how do i solve a function even or odd
Answer:
You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

I just took the test
The difference of the polynomials given is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
Given are two polynomials are :
(-2x³y² + 4x²y3³ - 3xy⁴) and (6x⁴y - 5x²y³ - y⁵)
We need to subtract the polynomials and find the difference.
(-2x³y² + 4x²y3³ - 3xy⁴) - (6x⁴y - 5x²y³ - y⁵)
By multiplying the signs into the brackets
= -2x³y² + 4x²y3³ - 3xy⁴ - 6x⁴y + 5x²y³ + y⁵
Grouping the like terms, we get
= -2x³y² + (4x²y3³ + 5x²y³) - 3xy⁴ - 6x⁴y + y⁵
= -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
Therefore, the difference between the polynomials is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Write the Equation and show work. Find 'x', 'AC' and 'BC'
an equation you could use: AB+BC= AC
Answer:
[tex]BC=12\\x=6\\AC=24[/tex]
Step-by-step explanation:
Lines AB and BC have two smaller lines in them, meaning that they are of the same length. Thus, BC is 12.
AB + BC = AC
Substitute in values:
[tex]12+12=4x[/tex]
Add the numbers and swap sides:
[tex]4x=24[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4}=\frac{24}{4}[/tex]
[tex]x=6[/tex]
AC is [tex]4x=4\times6=24[/tex]

What is the chance of getting a sample
proportion of 70% or greater?
0
0.2
03
Answer:
The chance of getting a sample proportion of 70% or greater is 0.026.
Step-by-step explanation:
We are given that a poll shows that 50% of students play sports .
A random sample of 20 students showed that 70% of them play sports.
Let [tex]\hat p[/tex] = sample proportion of students who play sports
The z-score probability distribution for the sample proportion is given by;
Z = [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ~ N(0,1)
where, [tex]\hat p[/tex] = sample proportion of students who play sports = 70%
p = population proportion of students who play sports = 50%
n = sample of students = 20
Now, the chance of getting a sample proportion of 70% or greater is given by = P([tex]\hat p[/tex] [tex]\geq[/tex] 70%)
P([tex]\hat p[/tex] [tex]\geq[/tex] 70%) = P( [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] [tex]\geq[/tex] [tex]\frac{0.70-0.50}{\sqrt{\frac{0.70(1-0.70)}{20} } }[/tex] ) = P(Z [tex]\geq[/tex] 1.95) = 1 - P(Z < 1.95)
= 1 - 0.97441 = 0.026
The above probability is calculated by looking at the value of x = 1.95 in the z-table which has an area of 0.97441.
Hence, the chance of getting a sample proportion of 70% or greater is 0.026.

Your answer is probality B
Step-by-step explanation:
I LOOKED IT UP
A correct option is option (c).
The given point is (6,-3).
Reflection of the point:
When a point is reflected across the X-axis, the x-coordinates remain the same. But the Y-coordinates are transformed into their opposite signs.
Therefore, the reflection of the point (x, y) across the X-axis is (x, -y).
So, the reflection of the given point over the x-axis is,

Step-by-step explanation:
[tex]\frac{11}{12} - \frac{1}{6} q + \frac{5}{6} q - \frac{1}{3}[/tex]
first find the like terms
[tex]\frac{11}{12}- \frac{1}{3}[/tex]

To solve a system of 2 variables, only 2 equations are required. Choose the first two equations containing the variables in the system.
y = x − 1 2 x − 3 y = − 1
Subtract x from both sides of the equation.
y − x = − 1 2 x − 3 y = − 1
Reorder the polynomial.
− x + y = − 1 2 x − 3 y = − 1
Multiply each equation by the value that makes the coefficients of x opposite.
( 2 ) ⋅ ( − x + y ) = ( 2 ) ( − 1 ) 2 x − 3 y = − 1
Simplify.
− 2 x + 2 y = − 2 2 x − 3 y = − 1
Add the two equations together to eliminate x from the system.
− 2 x + 2 y = − 2 + 2 x − 3 y = − 1 − y = − 3
Multiply each term in − y = − 3 by − 1
y = 3
Substitute the value found for y into one of the original equations, then solve for x .
x = 4
The solution to the independent system of equations can be represented as a point.

The result can be shown in multiple forms.

The median is 120, The lower quartile is 112 and The upper quartile is 140
and interquartile range is 28.
What is interquartile range?The difference between the third and first quartiles is referred to as the interquartile range. Quartiles are the parceled values that partition the entire series into 4 equivalent parts. There are then three quartiles. The lower quartile is represented by Q1, the second quartile is represented by Q2, and the third quartile is represented by Q3, which is the upper quartile. As a result, the difference between the upper and lower quartiles constitutes the interquartile range.
Given data
115, 120, 118, 104, 109, 148, 135, 141, 139
arrange series in ascending order,
104, 109, 115, 118, 120, 135, 139, 141, 148
the middle term of series is 120
median = 120
for lower Quartile Q₁ = (109 + 115)/2 = 112
for upper Quartile Q₃ = (139 + 141)/2 = 140
interquartile range = Q₃ - Q₁ = 140 - 112 = 28
Hence the median = 120, lower quartile = 112, upper quartile = 140 and
interquartile range = 28.

In a small Library there are five non-fiction books for every nine fiction book there are 130 Non-fiction books how many fiction books are there
Answer:
For 130 non-fiction books, the number of fiction books can be from 270 to 278.
Step-by-step explanation:
Given that, there are 5 non-fiction books for every 9 fiction books.
Observe that, if the number of fiction books is less than 9, than there will be no no-fiction books.
So, there are 5 non-fiction books for every 9 to (9+8) fiction books
So, by elementary method, there will be 5n non-fiction books for every 9n+8 fiction books, where n is a natural number.
Or, if the number of non-fiction books is 5n, then the number of fiction books will be ranging from 9n to (9n+8).
For, 150 non-fiction books, 5n=150 or n=150/5=30.
Hence, the number of fiction books can be from 9n to (9n+8).
=9x30 to (9x30+8)
=270 to 278.
Hence, for 130 non-fiction books, the number of fiction books can be from 270 to 278.
