Which table shows positive correlation?​

Answer:

I'll clear the parentheses first. This is easy to do when adding, because there are no "minus" signs to take through any parentheticals. Then I'll group the like terms in accordance to their variables (keeping them in alphabetical order), and finally I'll simplify:

(2x + 5y) + (3x – 2y)

2x + 5y + 3x – 2y

2x + 3x + 5y – 2y

5x + 3y

These two terms are un-like (because they have different variables), so I cannot combine them. This means that I've gone as far as I can, so my hand-in answer is:

5x + 3y

Answer:

388 in²

Step-by-step explanation:

(10)(19) + (11)(18) = 388 in²

Answer:

388 in²

Step-by-step explanation:

The upper rectangle (the big one) is 30 in long and 10 in wide.  Thus, its area is the product of these two measurement:  300 in².

The lower rectangle is 8 by 11 inches, or 88 in²

The total area of the figure is 388 in²

Answer:

An example of complementary angles would be Angle FA and Angle EF

Step-by-step explanation:

These angles add up to 90 degrees

Hope this helps!

Answer:

∠AGF and ∠FGE, or ∠BGC and ∠CGD

Explanation

complementary angles are any angles which add up to 90°. since ∠AGB is a right angle according to the diagram, and AGD as well as BGE are straight lines (assumption), ∠DGE is also equivalent to 90° (opposite angles).

thus, the sum of ∠AGE and ∠BGD would be 90° each, so we know that ∠AGF and ∠FGE or ∠BGC and ∠CGD each add up to 90°.

Answer:

2.32

Step-by-step explanation:

Given the data:

3, 8, 1, 4, 7

The mean absolute deviation (MAD) :

Σ|x - m| / n

Mean, m = Σx / n

Σx = 23

n = 5

Mean, m = 23 / 5 = 4.6

|3 - 4.6| + |8 - 4.6| + |1 - 4.6| + |4 - 4.6| + |7 - 4.6|

(1.6 + 3.4 + 3.6 + 0.6 + 2.4) / 5

= 2.32

49 total dogs.

36 more small dogs.

13 big dogs.

lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.

the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.

Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.

F** k today's hw and their wording

Answer:

6.5 Large Dogs

42.5 Small Dogs

Step-by-step explanation:

You simply do not have enough love for dogs to solve the question.

Luckily I have an extremely high affection for dogs so I can help.

S = amount of small dogs

L = amount of large dogs

S + L = 49

S = 36 + L

plug the second equation into the correct variable of the first equation so:

(36+L) + L = 49

36 +2L = 49

2L = 49-36

L = 6.5      *this doesn't make sense*

S = 42.5    *this also doesn't make sense*

Answer:

QR ≈ 16.2 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan62° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{QR}{RP}[/tex] = [tex]\frac{QR}{8.6}[/tex] ( multiply both sides by 8.6 )

8.6 × tan62° = QR , then

QR ≈ 16.2 ft ( to the nearest tenth )

Answer:

152 cubic units

Step-by-step explanation:

Volume of a cube = L³ where;

L is the side length of a cube

For the cube of side length of 3 units

Volume of the cube = 3³

Volume of the cube = 27 cubic units

For the cube of side length of 5 units

Volume of the cube = 5³

Volume of the cube = 125 cubic units

Total volume the ice can make = (125 + 27)cubic units

Total volume the ice can make = 152 cubic units

Answer: y = -2x + 6

Slope-intercept form: y = mx + b, where m = slope and b = y-int

m = -2

(-1, 8) --> -1 = x₁, 8 = y₁

Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:

y - 8 = -2[x -(-1)]

y - 8 = -2(x + 1)

y - 8 = -2x - 2

y = -2x + 6

The volume is 180 in

Step-by-step explanation:

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container;

Answer:

The average of the sample means is 14.98.

As the number of surveys conducted increases, the average of the sample means approaches the population mean.

Step-by-step explanation:

Plato

The average of the sample mean from the given data values in the table is gotten as; 14.98

When finding the average, we need to sum up all the given data and then divide by the total number of data.

The given data values are; 15.09, 14.45, 14.91, 15.09, 14.91, 15.82, 14.36, 15.55, 14.36, 15.27.

The sum of these given data is;

15.09 + 14.45 + 14.91 + 15.09 + 14.91 + 15.82 + 14.36 + 15.55 + 14.36 + 15.27 =  149.81

Thus;

Average of sample mean = 149.81/10

Average = 14.98

Answer: well i have put things like leather and it shrunk while it was out in the sun

Step-by-step explanation:

We want to study how the Sun affects things on Earth, I will give you two examples.

First, we know that the Sun radiates electromagnetic energy.

So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.

The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).

Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.

So these are just two different examples of how the Sun affects things on Earth.
