Minnie wants to know if the number of words on a page in her planetary science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book. Mean Median Mean Absolute Deviation Planetary science 48.9 41 9.2 Math 34.5 44 1.9 She claims that because the mean number of words on each page in the planetary science book is greater than the mean number of words on each page in the math book, the planetary science book has more words per page. Based on the data, is this a valid inference? No, because there is a lot of variability in the planetary science book data. Yes, because there is a lot of variability in the planetary science book data. Yes, because the mean is larger in the planetary science book. No, because the mean is larger in the planetary science book.

No, Minnie is incorrect, because there is a lot of variability in the Planetary science book data.
Is this a valid inference?We know that, for 25 samples of each book, we have:
Book mean median MAD
Planetary science 48.9 41 9.2
Math 34.5 44 1.9
The claim, is that "the Planetary science book as more words per page"
Notice that even if we subtract the mean standard deviation from the mean in the Planetary science case:
48.9 - 9.2 = 39.7
And we add these in the math case:
34.5 + 1.9 = 36.4
So, even considering the variability, the Planetary science book has more words per page.
The value in the Planetary science case is still larger, so, only with this, we conclude that her claim is not valid.

(5ab-9a-4) - (-4ab + 5)
Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.
Which ordered pair is a viable solution if x represents the number of books he orders and y represents the total weight of the books, in ounces?
Answer:
The answer is "(0,0)"
Step-by-step explanation:
In the given some information is missing that is point so, the correct answer to this question can be described as follows:
book Number = x
overall Book weight = y
Neither x nor y can be negative. We have to be positive values, then.
Since x indicates the number of books, that must be a positive integer. It can not be a decimal number or fractional number.
So the only viable solution from the given options is (0, 0).

Triangle XYZ has vertices X(2,4), Y(3,4) and Z(3,8). Suppose you reflect this across the y-axis, then dilate it with a scale factor of 2 with the origin as the center of dilation. What are the coordinates of the resulting triangle X″Y″Z″? answers: A) X″(–4,8), Y″(–6,8), Z″(–6,16) B) X″(2,–4), Y″(3,–4), Z″(3,–8) C) X″(–2,4), Y″(–3,4), Z″(–3,8) D) X″(4,–8), Y″(6,–8), Z″(6,–16)
Answer:
X'' (-4, 8)
Y'' (-6, 8)
Z'' (-6, 16)
Step-by-step explanation:
The rule for reflecting across the y-axis is (x, y) -> (-x, y)
When you dilate by a scale factor of 2 about the origin, multiply each coordinate point by 2.
X (2, 4) -> (-2, 4) -> (-4, 8)
Y (3, 4) -> (-3, 4) -> (-6, 8)
Z ( 3, 8) -> (-3, 8) -> (-6, 16)

Answer:
36 ft
Step-by-step explanation:
The first step is to find the length of the hypotenuse of the newly formed right triangle. Using the Pythagorean theorem:
[tex]x=\sqrt{10^2+24^2}=\sqrt{100+576}=\sqrt{676}=26[/tex]
Adding this to the 10 foot tall part of the tree that remains standing, you get an initial height of 26+10=36 feet. Hope this helps!

2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it
1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.
Step-by-step explanation:
We are given the three expressions different from each other
We are supposed to find what may be same or different.
1) [tex](-2)^2[/tex]
[tex]\Rightarrow (-1)^2 \times (2)^2\\\Rightarrow -1 \times -1 \times 2 \times 2 \\\Rightarrow 4[/tex]
2)[tex]-2^2[/tex]
[tex]\Rightarrow -1 \times 2^2\\\Rightarrow -1 \times 2 \times 2 \\\Rightarrow -4[/tex]
3)[tex]-(2)^2[/tex]
[tex]\Rightarrow -1 \times (2)^2\\\Rightarrow -1 \times 2 \times 2 \\\Rightarrow -4[/tex]
Now 2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it
1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.

According to the water surface area rule, a fish tank can be
stocked with one inch of fish for each twelve square inches of
surface area. The fish that you are interested in putting in your
fish tank are each 2 inches. Your fish tank has a surface area of
576 square inches. According to the water surface area rule,
what is the maximum number of fish you can put in your tank?
Answer:
24 fishes
Step-by-step explanation:
If for 1 inch of fish corresponds 12 square inches of surface area, then for 2 inches correspond 24 square inches. Given that each fish is 2 inches, then for 1 fish 24 square inches of surface area is needed. To know how many fish you can put in your tank, we need to solve the following proportion:
1 fish / x fish = 24 square inches / 576 square inches
x = 576/24
x = 24 fishes
What is the probability that a single card chosen from a complete deck of cards is not an ace or a King? ( with explanation )
Answer:
84.6%
Step-by-step explanation:
There ae 52 cards in a standard deck there are 4 aces and 4 kings in each deck
therefore
52-8 =44, 44 cards that are not kings or aces
therefore the probability is
44/52 = 0.846153846*100 = 84.615%
There the chances are 44/52 or 84.6%
Answer:
11/13 or 84.62%
Step-by-step explanation:
There are 52 cards in a standard deck. There are 4 aces and 4 kings, 8 total. Subtract 8 from 52 to find the amount of cards that are not aces or kings:
52 - 8 = 44
Therefore, the probability of choosing a card that is not an ace or a king is 44/52, which can be simplified to 11/13. This can also be expressed as a percentage: approximately 84.62%.

A same side interior angle of two parallel lines is three times the other same side interior angle. Find the measures of these two angles.
Answer: The angles are 135° and 45°.
Step-by-step explanation:
In this situation, we have two parallel lines that are cut by another line, and the interior angles are the ones created in between the parallel lines and the third line.
If both angles are on the same side, then we must have that the sum of the angles adds up to 180°.
If the angles are A1 and A2 we have:
A1 + A2 = 180°
and, we also know that A1 = 3*A2, we can replace it in the previous equation and get:
3*A2 + A2 = 180°
4*A2 = 180°
A2 = 180°/4 = 45°
then A1 = 3*45° = 135°
The angles are 135° and 45°.

The figure below is made of two identical triangular prisms. What is the volume of the figure?
Answer:
300 in³
Step-by-step explanation:
The volume (V) of a triangular prism is
V = Al ( A is the area of the triangular face and l is the length )
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 5 and h = 6 , thus
A = [tex]\frac{1}{2}[/tex] × 5 × 6 = 15 in², so
V = 15 × 10 = 150 in³
Since the triangular prisms are identical, then volume of figure is
V = 2 × 150 in³ = 300 in³
