Explanation:
A negative trend is when one variable goes up and the other variable goes down (or vice versa).
As the temperature goes down, the heating bill is likely to go up. This is of course assuming the person(s) use the heat to stay warm rather than just solely rely on something like coats/blankets/etc.
As the temperature goes back up, there's little to no need for heating. So the heating bill will likely go down.
As the name implies, negative trend graphs have negative slopes for the regression lines.

Example
A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
Try to solve the problem now.
The correct statistical question is,
''What are the speeds of the cars on the highway?''
Hence, Option B is true.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, By all the statements we get;
The statistical question is,
B. "What are the speeds of the cars on the highway?"
Since, it involves collecting data on a variable of interest (speed) from a group of individuals (cars on the highway).
Thus, Option B is true.

Heather was writing the decimal 0.12¯¯¯¯ as a fraction. She worked out the problem, but her fraction is not correct. Where did she make a mistake?
Equation 1: x = 0.12¯¯¯¯
Equation 2: 10x = 12.12¯¯¯¯
10x = 12.12¯¯¯¯
- x = 0.12¯¯¯¯
_______________
9x = 12
x = 12/9=4/3
Question 4 options:
She wrote equation 1 incorrectly.
She multiplied by the wrong power of 10 when setting up equation 2.
She subtracted the two equations incorrectly.
She simplified her fraction incorrectly.
Answer:
She multiplied by the wrong power of 10 when setting up equation 2.
Step-by-step explanation:
10*0.121212....=1.212121...., not 12.121212... because when multiplying by 10 you only need to shift the decimal to the right once, not twice.

Answer:
[tex]6cm:12cm[/tex]
Step-by-step explanation:
Okay so remember this you need to know model: actual. This is really, important to know when solving.
Model: Model dimensions Example: 1cm
Actual: Actual dimensions Example: 24ft
Graph A:
1. Count the boxes. remember that each box is 1cm. After you counted all sides of the graph you should've gotten 12cm by 6cm.
2. After you got your model dimensions your goal is to find the ACTUAL dimensions. By finding the actual dimensions Multiply 12(24) and 6(24) Note: you need to multiply your actual from your scale. Times your dimensions for each side.
3. After multiplying you should've got 288ft by 144ft this is your actual dimension for graph A.
Graph B:
1. Now your answer the problem is asking for also has to do with graph A. In order to do this process, you need to divide each dimension by width and length. [tex]\frac{288}{24}[/tex] this is your length [tex]\frac{144}{24}[/tex] this is your width. divide
2. you should've gotten 12 and 6. now make your numbers into a scale
6cm: 12cm

To find the decimal of 9/25, Tyler reasoned: “9/25 is equivalent to 18/50 and to 36/100, so the decimal of 9/25 is 0.36.”
Use long division to show that Tyler is correct.
Is the decimal of 18/50 also 0.36? Use long division to support your answer.
If its not too much can I have a explanation
Answer:
18/50 is also 0.36
Step-by-step explanation:
9/25, 18/50, and 36/100 are all the same number. They are just in different forms. 9/25 is the simplest form of 18/50 and 36/100. If you divide 36/100 by 9/25, you will get 4/4, which is 1, meaning that they are the same number. Same thing with 18/50. 18/50 divided by 9/25 is 2/2, which is 1, proving all of these numbers congruent.

Answer:
1372 cm^3
Step-by-step explanation:
To find the volume, you need to multiply height, length and width. In this question they are all given to us, so we just need to do the following:
volume = height*length*width
= 9 1/3cm*21cm*7cm (note that 9 1/3 could be simplified to 28/3)
= 1372 cm^3
We put ^3 at the end to show that it's a volume/3D.
I hope you can understand this :)
Answer: 1372
Step-by-step explanation:
Volume= length x width x height
Length= 21 cm
Width= 7 cm
Height= 9 1/3 cm
Multiply
21 x 7 x 9 1/3
147 x 9 1/3
* Note you can NEVER multiply mixed numbers like 9 1/3, so we have to make them improper.*
9 1/3 = 28/3
147 x 28/3= 4116/3
4116/3= 1372

(-9, 2)
(-4, -3)

(-4, 7)
Answer:
B(-4, -3)
explanation:
B' (-4, 2)
if it was translated up to 5 units, there has been change in y unit.in order to find its original point, we have to shift it 5 units below.→ B = (-4, 2 - 5)
→ B = (-4, -3)

Answer:
88/27
Step-by-step explanation:
Convert (2+(2/3)) into a improper fraction. To do this multiply the denominator (3) by the whole number (2) and add the numerator (2). (3*2)+2 = 8. Then put 8 over a denominator which is equal to the denominator of the mixed fraction. So (2+ (2/3) is 8/3) Do the same process with the other fraction.
Then multiply the numerators and denominators of the improper fractions:
(8/3)*(11/9) gives (88/27).

Circle A has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. The diameter of circle B is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle.
Part B: Use the formula for area and solve for the value of pi for each circle.
Part C: What observation can you make about the value of pi for circles A and B?
Answer:
A. The circumference is (pi)d where d is the diameter. So (pi) for circle A is 21.98/7=3.14 and for B is 18.84/6=3.14.
B. Area is (pi)r^2 where r=radius or d/2. So for circle A (pi)=38.465/(3.5)^2=3.14 and circle B (pi)=28.26/(3)^2=3.14.
C. To two places of decimals (pi) has a value of 3.14 in all cases. This indicates or implies that (pi) is a universal constant applying to all circles using the formulae.

Is the sum of 1/2 and 2/5 greater than 1?
Is the sum of 4/5 and 1/10 closer to 1/2 than to 1?
Answer:
no for both
Step-by-step explanation:
1/2 + 2/5=9/10
4/5 + 1/10= 9/10
Answer:
The first questions answer is No, because 1/2 converted to a fith is 2.5, so 2 fiths +2.5 fiths is 4.5 fiths vs 1 whole.
And to the second question the sum of 4/5 and 1/10 is closer to 1 than 1/2 because 1/10 + 8/10 ( which i turned 4/5 into a tenth) is 9/10 which is closer to One than 1/2

If on a scatter plot, there is a cluster of points that follow a certain trend, and one lone point far away that also follows that trend, is that lone point an outlier?
Answer:
yes!
Step-by-step explanation:
The point away from the cluster would be an outlier because it is away from the points that are together and it is just not a part of them so it would be an outlier.
HOPE THIS HELPED
Answer: Since most of the clustering algorithms have a minimum threshold of data points to form a cluster, the outliers are the lone data points that are not clustered.

Consider the function f(x)=x^2−7. What would be the new function g(x) if f(x) is translated left 2 units and down 3 units?
Answer:
g(x) = (x+2)² - 10
Step-by-step explanation:
Our current function is f(x) = x²-7
It is already shifted down 7 units from the parent function x², so we are just going to shift it down 3 more, making it shifted 10 units from x²
Next, we need to translate it 2 units to the left. We can simply do (x+2)² for this part
Final equation: g(x) = (x+2)² - 10
