Chloe compares the growth of plant species A and B. Part A What do the box plots tell you about the growth of a typical plant of each species? Choose the correct response. Plant B typically grows 1 cm taller than Plant A, since the range for Plant B is 1 cm greater. Plant B typically grows 1 cm taller than Plant A, since the IQR for Plant B is 1 cm greater. Plant A typically grows 1 cm taller than Plant B, since the median for Plant A is 1 cm greater. Plant A typically grows 1 cm taller than Plant B, since the mean for Plant A is 1 cm greater.
Answer:
Type A Type B
Median 52 grams 52 grams
Lower Quartile 49 grams 51 grams
Upper Quartile 57 grams 54 grams
Range 14 grams 8 grams
Interquartile Range 8 grams 3 grams
From this table we can see that both types of tomato have the same average mass because their medians are the same.
Comparing the medians and interquartile ranges shows that there is far more variation in the masses of the type A tomatoes, which means that the masses of type B are more consistent than those of type A.
However, comparing the two box and whisker plots, and the upper quartiles, shows that type A tomatoes will generally have a larger mass than those of type B.
Nevertheless, there will be some type A tomatoes that are lighter than any of type B.
Taking all this together, the gardener would be best advised to plant type A tomatoes in future as he is likely to get a better yield from them than from type B.

Hi
12. We use rule/law #2 of logarithms to condense log 2 - log 5.
True
O False
Answer:
log (2/5)
Step-by-step explanation:
The rule/law you have in mind is as follows: log a - log b = log (a/b).
Thus, your log 2 - log 5 = log (2/5).

reflection and translation.
Given:
The different transformation in the options.
To find:
The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.
Solution:
In option 1,
[tex](x,y)\to (y,x)[/tex]
It represents reflection across the line y=x.
In option 2,
[tex](x,y)\to (x,-y)[/tex]
It represents reflection across the x-axis.
In option 3,
[tex](x,y)\to (4x,4y)[/tex]
It represents dilation by scale factor 4 and the center of dilation is at origin.
In option 4,
[tex](x,y)\to (x+2,y-5)[/tex]
It represents translation 2 units right and 5 units down.
We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.
So, the perimeter of the figure and its image are same in the case of reflection and translation.
But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.
Therefore, the correct option is 3.

Step-by-step explanation:
Consider an equilateral triangle that is small enough to fit in your pocket. Now consider an equilateral triangle that is big enough to fill a movie screen! What must be true about the measure of each of the interior angles for these two triangles? Does the size of a triangle influence its angle measures? What about other polygons?
Answer:
Step-by-step explanation:
First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.
Second Question: No the size does not influence the size of the interior angle.
Third Question: That's true for all polygons. Size is not affect the interior angle size.
Alexis wrote 28 - 8 = 20. Then she
wrote 28 -8 + 9 = 20 – 9. Are her
equations balanced? Explain.
Answer:
no this is because 28-8+9=29 and 20-9=11
Step-by-step explanation:
Answer:
Her equation is not balanced.
Because 28 - 8 + 9 = 20 - 9
29 = 11 ( its not balanced)
She put the same symbol or sign on both side.Here she put different sign on both side .so this equation is not balanced.
Step-by-step explanation:
Which equation can be used to solve for x in the following diagram?
7xº
11x°
Answer:
7x° + 11x° = 90°
(Required equation)
Step-by-step explanation:
7x° + 11x° = 90°
(complementary angles)
18x° = 90°
18x = 90
x = 90/18
x = 5

Answer:
[tex]2(x+2)/x+1[/tex]
Step-by-step explanation:
Answer:
2( x +2 )
x+1
Step-by-step explanation:
to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]
since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators
combine x + x -2
factor [tex]x^{2}[/tex] - 4
to add or subtract expressions expand them and multiply by 1
have same denominator add them by adding their numerators
do the multiplications in 3 + ( x-2 )(x+2)
combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4
divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]
cancel out x-2 in both numerator and denominator
factor the expression that are not already factored
cancel out x-1 in both numerator and denominator
expand the expression

Problem: A pole is being held up with a 10 meter rope. The cable is making a 42° of elevation from the ground to
the top of the pole. What is the distance from the base of the pole to the base of the rope ? Round your answer
to the nearest tenth of a meter.
Answer:
x = 7.4
Step-by-step explanation:
cos(42°) = x/10 or distance from bases / rope length
Using the calculator find the value of cos(42°):
cos(42°) = 0.74 = x/10
Find x using the value of cos(42°):
x/10 = 0.74
x = 7.4

About all the sides are equal so we can say (10x + 44) side's triagle is twice than another triangle
So, 10x + 44 = 2( 8x - 23)
..... 10x +44 = 16x -46
...... X = 15
