Which of the following examples would show a negative trend?
A. height and weight of students
B. test scores and height of students
C. outside temperature and heating bill
D. none of these
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.

Robots delivers goods in a factory. The sum of the maximum load of 3 robots (in kg) plus 120kg equals 220kg plus the max load of one robot.
What is the maximum load of a robot plus 1000kg?
Answer:
1050 kgStep-by-step explanation:
Let the maximum load of each robot is x.
Then we have the following equation:
3x + 120 = x + 2203x - x = 220 - 1202x = 100x = 50The maximum load of a robot is 50 kg:
50 + 1000 = 1050 kgGeet sells television He earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Geet sells 11 televisions with extended warranties, he earns $990. How much is the fixed amount Geet earns for each television?

Sherwin has twice as many stamps as his friends Allan and Gene combined. Allen has 55 stamps in his collection. Sherwin has 200 stamps in his collection.How many stamps does Gene have in his collection?
The equation 2 (x + 55) = 200 models this situation. which choice shows the sequence of operations needed to solve this problem, using both arithmetic and alegbra?
Answer:
gene would have 45
Step-by-step explanation:
if you take 55 and times that by 2 you get 110 then gene would need a toyal of 90 to complete the 200 so if you divide 90 by 2 you get 45
Answer:
C is correct
Step-by-step explanation:
You divide by 2 and that leaves x+55=100-55=45
You would finish with 45
Please help! I’m in 6th grade and I can’t remember how to do this
Answer:
2a + 4 + 7b
Step-by-step explanation:
ohh so to do this umm if you want it to be easier you can put a different symbols under the ones with the same variable. like a dot under 4a and - 2a, a square under .....
but if you want to do it without that, all you have to do is add them like numbers
you can also move them closer to each other. for example:
4a - 2a + 8 - 4 + 7b
4 - 2 is 2 so you just have to write 2a
2a + 8 - 4 + 7b
simplify
2a + 4 + 7b
since there are no other numbers with the variable b the equation above is the answer
The circumference of Tyler's bike tire is 72 inches.
What is the diameter of the tire? (Round to the nearest whole number.)
Answer:
23 inches
Step-by-step explanation:
Diameter: [tex]d=\frac{C}{\pi}[/tex]
[tex]d=\frac{C}{\pi} \\\\d=\frac{72}{3.14} \\\\d=22.929\\\\d=23[/tex]
Check your answer using the circumference of a circle: [tex]C=2*\pi*r[/tex]
Radius (r) = d/2. So 23/2 = 11.5
[tex]C=2*\pi*r\\\\C=2*3.14*11.5\\\\C=72.22\\\\C=72\ inches[/tex]
Hope this helps!

The top rectangle has a base b and a height h. The bottom rectangle has a base that is 1/3 of the length of the base of the top rectangle and a height that is 1/2 of the length of the height of the top rectangle. Devin writes the area of the smaller rectangle as the product 1/3b times 1/2h. Tracy rewrites this as 1/6bh. Which of the students’ expressions makes it easier to see how the areas of the rectangles are related? Explain.
Answer:
Tracy's explanation would be the simplest because 1\6 is half of one third she eliminated the need for an extra step if left the other way

Find the area of the shaded area! Show your work! (image attached)
Answer: 63 m
explanation: finding the area of the entire rectangle (so if the triangle wasn’t there) would be 13 x 6 which equals 78. Now we find the area of the triangle, so 6 x 5 = 30/2=15. Then you do 78-15, which equals 63. Hope this helped!

Answer:
Option D) (136-2a) + ( 3a + 39) = 180
Step-by-step explanation:
As per provided information .
XQR is a straight line So, sum of all angles formed on straight line is 180° .
This Means
∠XOM + ∠MOR = ∠XQR
On putting the given value we obtain
(136 - 2a) + (3a + 39) = 180
So, the required option is (D) (136 - 2a) + (3a + 39) = 180
You can solve it further to get the value of a .
It would help if you all could give me some guidance on this question. If you can help thank you very much :)

Hi! I hope you are enjoying your day!
Let's evaluate this expression for x.
We are given that
[tex]\bold{x=10}[/tex]
All we have to do in order to solve this expression is plug in the value of x.
[tex]\bold{x^2-2(x+5)}\\[/tex]
[tex]\bold{x^2-2x-10}[/tex]
Now, plug in the value of x:
[tex]\bold{10^2-2(10)-10}[/tex]
10² is equal to 100:
[tex]\bold{100-20-10}[/tex]
[tex]\bold{100-30}[/tex]
And that is equal to
[tex]\boxed{\boxed{\bold{70}}}[/tex]
Hope everything is clear.
If you have any questions, please comment.
