PLZ HELP ME OUT How do I know a number is rational or irrational?
Answer: If a number is rational, it can be represented as a simple fraction, it can be written as a terminating decimal, and a repeating decimal.
If a number is irrational, it cannot be represented as a simple fraction, it cannot be written as a terminating decimal, and not as a repeating decimal. It never ends, never repeats, just like the constant pi.
Step-by-step explanation:
So if a number is rational, it can be represented as a simple fraction, it can be written as a terminating decimal, and a repeating decimal.
If a number is irrational, it cannot be represented as a simple fraction, it cannot be written as a terminating decimal, and not as a repeating decimal. It never ends, never repeats, just like the constant pi.

What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
A relation is a function if it has only One y-value for each x-value.
The given function is f(x) = –(x – 3)²(x + 2)
Function equal to minus x minus three whole square times of x plus two.
as x>3, the values of x will be positive.
So the additive inverse is positive, while the multiplicative inverse is negative.
Additive inverse simply means changing the sign of the number and adding it to the original number to get an answer equal to 0.
A multiplicative inverse or reciprocal for a number x, denoted by 1/x.
Hence, the additive inverse is positive, while the multiplicative inverse is negative.

A random sample of 13 hotels in Boston had an average nightly room rate of $172.10 with a sample standard deviation of $23.90. The approximate standard error of the mean for this sample is ________.
Answer:
6.63Step-by-step explanation:
Standard error of the mean is expressed as shown below.
SE = S/√n where;
S is the standard deviation
n is the sample suze
Given parameters
Standard deviation = $23.90
sample size = 13
Required
Standard error of the mean for this distribution.
Substituting the given value into the formula we have;
SE = 23.90/√13
SE = 23.90/3.6056
SE = 6.6286
Hence the approximate standard error of the mean for this sample is 6.63

______________Which transformations to the graph of j(x) would result in the graph of j(4x) – 27?
A) horizontal stretch by a factor of 4, and a translation 27 units right
B) horizontal stretch by a factor of 4, and a translation 27 units down
C) horizontal compression by a factor of 4, and a translation 27 units right
D)horizontal compression by a factor of , and a translation 27 units down
Answer:
Option D.
Step-by-step explanation:
It is given that, graph of j(x) transformed in the graph of j(4x) – 27.
We need to find the transformations.
Consider the new function is
[tex]f(x)=j(4x)-27[/tex] ... (1)
The translation is defined as
[tex]f(x)=j(kx+a)+b[/tex] ... (2)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph stretched horizontally by factor of 1/k and if k>1, then the graph compressed horizontally by factor of 1/k.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
k=4>1, the graph j(x) compressed horizontally by factor of 1/4.
a=0, so there is no horizontal shift.
b=-27<0, so the graph of j(x) shifts 27 units down.
So, the required transformations are horizontal compression by a factor of 1/4, and a translation 27 units down.
Therefore, the correct option is D.
Answer:
D) horizontal compression by a factor of 1/4, and a translation 27 units down

Use the round trip airfare table to determine the percentile rank of $1,133
Answer:
R= $1,133/100(7+1)
=234.86 RS.
Step-by-step explanation:
percentile rank is the percentage of scores that shall be equal to or less than a given value. The percentage falls within the range of 0 to 100. To find out the percentile rank, we used the formula:
R= P/100(N+1). Where R is the percentile rank, p is a percentile and N number of items.
Let for round trip airfare; the percentile is $1,133. And the number of days for the trip is 7.put these values in the formula, we have
R= $1,133/100(7+1)
=234.86 RS.
What are the x-intercepts of the graphed function?
O (-3,0) and (0, 1.5)
O (-3,0) and (1,0)
0 (-1,2) and (1,0)
O (0, 1.5) and (1,0)
Answer:
(-3,0) and (1,0)
Step-by-step explanation:
The x-intercepts of the function that is graphed above are the points where the line of the graph intercepts or crosses the y-axis. At that point, y is always 0.
Thus, the line of the graph intercepts the x-axis at x = -3, when y = 0 (-3, 0), and also at x = 1, when y = 0 (1, 0).
Therefore, the x-intercepts of the graphed function are (-3,0) and (1,0).

