In one study, it was found that the correlation coefficient between two variables is -0.93.
Which statement is true?
A. There is a weak positive association between the variables.
B. There is a weak negative association between the variables.
C. There is a strong positive association between the variables.
D. There is a strong negative association between the variables.
the answer is d (i think) because anything aboveboard .90, whether it is positive or negative
Answer: D. There is a strong negative association between the variables.
Step-by-step explanation:
We know that when the value of the correlation coefficient lies between -1 to -.05 , then we say there is strong negative correlation between the variables.
OR
When the value of the correlation coefficient lies between 0.5 to 1, then we say there is strong positive correlation between the variables.
Given : In one study, it was found that the correlation coefficient between two variables is -0.93.
∵ -1< -0.93 <-0.5
Then , it indicates that there is a strong negative association between the variables.

The blueprint for landscaping a yard has a scale of 1/2" to 1 foot. If the bloeprint is a rectangle 18inches by 22 inches, what are the dimensions of the yard
Answer:
36x44 feet are the dimensions of the yard.
Step-by-step explanation:
Given that the blueprint for landscaping a yard has a scale of 1/2" to 1 foot.
i.e. scaling factor is 1/2 for one foot.
If real dimension is 1 foot, it is shown as 1/2 inch in blue print.
Using this we can find the real dimensions if given blue print dimensions.
The blueprint is a rectangle 18inches by 22 inches,
Hence real length of rectangle = 18(2) feet = 36 feet
Width of rectangle = 22(2) = 44 feet
i.e. the yard has dimensions as 36x44 feet.

What number represents the same amount as 33 3 3 hundreds ++ + plus 44 4 4 tens ++ + plus 1616 16 16 ones?
Answer: 3756
Step-by-step explanation:
33 x 100 = 3300
44 x 10 = 440
16 x 1 = 16
Total: 3756
The number represented by 33 hundreds plus 44 tens plus 16 ones is 3756, which is found by adding 3300 (33 times 100), 440 (44 times 10), and 16 (16 times 1) together.
The question involves adding numbers that compose a whole number through place values. In this case, we are looking at hundreds, tens, and ones. To solve this, we add up each group's contribution to the total. We have:
33 hundreds which is 33 * 100 or 330044 tens which is 44 * 10 or 44016 ones which is 16 * 1 or 16Adding these together:
3300 + 440 + 16 = 3756
So, 33 hundreds plus 44 tens plus 16 ones represents the number 3756.

4. The translation is considered an isometry or rigid motion. The figure's size, shape, area, etc has not changed. The only thing that changed is its position.
5. The rule stated means you shift the point 3 units to the right and 4 units up.
6. The rule would be (x,y) ---> (x-1, y-3) so we effectively subtract 1 from the x coordinate; subtract 3 from the y coordinate
7. Add 2 to the x coordinate to get x+2 = 2+2 = 4. Subtract 1 from they coordinate and we have 5-1 = 4. The point ends up at (4,4). Check out the attached image below.

[tex]\frac{5}{-1.6}<-3\frac{3}{10}-(-\frac{7}{20})<5\frac{6}{15} +(-2\frac{4}{5} )<-4.5*-2.3[/tex]
Step-by-step explanation:
In this case we have to calculate the value of each one of the terms and the organize it from the lowest to the highest, this is:
[tex]-3\frac{3}{10}-(-\frac{7}{20})=-2.59[/tex]
[tex]\frac{5}{-1.6} =-3.125[/tex]
[tex]5\frac{6}{15} +(-2\frac{4}{5} )=2.6[/tex]
[tex]-4.5*-2.3=10.35[/tex]
Now we can order the expressions, this is:

