If we use the 1.5 * IQR rule to determine whether there are any outliers, what is the right boundary?
Interquartile range:
Interquartile range is used by the data analyst to detect the whether there any data value which is located far away from others. The data analyst usually finds this by plotting the box-plot (a visualization technique based on interquartile range formula), Since it is the best and easy way to locate outlier values.
Answers
If we use the 1.5 * IQR rule to see if there are any outliers, the correct boundary is 43 days.
To use the 1.5 * IQR rule to determine whether there are any outliers in this data set, we need to first calculate the IQR. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1).
IQR = Q3 - Q1
= 28 - 18
= 10
Next, we can calculate the boundaries for potential outliers:
Lower boundary = Q1 - 1.5 * IQR
= 18 - 1.5 * 10
= 3
Upper boundary = Q3 + 1.5 * IQR
= 28 + 1.5 * 10
= 43
Since the maximum value in the data set is 56, there are no outliers above the upper boundary. Therefore, the right boundary is 43 days.

Answer:
25 fl oz
Step-by-step explanation:
1 pint is equivalent to 16 fl oz, so we're left with 25 fl oz and 16 fl oz. As you can see, 25 is greater than 16, making 25 fl oz the correct answer.
For two n by n square matricies A and B,
suppose rankA = rankB = n-1.
Can rank(AB) become less than n-1 ?
(e.g. rank (AB) = n-2)
If so, I humbly ask you for an example.
Thank you very much.
Answers
No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.
According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.
If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.
Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.
However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.
Therefore, if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

The sequence -1/5, 2/6, -3/7, 4/8How do I write a explicit equation for f(n) to represent the sequence.
Answers
So we must find an explicit equation for the sequence:
\(-\frac{1}{5},\frac{2}{6},-\frac{3}{7},\frac{4}{8}\)If you look carefully, you'll see that not only each term is a fraction bu also the top number in the fraction of the n-th term is n. For example, in the first term we have a 1, in the second a 2, in the third a 3 and so on. Not only that, the bottom number in each fraction is the terms postion plus 4. The first term has a 1+4=5, the second a 2+4=6, the third a 3+4=7 and so on. The only thing left is that terms in odd positions are negative and terms in even positions are positive. A way to achieve this is by using the term:
\((-1)^n\)If we merge all of this into one equation we get:
\(f(n)=(-1)^n\frac{n}{n+4}\)And that is the explicit equation we were looking for.

Answers
Answer:
f(x +h) = 4x² +4h² +8xh +5x +5h +3
(f(x+h) -f(x))/h = 4h +8x +5
f'(x) = 8x +5
Step-by-step explanation:
For f(x) = 4x² +5x +3, you want the simplified expression f(x+h), the difference quotient (f(x+h) -f(x))/h, and the value of that at h=0.
F(x+h)Put (x+h) where h is in the function, and simplify:
f(x+h) = 4(x+h)² +5(x+h) +3
= 4(x² +2xh +h²) +5x +5h +3
f(x +h) = 4x² +4h² +8xh +5x +5h +3
Difference quotientThe difference quotient is ...
(f(x+h) -f(x))/h = ((4x² +4h² +8xh +5x +5h +3) - (4x² +5x +3))/h
= (4h² +8xh +5h)/h
(f(x+h) -f(x))/h = 4h +8x +5
LimitWhen h=0, the value of this is ...
f'(x) = 4·0 +8x +5
f'(x) = 8x +5
__
Additional comment
Technically, the difference quotient is undefined at h=0, because h is in the denominator, and we cannot divide by 0. The limit as h→0 will be the value of the simplified rational expression that has h canceled from every term of the difference. This will always be the case for difference quotients for polynomial functions.

The 9th term of an arithmetic sequence is -5 and the 15th term is 31 find an expression for the nth term explicitly in term of n
Answers
The expression for the nth term is aₙ = 37+6n
What is an arithmetic sequence?An arithmetic sequence is a type of sequence in which the difference between the successive and preceding term is constant.
Given that, The 9th term of an arithmetic sequence is -5 and the 15th term is 31
The formula for nth term is given by;
aₙ = a+(n-1)xd
Where, a is the first term
n = number of terms
d = common difference
a₉ = a+(9-1)xd
a+8d = -5.......(i)
And
a₁₅ = a+(15-1)xd
a+14d = 31........(ii)
Solving the equation, we get,
d = 6
Putting, d = 6 in eq(i)
a+8x6 = -5
a = -5+48
a = 43
Now solving for nth term,
aₙ = 43+(n-1)x6
aₙ = 43+6n-6
aₙ = 37+6n
Hence, the nth term is (37+6n)

Write it in reduced form as a ratio of polynomials p(x)/q(x)
Answers
We are given the following expression
\(\frac{x^2}{x-5}-\frac{8}{x-2}\)Let us re-write the expression as a ratio of polynomials p(x)/q(x)
First of all, find the least common multiple (LCM) of the denominators.
The LCM of the denominators is given by
\((x-5)(x-2)\)Now, adjust the fractions based on the LCM
\(\begin{gathered} \frac{x^2}{x-5}\times\frac{(x-2)}{(x-2)}=\frac{x^2(x-2)}{(x-5)(x-2)} \\ \frac{8^{}}{x-2}\times\frac{(x-5)}{(x-5)}=\frac{8(x-5)}{(x-2)(x-5)} \end{gathered}\)So, the expression becomes
\(\frac{x^2(x-2)}{(x-5)(x-2)}-\frac{8(x-5)}{(x-2)(x-5)}\)Now, apply the fraction rule
\(\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}\)\(\frac{x^2(x-2)}{(x-5)(x-2)}-\frac{8(x-5)}{(x-2)(x-5)}=\frac{x^2(x-2)-8(x-5)}{(x-5)(x-2)}\)Finally, expand the products in the numerator
\(\frac{x^2(x-2)-8(x-5)}{(x-5)(x-2)}=\frac{x^3-2x^2-8x+40}{(x-5)(x-2)}\)Therefore, the given expression as a ratio of polynomials p(x)/q(x) is

What is translation?
A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.
Given that,
The translation is 1 units left and 5 units up.
The coordinates of the given figure are R(-3, -3), S(-3, -1), T(2, 0) and
U(1, -5).
Now, If the translation is 1 units left and 5 units up, then the coordinates become (x - 1, y + 5).
Hence, Coordinates for the image of the graph are;
R' = (-4 - 1, 2 + 5) = (-5, 7)
S' = (-3 - 1, -1 + 5) = (-4, 4)
T' = (2 - 1, 0 + 5) = (1, 5)
U' = (1 - 1, -5 + 5) = (0, 0)
Hence, The coordinates are R'(-4, 2), S'(-4, 4), T'(1, 5) and U' (0, 0).
Therefore, The figure with the coordinates R'(-4, 2), S'(-4, 4), T'(1, 5) and
