On a graph, points are scattered all over the graph.
Answers
The scatterplot that shows the strongest relationship between the variable x and the variable y is: “On a graph, points are grouped close together and decrease.” Hence, Option A is correct.
What is a scatter plot?In a scatterplot, dots are used to show the values of two different numerical variables. An individual data point's values are indicated by the placement of each dot on the horizontal and vertical axes.
An example of a plot or mathematical diagram is a scatterplot, which uses Cartesian coordinates to show the values of typically two variables given a collection of data.
Two quantitative variables assessed for the same individuals are shown in a scatterplot along with their relationship. The horizontal axis displays the values of one variable, and the vertical axis displays the values of the other variable.
Therefore, Option A is correct.

A 45 foot ladder is set against the side of a house so that it reaches up 27 feet. If Cooper grabs the ladder at its base and pulls it 4 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 23 ft.) Round to the nearest tenth of a foot.
Answers
Answer:
42 feets
Step-by-step explanation:
We consider the right-angle triangle with B being the right-angle:
AB = 24 ft ; AC = 45 ft
We can use the Pythagorean theorem:
[tex]AB^{2} = AB^{2} + BC^{2} \\45^{2} = 24^{2} + BC^{2} \\BC^{2} = 2025 - 576\\BC = \sqrt{1449} = 38[/tex]
The distance between the wall and the ladder is 38 feet.
Pulling the ladder away from the wall is adding 4 feet to the distance between the wall and the ladder.
38 + 4 = 42
The ladder is now 48 feet away from the wall at its bottom.

On a number line, what other number is the same distance from −2.8 as −7.2 is?
Answers
==================================================
Explanation:
Let's find the distance between the two given values
Let a = -2.8 and b = -7.2
Subtract a and b, then apply absolute value to ensure the result isn't negative.
|a-b| = |-2.8-(-7.2)|
|a-b| = |-2.8+7.2|
|a-b| = |4.4|
|a-b| = 4.4
The distance from -2.8 to -7.2 is 4.4 units.
To go from -2.8 to -7.2, we moved 4.4 units to the left.
Let's go back to -2.8 and now move 4.4 units to the right.
So we add 4.4 onto -2.8 getting
-2.8+4.4 = 1.6
The diagram is shown below.
On a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.
What is a number line?It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that two numbers on a number line that is:
-2.8 and -7.2
To find the other number that is the same distance from −2.8 as −7.2:
Mathematically, we can write a number expression:
= -2.8 -(-7.2)
= -2.8 + 7.2
= 4.4
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.
Accordingly, -7.2 is 4.4 units distant from -2.8.
= -2.8 +4.4
= 1.6
Thus, on a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.

What would be the perimeter of an image if a scale factor of 2.5 was applied?
Answers
Answer:
40 units
Step-by-step explanation:
So first if it was a scale factor of 2.5 you would multiply it by 2.5 for each side. So for the side of 3 you would multiply it by 2.5 which is 7.5 so that side and the other side across from it would be 7.5 units. Then for the next one there is 5 units so you do the same 5x2.5 is equal to 12.5 so will the one below it.
Then it would be (7.5 * 2) + (12.5 * 2)= 15+25+40
So then the perimeter would be 40 units.

A local food bank is creating Thanksgiving baskets. There are 72 cans of green beans, 96 cans of corn, and 48 cans of pumpkin. What is the greatest number of baskets that can be filled equally?
Answers
Answer:
24 baskets
Step-by-step explanation:
The GCF (greatest common factor) for 72, 96, and 48 is 24.
72/3 = 24
96/4 = 24
48/2 = 24
The greatest common factor of 72,96 and 48 is 24 so 24 baskets can be filled equally.
What is the highest common factor?The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.
For example in 6 and 12 6 is the highest common factor.
Given that,
There are 72 cans of green beans, 96 cans of corn, and 48 cans of pumpkin.
The number of baskets that can be filled equally will be a number which is the greatest multiple of all three 72,48 and 24.
The HCF of 72,48 and 24 = 24 because it is the only the highest number through which all numbers can be divisible.
Hence "The maximum or greatest number of baskets will be 24 such that all three cans will be filled equally".

Explanation
Formula is the first line. R is the radius with us 4 and h is the height which is 9. Substituting these values into the formula will get you pi times 4 squared times 9 divided by 3. When simplified this gets pi times 16 times 3. Using the approximate value of pi which is 3.14, multiple it with 16 and 3 will get you 150.72, round this to 150.8, which rounds to 151.

Answers
I found this very interesting!
Knowing the difference between the gain and the loss is essential to determine if a result is positive or negative, especially in commercial or economic operations.
Thus, the existence of a greater amount of negative elements than positive ones will imply a loss, with which it will not be recommended to carry out the activity given the high risk of loss.
In this way, a previous study of the conditions and probabilities of the operation can prevent losses and favor positive results.

Plastic, the wonder material that we use for everything and which pollutes our environment, is perhaps the most harmful of trash dumped by mariners and sea-goers in sea because it does not readily break down in nature. In-fact, the plastic that goes over the side today may still be around in hundreds of years to foul up the fishing gear, boat propellers, and beaches of future generations.
Careless disposal of plastic can have dire consequences. A plastic bag looks like a tasty jellyfish to an indiscriminate feeder like the sea turtle, but plastic is indigestible. It can choke, block the intestines of, or cause infection in those animals that consume it.
A plastic bag can also clog an outboard engine’s cooling system. Lost or discarded monofilament fishing line can foul propellers, destroying oil seals and lower units of engines, or it can become an entangling web for fish, seabirds, and marine mammals.
According to the Centre for Marine Conservation, over 25,000 pieces of fishing line were collected from U.S. beaches during the 1996 annual beach clean-up and at least 40% of all animal entanglements reported during the clean-ups involved fishing line.
Every day, more and more plastic is accumulating in our oceans. Recreational boaters are not the only group that improperly disposes off plastic refuse at sea. Plastics also enter the marine environment from sewage outfalls, merchant shipping, commercial fishing operations, and beachgoers.

The arithmetic mean of the given data set ( 12, 13, 23, 112 ) as a fraction in simplest form is 80/2.
What is Arithmetic mean?Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Given the sets;
12, 13, 23, 112
n = 4
First we add the numbers
12 + 13 + 23 + 112 = 160
Mean = Sum total of the number ÷ n
Mean = 160 ÷ 4
Mean = 80/2
Therefore the arithmetic mean of the given data set ( 12, 13, 23, 112 ) as a fraction in simplest form is 80/2.
