, 3,000≤x<5,000.
For $5,000≤x, the discount is of 10%, hence the discounted price is 90% of the original price, that is:
D(x) = 0.9x, 5,000≤x.

Determine if the conjecture is true or false.
If False give a counterexample.
Answers
a = 1, b = 2 is a counterexample, and with that, we conclude that the conjecture is false.
Is the conjecture true or false?Here we have the conjecture:
"For any two integers a and b, (a - b)^2 = (a^2 - b^2)"
Notice that if we find a single pair of integers a and b such that the equality in the conjecture is false, then we have found a counterexample and that is enough to conclude that the conjecture is false.
If we define=
a = 1
b = 2
Replacing that in the equation of the conjecture we get:
(1 - 2)^2 = (1^2 - 2^2)
(-1)^2 = 1 - 4
1 = -3
This is false, then a = 1, b = 2 is a counterexample, and with that we conclude that the conjecture is false.
