For two setsA and B, (A U B)' = A' n B'.
The statement that for two sets A and B, (A ∪ B)' = A' ∩ B' is true.
Let us check it with the help of an example.
Let A = {1,2,3,4,5,6} ,
B = {5,6,7,8,9,10} and ,
A universal set S = {1,2,3,4,....,15}
Now, we can write,
A ∪ B = {1,2,3,4,5,6,7,8,9,10}
LHS = (A ∪ B)' = {11,12,13,14,15}
A' = {7,8,9,10,11,12,13,14,15}
B' = {1,2,3,4,5,11,12,13,14,15}
RHS = A' ∩ B' = {7,8,9,10,11,12,13,14,15} ∩ {1,2,3,4,5,11,12,13,14,15} = {11,12,13,14,15}
As we can observe from above,
LHS = RHS
Hence, the statement that for two sets A and B, (A ∪ B)' = A' ∩ B' is true.

The graph of the derivative of a function, f, is shown. Use the graph to determine the interval on which f is increasing.
A. (-∞, 2)
B. (2, ∞)
C. (-∞, ∞)
D. (-1, ∞)
E. (-∞, 1)
Answer:
B) [tex](2,\infty)[/tex]
Step-by-step explanation:
Since we are given the graph of [tex]f'(x)[/tex], this gives us the value of the derivative, or the rate of change, of [tex]f(x)[/tex] given an x-value. For [tex]f(x)[/tex] to be increasing, then [tex]f'(x) > 0[/tex], which is a positive rate of change. As you may have noticed, when [tex]x > 2[/tex], the value of [tex]f'(x)[/tex] is positive. This means that f increases on the interval [tex](2,\infty)[/tex], or answer B.

in a residential neighborhood, the distribution of house valies is Unimodal and skewed to the right, with a median of $200,000 and an IQR of $100,000. for which of the following sample sizes is the sample median most likely to be above $250,000?A. n=10B. n=50C. n=100D. n=1000E. impossible to determine without more information
The smaller the sample size the greater the variability and higher the chance of getting an overestimate
From the given data
Median = $200,000
IQR = $100,000
The sample size for the median above to $250,000 is n =10
Because n=10 shows a sample with the fewest values, it is most likely that the sample median will be farther from the true median.

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. Write the polynomial in standard form. 3, 4+i
(Please answer soon as possible thank you)
By algebra properties, the standard form with rational coefficients is the polynomial x³ - 11 · x² + 7 · x + 51, whose lead coefficient is 1 and comprise the roots 3 and 4 + i.
How to determine a polynomial of least degree
A polynomials of least degrees includes all the roots and the given lead coefficient, which can used in the following formula:
p = a · Π (x - rₐ)
Where:
a - Lead coefficientrₐ - a-th root of the polynomial.If we know polynomial has rational coefficients, then the complex root 4 + i has a "twin" equal to 4 - i in accordance with the quadratic formula, otherwise the polynomial will have at least an irrational coefficient. Then, the least degree polynomial is introduced below:
p = 1 · (x - 3) · (x - 4 - i) · (x - 4 + i)
Then, we expand the expression by algebra properties:
p = (x - 3) · [x² - 8 · x - (16 - i²)]
p = (x - 3) · (x² - 8 · x - 17)
p = x³ - 8 · x² - 17 · x - 3 · x² + 24 · x + 51
p = x³ - 11 · x² + 7 · x + 51
The standard form is the polynomial p = x³ - 11 · x² + 7 · x + 51.

Using combinations, we concluded that the probability that fewer than 2 of the next 5 vehicles are from out of state is 0.907.
A checkpoint sees 75% of its traffic coming from within the state.
Therefore, there is a 0.75 percent chance that the car comes from the state.

A) There are two parallel lines and a line that goes through them in this diagram. The line that goes through them causes perpendicular lines to form.
What are perpendicular lines?
Perpendicular lines are lines that intersect and create 90° angles. The two angles in this diagram are 90° due to this intersection.
B) There are two types of angles: supplementary and complementary: complementary angles are angles whose measurements add up to 90°. Supplementary angles are angles whose measurements add up to 180°. As you can see in this problem, the two angles (7x+11 and -1+8x) are 90°. When added they would equal 180°. These angles are supplementary.
C) Now that you know what supplementary angles are, you can use its characteristics to solve for x:
Since the two angles added up equal 180, write an equation that represents this: (7x+11) + (-1+8x) = 180Now, combine like terms: 10 +15x= 180Subtract both sides by 10: 15x= 170Divide both sides by 15 and you have your answer: x= 11.33D) Now, solve for the two equations by plugging in x [you final answers should be 90]:
(7x+11) = 7(11.33) +11 = 90.31 ≈ 90(-1+8x) = -1 + 8(11.33) = 89.65 ≈ 90
For the function f(x)=x2−8x+11, find x when f(x)=−4.(Use a comma to separate multiple solutions.)

The length of a rectangular picture frame is 28 inches and its perimeter is 84 inches. What is the width of the picture frame? *
The perimeter of a rectangle can be calculated using the following formula:
[tex]P=2w+2l[/tex]Where
"w" represents the width of the rectangle
"l" represents the length of the rectangle
If you know the perimeter and length of a rectangle, you can use the formula to determine the width. The first step is to write the formula for the width:
-Pass 2l to the left side of the expression by applying the opposite operation to both sides of it:
[tex]P-2l=2w[/tex]-Divide both sides by 2
[tex]\begin{gathered} \frac{P-2l}{2}=\frac{2w}{2} \\ \frac{P-2l}{2}=w \end{gathered}[/tex]Now that we have determined a formula for w, replace the value of the length and perimeter and calculate the width:
P=84in
l=28in

Sidney has $85,450 in a savings account. The interest rate is 12% per year and is not
compounded. How much will she have in total in 1 year?
Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r
is the interest rate expressed as a decimal, and t is the time in years.
The amount that Sidney will have in her account in 1 year is $ 95,704.
Given that:-
Principal amount = $85,450
Interest Rate = 12 % per annum
i = prt
Where,
i represents interest,
p represents the principal,
r represents the interest rate, and
t represents the time (in years)
Hence, putting the values in the formula of simple interest, we get,
i = 85450*(12/100)*1 = $ 10,254

3x + 5y = 132
x = 2y
After solving the above two linear equations:
6y + 5y = 132
