Some think that Anna’s flowers are the tallest because the mean height of her flowers is the greatest.
Others think Anna’s flowers are the shortest because the median height of her flowers is the least.
The plots show the heights for each friend’s flowers.
Which is the most likely plot for Anna’s flowers?
Step-by-step explanation:

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
Answer:
It is wrong because she should simplify both sides of the equation,distribute, combine like terms,subtract and divide to get the final answer.
4x−2(3x−4)+4=−x+3(x+1)+1
Step 1: Simplify both sides of the equation.
4x−2(3x−4)+4=−x+3(x+1)+1
4x+(−2)(3x)+(−2)(−4)+4=−x+(3)(x)+(3)(1)+1(Distribute)
4x+−6x+8+4=−x+3x+3+1
(4x+−6x)+(8+4)=(−x+3x)+(3+1)(Combine Like Terms)
−2x+12=2x+4
−2x+12=2x+4
Step 2: Subtract 2x from both sides.
−2x+12−2x=2x+4−2x
−4x+12=4
Step 3: Subtract 12 from both sides.
−4x+12−12=4−12
−4x=−8
Step 4: Divide both sides by -4.
−4x−4=−8−4
x=2
Answer:
x=2
Answer:
it is in order to combine like terms on one side of the equation, the inverse operations must be used

Which is the graph of the function f(x) = 1/2x2+2x-6?
Answer:
This is how the graph would look like
Step-by-step explanation:
The graph of the function [tex]f(x) = 0.5x^{2} + 2x - 6[/tex] is attached below.
What is plotting of graph of a function?The graph of the function [tex]f(x) = 0.5x^{2} + 2x - 6[/tex] can be created by plotting a few coordinates that lie on the function.
When x = 0, y = -6
Coordinate = (0, -6)
When y = 0, [tex]0.5x^{2} + 2x - 6 = 0[/tex]
[tex]x^{2} + 4x - 12 = 0\\\\x^{2} + 6x - 2x - 12 = 0\\\\x(x+6) - 2(x+6) = 0\\\\(x-2)(x+6) = 0\\\\x = 2, -6\\[/tex]
Coordinates = (2,0), (-6,0)
Abscissa of vertex of graph = -b/2a = -2
Ordinate of vertex of graph = 0.5 *4 -4 - 6 = -8
coordinate = (-2, -8)

A local grocery store sells frozen fish sticks in packages of 18. If the cost for a package of 18 frozen fish sticks is $1.95, what is the approximate cost per frozen fish stick?
Answer:
$0.11 per frozen fish stick
Step-by-step explanation:
If a package of 18 fish sticks cost $1.95, to find the cost per frozen fish stick you need to divide $1.95 by 18
$1.95 / 18 frozen fish stick = $0.108 or $0.11 per frozen fish stick

Kylie is preparing for the science fair that will take place in six weeks. She has three plants that she has grown from seeds, which she considers to have height 0 centimeters, and she is measuring their heights as she applies different treatments to each. The second plant is receiving Plant Food B. After 3 weeks, it is 10 centimeters tall. If it continues growing at this rate, how tall will it be after 6 weeks?
The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
First we need two points (x, y) to obtain the slope.
Assuming height to be 'y' and weeks to be 'x'.
Therefore, (0, 0) and (3, 10) are the two points.
Slope(m) = (10 0)/(3 - 0).
Slope(m) = 10/3.
Slope(m) = 3.33
Now, To obtain the y-intercept.
10 = 3(3.33) + b
b = 0.01 Or neglegible.
Therefore y = 3.3x.
Now, In the 6th week, the height of plant B will be,
y = 3.33(6).
y = 19.98 or 20 cm.

Answer:
1.) 20z^5
2.) 8m^5 · 6p^7 · 3mp^0
Step-by-step explanation:
4z^3 · z^2 · 5z
first, multiply 4z · 1z = 4z and add the exponents 3 + 2 = 5
4z^5 · 5z
multiply 4z · 5z and keep the exponents
20z^5
2m^3p^4 · 4m^2p^3 · 3mp^0
find just the "m" variables: 2m^3 · 4m^2 and same as before multiply then add the exponents = 8m^5
now do the same for the "p" variables: 3p^4 · 2p^3 = 6p^7
and for the "mp" variable: 3mp^0
put it all together and this is the simplest form because we don;t know the values of the variables:
8m^5 · 6p^7 · 3mp^0