Find the missing vertex.(5.3): (-5,3): (-5.-1) *
Answer:
(5, -1)
Step-by-step explanation:
The three coordinates of a triangle are given as:
(5,3), (-5,3), (-5,-1).
To find:
The missing vertex = ?
Solution:
Let us label the vertices:
A (5,3),
B(-5,3),
C(-5,-1).
Let the missing vertex be ([tex]x, y[/tex]).
Let us recall the properties of a rectangle.
The opposite sides of the rectangle are equal and parallel to each other.
Let us consider the side AB, we can see that only x coordinate is changed from A to B.
Let us consider the side BC, we can see that only y coordinate is changed from B to C.
A and B are adjacent vertices.
Similarly the opposite vertices will be C and D.
Same pattern will be followed in CD as that of AB.
x coordinate will be changed by same difference as that of AB.
Change in x coordinate from D to C = [tex]-5-x[/tex]
Change in x coordinate from A to B = [tex]-5-5 =-10[/tex]
Equating them:
[tex]-5-x=-10\\\Rightarrow x = 5[/tex]
Same pattern is followed in BC and AD.
Their change in y coordinate will be same.
[tex]-1-3=y-3\\\Rightarrow y =-1[/tex]
Missing vertex is (5, -1).
Please refer to the attached image for the rectangle.
Write an inequality that represents "nine less than three times a number is greater than forty"?
Answer:
Three times a number is 3n. Nine less than that is 3n-9. This is NOT the same thing: 9-3n. Subtraction is not commutative. If n was 1, for example, 3(1)-9=-6. Looking at the other expression, 9-3(1)=6. 6 and -6 are definitely not the same number. So be careful how you set up your expression. Our inequality then would be

Which variable(s) in the data set are measured using a nominal scale? Environment Environment and Age Group Age Group None of the variables
Answer:
Environment
Step-by-step explanation:
Level of measurement used in statistics summarizes what statistical analysis that is possible. We have three types of level of measurement.
Nominal Scale
Ordinal Scale
Interval/ Ratio Scale
The nominal scale known as categorical or qualitative is the most basic level of measurement. Examples include numbers, colour, sex.
Ordinal are variables categorize according to hierarchy they usually have a meaningful order, but the intervals between the variables may not be equal.
In interval/ratio level of measurement, are measured and ordered. Examples are weight or size.
From the given question, it is only the environment that is measured using a nominal scale.
Age group is ordinal because it can be ordered based on hierarchy.
What are the full steps to 7x(x-2)+5(x-3)=-5
Answer:
[tex]x = -\frac{5}{7}, 2[/tex]
Step-by-step explanation:
To solve this equation, we need to simplify it down first. To do this, we must apply the distributive property to each term.
[tex]7x(x-2) + 5(x-3) = -5\\\\(7x^2 - 14x) + (5x - 15) = -5[/tex]
Now we can combine like terms.
[tex]7x^2 - 9x - 15 = -5[/tex]
Add 5 to both sides:
[tex]7x^2 -9x - 10 = 0[/tex]
We can see that this is a quadratic equation, in the form [tex]ax^2 + bx + c[/tex]. To solve for x, we must use the Quadratic Formula, which is [tex]\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex], where a is 7, b is -9, and c is -10.
Substitute inside the equation:
[tex]\frac{-(-9)\pm\sqrt{-9^2-4\cdot7\cdot-10}}{2\cdot7}\\\\\frac{9\pm\sqrt{81+280}}{14}\\\\\frac{9\pm19}{14}\\\\(9+ 19)\div14 = 2\\\\(9 - 19)\div14 = -\frac{5}{7}[/tex]