Kai is making a chessboard using pieces of wood that measure 1 square inch.
when he finishes, the chessboard will have an area of 64 square inches.
how many pieces of wood should he put along each side?
a.
64 pieces of wood
b.
642 pieces of wood
c.
8 pieces of wood
d.
82 pieces of wood
Answer:
The correct option will be: c. 8 pieces of wood.
Step-by-step explanation:
Suppose, the number of pieces of wood along each side of the chess board is [tex]x[/tex]
The area of each piece of wood is given as 1 square inch. So, the length of each piece of wood will be: [tex]\sqrt{1}= 1[/tex] inch.
And the total length of [tex]x[/tex] number of pieces of wood will be: [tex]1x[/tex] inches.
Given that, the area of the chess board is 64 square inches. So, the length of each side will be: [tex]\sqrt{64}=8[/tex] inches.
Thus, the equation will be.........
[tex]1x=8\\ \\ x=\frac{8}{1}=8[/tex]
So, he should put 8 pieces of wood along each side.
Answer: it will be 8
Step-by-step explanation: because 8×8=64
How many cubes are needed to build the base of this structure?
10 cubes for the base
Answer:
Option (D) 10 cubes
Step-by-step explanation:
The given structure is formed by assembling the cubes.
Number of cubes required for upper layer of the structure = 7 cubes
Now we have to find how many cubes will be required to form the lower layer of the structure.
From the structure ⇒
Cubes in lower layer = cubes in upper layer + 3 more cubes
= 7 + 3 = 10 cubes
Therefore, 10 cubes will be required to form the base of the structure.
Option (D) 10 cubes is the answer.
On six books shelves there are 72 books per shelf.How many books are there altogether? If 1/3 of these are non-fiction how many fictional books are there?
Given:
Total shelves: 6
Books per shelve: 72
Total books = ?
Solution:
Total books: 6 * 72 = 432
Total books = 432
Part 2:Given:
Fiction books = 1/3 of total books
Solution:
Nonfiction books = Total books - 1/3 of total books
= 432 - 1/3 * 432
= 432 - 166 = 266
Non- fiction books = 266

Find the width (w)of a rectangular room with a length (l) of 60 meters and an area (a) of 2,400 square meters
To find the area of a rectangular shape, we need to have the length and width of the shape.
Here the room is rectangular in shape.
The length of the room is 60 meters and lets say the width of the room is 'w' meters.
The area of room is given which is 2,400 square meters.
The area of rectangle is given by:
[tex]length \times width[/tex]
Now, plugging the values of the length and width, we get:
[tex]Area = 60 \times width[/tex]
[tex]2400= 60 \times width[/tex]
Solving for width, we get:
[tex]Width= \frac{2400}{60} =40[/tex] meters.
So, the width of the rectangular room is 40 meters.
Answer:The answer is

Solve by factoring 2x squared -6 = x squared+48
x = ± 3√6
2x² - 6 = x² + 48 ( subtract x² from both sides )
x² - 6 = 48 ( add 6 to both sides )
x² = 54 ( take the square root of both sides )
x = ± √54 = ± 3√6

Nyree divided 495 are 24 using partial quotients find the quotient and remainder explain your answer using numbers and words
Answer: Quotient=20 and remainder=15.
Step-by-step explanation:
Here dividend=495 and divisor=24
Step 1) Write easy multiples of 24 such as
24×2=48
24×5=120
24×10=240 and so on...
Step 2) Find the easier multiple of 24 to subtract from 495 .
Let 240 is the easiest one then 495-240=255 and note 10 as first partial quotient.
Step 3) Again subtracting 240 (as easier one) from 255 and note 10 as second partial quotient,we get 255-240=15 which is our remainder (as it is less than the divisor).
Step 4) add both the partial quotients=10+10=20→ Quotient
The quotient of 495 divided by 24 using partial quotients is 20, and the remainder is 15. This method simplifies the division by subtracting easily computable multiples of 24 from 495.
Nyree wants to divide 495 by 24 using partial quotients, a method where we break down a division problem into simpler pieces that we can solve in our head. For instance, knowing that 24 is close to 25, which is a quarter of 100, can help us simplify the problem. Let's start by subtracting multiples of 24 from 495 until we can subtract no more without going into negatives.
First, we know that 24 times 20 is 480, so we subtract 480 from 495, which gives us a partial quotient of 20 and a remainder of 15.Since 24 cannot go into 15, we stop here. Our total quotient, therefore, is 20 with a remainder of 15.The quotient of 495 divided by 24 is 20, and the remainder is 15. Partial quotients make it easier to handle large numbers by breaking them into smaller, more manageable pieces.

Assuming a regularly shaped rectangle, the formula for the area is given as:
A = L * W
where L and W are the length and width respectively
A = 3.6 x 10^2 miles * 2.8 x 10^2 miles
A = 100,800 square miles

At a college, 7 out of every 10 students worked either a full-time or part-time job in addition to their studies. If 4,900 students were enrolled at the college, how many students did not have a full-time or part-time job?
Remark
If 7/10 do have full or part time jobs then 3/10 do not.
That comes from 1 which represents all the students subtract 7/10 to get 3/10
Solution
Those without jobs = 4900 * 3/10 = 4900 *0.3 = 1470 that do not have any kind of job.
