The integer +3 describes the statement, 3 inches above average.
What is an average?
A single number chosen to represent a group of numbers is called an average, and it is typically calculated by dividing the total number of numbers in the group by the number of numbers in the group. As an illustration, the sum of the integers 2, 3, 4, 7, and 9 is 5.
One point in the average refers to the amount of 1 inch.
If the average is above 3 inches, it means that the value of the average is above 3 inches. It further implies that the total value has gained 3 inches on that average.
Inches mainly describe the gains and losses in short-time investments. A positive sign (+) shows the above average, and a negative sign (-) represents the below average.
Therefore, the integer +3 describes the statement, 3 inches above average.

Does the compound event consist of two mutually exclusive events?
Two dice are rolled. The sum of the dice is a 3 or a 9.
Probability = number of desired event occurrences/number of events in sample space = 9/36 = 1/4
What is meant by probability?Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely it is that a claim is true. The probability of an event is a number between 0 and 1, with 0 signifying impossibility and 1 expressing certainty.
A compound event is made up of two separate events.
Here is a table of probable sums of two die rolls. Die 1 and Die 2 values are listed along the side and top. The figures are roughly near the middle. The sum of Die 1 = 2 and Die 2 = 2 is 4, for example.
Die 2
Die1 1 2 3 4 5 6
1 2 3 4 5 6 7
2 3 4 5 6 7 8

4 5 6 7 8 9 10
5 6 7 8 9 10 11
6 7 8 9 10 11 12
Rolling two dice yields 6 * 6 = 36 possible outcomes, or 36 possible sums. There are 36 occurrences in the sample space.
Looking at the table, a 3 or a 9 happens as the sum 9 times, resulting in 9 of the 36 potential occurrences having a sum of 3 or 9.
Probability = number of desired event occurrences/number of events in sample space = 9/36 = 1/4

Larry's tuition for last semester was $5510. If he paid $6080 this semester, his tuition increased by
% (round to the nearest tenth of a percent).
His tuition was increased by 10.34%
What is meant by percentage?A quantity or ratio stated as a fraction of 100 is known as a % in mathematics (from the Latin per centum, "by a hundred").
The Latin word per centum, which means "hundred" or "by the hundred," is the source of the word "percent." The Italian phrase per cento, which means "for a hundred," gradually shrank to become the symbol for "percent," which is now used globally. It finally vanished totally. The word "per" was frequently shortened to "p." Two circles and a horizontal line made up the "cento," which is how the contemporary "%" symbol is now represented.
Given, Larry's tuition for last semester was $5510
% increase= (6080-5510)/5510

What is the slope-intercept form of the equation of the line shown in the graph?
The equation in slope intercept form is y= (-3/4)x + 95.
What is Linear Function?An equation can be represented by a linear function. The standard form for the linear equation is:
y= mx+b , for example, y=x+4.
Where: m= the slope.
It can be calculated for Δy/Δx.b= the constant term that represents the y-intercept. For the given example: m=1 and b=4.
It is important to inform that the standard form for the linear equation can be called slope-intercept form.
For writing a linear equation, you need two points. From the given graph, it is possible to extract some points, such as: (20,80), (60,50). Then, you should replace the known points in the slope-intercept form (y=mx+b).
For the point (20,80), you can write 80=m*20+b. And for the point (60,50), you can write 50=m*60+b.
Thus, you have:80=20m+b (1)50= 60m +b (2)For solving the previous system, you have to multiply the equation 1 by -1.
Thus,-80=-20m-b (1)50= 60m +b (2)
After that, sum equations 1 and 2.-80+50 = -20m+60m-30=40mm=-30/40m=-3/4
Now, you have y= (-3/4)* x+b.
For finding coefficient b, you should use one of the given points. For example:
(20,80).
y= (-3/4)*x+b for (20,80)80
= -3/4*(20) +b 80
= - 60/4+bb=80 + 60/4b=(320+60)/4b=380/4b
=95
Therefore, the equation in slope intercept form is y= (-3/4)*x + 95.

