Solve inequality.
-2 w<24
Answers
From the inequality given by -2w < 24, w is greater than -12.
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
Solving the inequality,
-2w < 24
Making sure the unknown variable is in one side and the constants in the other side.
-2w < 24
Divide both sides by -2, the coefficient beside the unknown variable,
(-2/-2)w < 24/-2
w < -12
Note that when we multiply or divide by a negative number
we must reverse the inequality.
w < -12 ⇒ w > -12
Therefore, w is greater than -12.

Answers
The coordinates of S are (-4,2) .
The sails' center of rotation = Origin (0,0)
Coordinates of S on the top of one of the sails, = (2,4)
Rotation :The action or process of rotating on or as if on an axis or center.
Centre of Rotation :The center of rotation is a point about which a plane figure rotates. This point does not move during the rotation.
It is given that sails have rotated 270° clockwise.
So, When we rotate a figure of 270 degree clockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.
So, the point turn (2, 4) into (-4, 2).
Thus, the coordinates of S are (-4,2).

The slope of the given function is not constant therefore it will not be a linear function so option (A) will be correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
Given the data table,
If we take its point as coordinate then (1,6),(6,27),(11,50)(13,56) and (16,70).
Slope associated with two points (1,6), (6,27)
(27 - 6)/(6 - 1) = 4.2
Now Slope is associated with two points(6,27),(11,50)
(50 - 27)/(11 - 6) = 4.6
Since the slope is not the same therefore given function is not the linear function because the linear function has a constant slope.
Hence "The slope of the given function is not constant therefore it will not be a linear function".

What is the shape of the distribution for the following set of data? x f 5 5 4 3 3 1 2 3 1 5
Answers
The shape of the distribution for the following set of data is: symmetrical.
What are distributions?When we study data, one of the major ways to understand it is to think about its general form, such as whether it is symmetrical, has more numbers on one side than the other, or fits a common probability distribution like the normal, binomial, or exponential.
Now,
By looking at how the data are arranged in the table, we can tell that the distribution's form is symmetrical. With 1 item at X=3, it appears that this occurs frequently. The average was calculated using the range of data from X=1 to X=5. In addition, the data contain 5 items at X=5 and X=1, respectively. Both of these occur equally often and at equal intervals from the average. We can also say that there are three items in the data at X=4, three things at X=2, and so on, all of which are equally far from the average. As a result, every piece of data is either averaged out or counterbalanced on the other side of the average. A symmetrical distribution is described here. Therefore, it is neither favorably nor negatively biased. Even though it is symmetrical, the distribution is not normal since a normal distribution contains more data at the average than at the tails, as opposed to fewer.Hence, The shape of the distribution for the following set of data is: symmetrical.

Answers
The population mean of the data is 6.
How to find the population mean?The population has n = 16 scores.
The sum of all of the scores is equal to 96.
Therefore, the population mean can be found as follows:
The population mean is the mean or average of all values in the given population.
The population mean is represented mathematically as follows:
population mean = sum of terms / number of terms
Therefore,
sum of terms = 96
number of terms = 16
Hence,
population mean = = 96 / 16
population mean = 6

if a circle passe though point (-4,2) and is tangent to the x-axis at (2,0), determine the coordinates of its center.
Answers
The centre is at (2, 10).
Step-by-step explanation:
(x - a)^2 + (y - b)^2 = r^2 is a circle with radius r and centre(a, b).
It passes through the points (-4, 2) and (2, 0), therefore:-
(-4 - a)^2 + (2 - b)^2 = r^2 and
(2 - a)^2 + (-b)^2 = r^2
Now the x coordinate (a) of the centre is 2 (because of the tangent at (2, 0)
So, the equations become:
6^2 + (2 - b)^2 = r^2
b^2 = r^2
--> 36 + (2 -b )^2 -b^2 = 0
--> 36 + 4 + b^2 - 4b - b^2 = 0
--> 4b = 40
--> b = 10.
So the centre is (2, 10).

The flat surfaces of a cube or cuboid, as well as the flat surfaces of paper, are all true examples of geometric planes, despite the fact that it is impossible to envision a plane in real life.A plane geometry is a closed, two-dimensional, or flat, figure.

The original price of the table set was $400.
What exactly is a discount?Customers are given discounts by shop owners in order to increase sales. A discount is a rebate or offer created to consumers on the listed price of goods.
A product's list price or marked price is the price proclaimed by the supplier or manufacturer, excluding any price reductions.The selling cost is the real price at which an article is sold after any reductions and discounts in the list price.Discounts are frequently described using words like "off" and "reduction."Now, as per the given question;
The paid price by Maria is $240 called selling price.
The total discount on the table set was 40%.
Let us consider the original price/marked price of the table set was 'x'.
Then the formula for calculating the original price/market price is;
Marked price - discount = selling price
x - 40%of x = 240
x - (40x)/100 = 240
100x - 40x = 24,000
60x = 24,000
x = 400
Therefore, the original price of the table set was $400.
