True or false: For all subsets $ A $ and $ B $ of $ X $, if $ A \subseteq B $, then $ f[A] \subseteq f[B] $. I am trying to determine if the following is true or false: > For all subsets $ A $ and $ B $ of $ X $, if ...

Assume $A \subseteq B$. Let $y \in f(A)$. Then $\exists x \in A : f(x)=y$. But $A \subseteq B$, so if $x \in A$, then $x \in B$. Therefore, $\exists x \in B : f(x) = y$ so that $y \in f(B)$ as required. We conclude that $f(A) \subseteq f(B)$.

Stumped on a Bayes Theorem Question A certain medical syndrome is usually associated with two overlapping sets of symptoms, A and B. Suppose it is known that: P($A|B$) = 0.8 P($B|A$) = 0.9 P($B'|A'$) = 0.85 Find P...

We know that $$ P(A\mid B) = \frac{P(A \cap B)}{P(B)}, $$ and vice versa, so $$ P(A \cap B) = 0.8 P(B) = 0.9 P(A). $$ On the other hand, $$ P(B' \mid A') = \frac{P(A' \cap B')}{1-P(A)} = \frac{1-P(A \cup B)}{1-P(A)}, $$ and $P(A \cup B) = P(A)+P(B)-P(A \cap B)$ So $$ 1+P(A \cap B) -P(A)-P(B) = 0.85(...

That's not what it says: suppose that $d_X(x,y) < \delta$ for two arbitrary points of $X$. It might have been less confusing for you if the proof had said: "let $x,y$ be two arbitrary points of $X$ such that $d_X(x,y) < \delta$" instead: Reason: we want to show $$\forall x,y \in X: d_X(x,y) < \delta...

What is the minimal polynomial of $T^{-1}$? > Suppose $T$ is an invertible linear operator on a finite dimensional vector space with minimal polynomial $p_T=x^m+a_{m-1}x^{m-1}+...+a_1x+a_0$. Is it true that the minima...

Lemma: Given a non-constant polynomial $$ p(x) = x^m+a_{m-1}x^{m-1}+\ldots+a_0,\qquad a_0\neq 0$$ then $\xi\neq 0$ is a root of $p(x)$ iff $\frac{1}{\xi}$ is a root of the reciprocal polynomial $$ q(x) = a_0 x^m + a_1 x^{m-1} +\ldots + 1. $$ Proof: $p(\xi)=0$ implies $\frac{p(\xi)}{\xi^m} = q\left(\...

You have a good idea. But you need to define variables properly. Let $$ y=\log_{\frac{1}{3}}(3^{2x}) $$ Then $$ 3^{-y}=\left(\frac{1}{3}\right)^y = 3^{2x}. $$ The exponents in the previous equation must be the same (since the exponential function is injective). Thus $$ y=-2x. $$

How extensive is CD47? CD47 aka the "don't eat me" signal has recently been claimed to be expressed on all tumor cells. This doesn't seem to corroborate with other cell-biology experiments. On what other cells is CD47...

I don't know how extensive. Let's run a simple data query and find out: Go to GEO at NCBI. In the "Gene profiles" window, type CD47, and hit enter to launch the query. At the top of the resulting page, use the link labeled "Limits" to restrict the 7000+ results to human by entering the term "human" ...

Why is "nobody" called the "most privileged user after root"? When I was first learning Linux I recall reading that because it is so widely used, "nobody" is (jokingly?) known as the "second most privileged user, afte...

Sometime Linux distributions incorrectly implement the standards and assign files to the user nobody. In that case programs have access to a bunch of files which are not for them. According to the standards, the user nobody shouldn't own any files and it should only be used to run programs which don...

Knowing the distribution of $(X,Y)$ implies knowing the distribution of $(X,Y, X-Y)$? Consider a random vector $(X,Y)$ and suppose we know the joint probability distribution $P$ of $(X,Y)$. Does this mean that we...

If $f$ is the (continuous) mapping $(x,y)\to(x,y,x-y)$ from $\Bbb R^2$ to $\Bbb R^3$, then the joint distribution of $(X,Y,X-Y)$ is the probability measure $Q$ given by $Q(B)=P(f^{-1}(B))$, for Borel sets $B\subset\Bbb R^3$. This provides a rather abstract YES answer to your question. In your normal...

So you need $C\not=0$ such that $x^TCx = 0$ for all $x$. For $2\times2$-matrices this may be achieved with $C=C_2=\pmatrix{0&1\\\\-1&0}$. For $n>2$ you may use $\pmatrix{C_2&0\\\0&0}$.