When point F
is reflected in the line y = x, the image is located at F"(-7, 1).
The coordinates of F' when reflected in the line y=x is F'(1,-7)
Given:
When point F is reflected in the line y = x, the image is located at F"(-7, 1).
The x-coordinate and y-coordinate are reversed when a point is reflected over the line y = x. The x-coordinate and the y-coordinate switch places and become negated if you reflect over the line y = -x (the signs are changed). The point is on the line y = x. (y, x).

What is the value of X? x(x² - 3x - 40) = 0
please show me how u solve it
Answer: x = 0, 8, -5
Step-by-step explanation:
We are trying to solve what value we substitute x into to get the value of 0. We have x outside of (x² - 3x - 40), and we can set that equal to 0. That will be one value of x because we are still left with (x² - 3x - 40). To solve this, we can factor it out into (x-8)(x+5). Set each equal to 0, (x-8) = 0 which leaves us with x = 8, and (x+5) =0, which leaves us with x = -5.

The perimeter of an ICU ward, that is rectangular in shape, is 258 feet. The width is 37 feet less than the length. Find the dimensions of this ward.
Find Length(ft) and Width(ft)
The dimensions of the rectangle is 83 feet x 46 feet
What is the Perimeter of a Rectangle?
The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P = 2 ( Length + Width )
Given data ,
The perimeter P of the rectangle = 258 feet
Let the length of the rectangle be = L
Let the width of the rectangle be = W
And , The width is 37 feet less than the length. ,
So , W = L - 37
Perimeter P = 2 ( Length + Width )
Substituting the values of L and W in the equation , we get
Perimeter P = 2 ( L + L - 37 )
2 ( L + L - 37 ) = 258
( L + L - 37 ) = 129
2L - 37 = 129
Adding 37 on both sides , we get
2L = 166
Divide by 2 on both sides , we get
Length L of the rectangle = 83 feet
Substituting the value of L in equation ,we get
W = L - 37
Width W of the rectangle = 46 feet
Therefore , Length = 83 feet and Width = 46 feet
Hence , the dimensions of the rectangle is 83 feet x 46 feet

C. 5x-2y=34
D. 2x+5y=2
E. y+2=-2/5(x-6)
F. y+2=5/2(x-6)
y + 2 = 5/2 (x - 6) ; 5x-2y=34 ; y=5/2x-17 is the equations of the line that goes through the point (6,-2) and is perpendicular to the line y+2=-2/5(x-10), Hence the correct options are B, C and F.
What is equation of the line?The standard forms of the equation of a line are:
Slope-intercept form:
y = mx + c
Where m indicates the slope of the line and c is the y-intercept
Intercept form:
x/a + y/b = 1
General form of the equation of the straight line, i.e. Ax+By+C = 0
x/(-C/A) + y/(-C/B) = 1
where a = -C/A and b = – C/B
Normal form:
The equation of the line whose length of the normal from the origin is p and the angle made by the normal with the positive x-axis is given by α is given by:
x cos α+y sin α = p
Given,
Point = (6,-2) = (x2,y2)
Equation of line = y+2=-2/5(x-10)
General equation of the line = y - y1 = m ( x-x1 )
After comparing we get,
Slope of the given line = -2/5
As we know both the lines are perpendicular to each other so, product of their slopes must be equal to -1.
m1 × m2 = -1
-2/5 × m2 = -1
We get m2 = 5/2
So the equation of the line having slope 5/2 and passing through (6,-2) is:
y - y2 = m2 ( x-x2 )
y -(-2) = 5/2 (x - 6)
y + 2 = 5/2 (x - 6)
Hence, we get equation of the line as y + 2 = 5/2 (x - 6) .

12.96 +7.29 = 20.25 . . . . . true
Segment XY is a tangent.
Secant relationIf segment YZ is extended across the circle, the lengths of the segments from Y to the circle intersection points are 1.8 and (1.8 +2·2.7) = 7.2. The relation between the secant and the "tangent" will be ...
3.6² = (1.8)(7.2) . . . . . true
This means XY is a tangent.
