Mrs. Hull calculated the measure of central tendencies for the two plants in her science class. The measures are recorded below.
Which measure of central tendency would be the best for Mrs. Hull to use if she wanted to argue that there is a difference between the plants?
The appropriate measure of central tendency is one that shows
difference and is suitable for a scale that is nominal.
Response:
The measure of central tendency to use is the mode.How can the appropriate measure of central tendency be selected?The mean is the sum of the measurements divided by the number count
of the plants.
The mode is the measurement that has the highest frequency.
The median is the measurement of the middle plant when arranged in a
given order according to size.
To argue that there is a difference between the plants, the measure of
central tendency to use is the mode, given that the data involves
measurements which can be expressed in a nominal scale.

This is how a taxi company works out the cost a journey. There is a fixed charge of $6 plus $2 per kilometer.
Write the formula for the cost of the journey in:
Words
Answer: 6+2x
Step-by-step explanation:
6 is the fixed cost so you add six regardless of how many kilos you travel. You add the 2x because they charge 2 dollars for every extra kilometer. The x is kilometers(which you don’t know how many you travel.) so you add 6+2x to get the cost.
Linear equation is equation in which each term has at max one degree. The formula for the cost of the journey is y = $6 + $2(x).
What is linear equation?Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form,
y = mx + c
Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.
The given condition can be modelled using a linear relationship.
It is given that there is a fixed charge of $6 and an additional charge of $2 per kilometre. Therefore, the total charge,y can be modeled as,
y = $6 + $2(x)
where x represents the number of kilometres
The formula for the cost of the journey in Words is 6 plus two times of x, where x represents the number of kilometres.
Hence, the formula for the cost of the journey is y = $6 + $2(x).

Quadrilateral A'B'C'D prime is the result of dilating quadrilateral ABCD about point P by a scale factor of 5/3
Answer:
1. False
2. False
Step-by-step explanation:
The statement "BC and B'C' are on the same line" is false, and the statement "the lengths of CD and C'D' are equal" is false.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
Quadrilateral A'B'C'D prime is the result of dilating quadrilateral ABCD about point P by a scale factor of 5/3
To determine whether each claim about the properties of ABCD and A'B'C'D' is true or false.
The points in the image by multiplying the coordinates of the points in the preimage by the scale factor.

4x + 2y = -12 3x + y = -10 please help system by substitution.
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
The markup at Total Jewelry is 70%. If the wholesale price of a necklace is $130, what will the store charge as the retail price for the necklace?
Answer:
$221
Step-by-step explanation:
The original percent is always 100%. Add the markup, 70% to 100% to find the total percent charged.
100% + 70% = 170%
Change 170% to a decimal by moving the decimal two places left. 170% = 1.70
Multiply the decimal and the wholesale price.
$130 x 1.70 = $221
Answer: I am assuming that you are using edge so it is C. 221. The other person who answered it has a great explanation so you can go off of theirs.

Explain how to tell which side of a right triangle is adjacent to an angle and which side is the hypotenuse.
Step-by-step explanation:
In the diagram, AB is adjacent to Angle"a", because if we don't consider hypotenuse, it is the only associated segment to the angle.
The segment opposite to the right angle is called Hypotenuse.
The last one, AC segment, is called the Opposite because it is the opposite to Angle"a".
If we look at it from AngleC, however, its Adjcent will be segment AC, and Opposite will be segment AB.

Mrs. Eaton sometimes makes her melon salad for special events.
When she made it a couple months ago, she used 22 kilograms of honeydew melon and 22 kilograms of watermelon, which cost her \$ 4$4.
Today, she used 11 kilogram of honeydew melon and 22 kilograms of watermelon, spending a total of \$ 3$3 on the melons.
Assuming that the prices of the melons haven't changed, how much does a kilogram of each type of melon cost?
Answer:
honeydew: $2.00 per kgwatermelon: $0.50 per kgStep-by-step explanation:
The cost per kilogram is found by dividing cost by kilograms:
honeydew:
($4)/(2 kg) = $2/kg
Honeydew costs $2 per kilogram.
__
watermelon:
Let w represent the cost per kg of watermelon. The total value of the second purchase was ...
(1 kg honeydew)×($2/kg) +(2 kg watermelon)×(w) = $3
$2 +2w = $3
2w = $1 . . . . . . . . . . . . subtract $2
w = $1/2 = $0.50 . . . . divide by 2
The watermelon cost $0.50 per kilogram.

Value of [tex]x[/tex]is [tex] - 12[/tex].
Final Answer is [tex]480[/tex]
Step-by-step explanation:
Assume that:
First number = x
Second number = 20 - x
Putting the given conditions,
[tex]2x^{2} + 3(20 - x)^{2} [/tex]
Putting the formula (a-b)²=(a²+2ab+b²) in (20-x)²,
[tex]2 {x}^{2} + 3(20^{2} - 2 \times 20 \times x + {x}^{2})[/tex]
[tex] = > 2 {x}^{2} + 3(400 - 40x + x^{2})[/tex]
Opening the brackets,
[tex]2 {x}^{2} + 3 \times 400 - 3 \times 40x + 3 \times {x}^{2} [/tex]
[tex] = > 2 {x}^{2} - 1200 - 120x + 3{x}^{2}[/tex]
[tex] = > (2x^{2} + 3 {x}^{2}) - 120x + 1200[/tex]
[tex] = > 5 {x}^{2} - 120x + 1200[/tex]
[tex]As \: x= - \frac{b}{2a}[/tex]
[tex] = > - \frac{120}{2 \times 5}[/tex]
[tex] = > - \frac{120}{10} [/tex]
[tex] = > - 12[/tex]
Now substituting the value of x in 5x²-120x+1200,
[tex] = > (5 \times {12}^{2} )-(120 \times 12)+1200[/tex]
[tex] = > (5 \times 144)-(1440)+1200[/tex]
[tex] = > 720 - 1440 + 1200[/tex]
[tex] = > 720 - (1440 - 1200)[/tex]
[tex] = > 720 - 240[/tex]
[tex] = > 480[/tex]
