(Teaser) An angle that measures 6° is drawn on a piece of paper. You are looking at the angle through a×6 magnifying glass, whic
cluponka [151]

Answer:

No change in angle it will remain 6 degrees only.

Step-by-step explanation:

measurement of angle on paper = 6 degrees

power of magnifying glass = a*6

it means that the glass enlarges any thing seen through it by 6 times.

so if you are watching 1 cm object, it will be 1*6 times larger (i.e 6 cm) when seen through the magnifying glass.

It is to be noted that glass changes the size of the object, it does not change the shape of object. Th object will remain similar to the older one.

________________________________________________

Now given that

measurement of angle on paper = 6 degrees

This is a tricky question, here change of size of object is not being asked .

Since angle determines the shape of object , so angle will remain similar to as that on paper only size will get enlarged.

Hence, the measure of angle will remain same i.e 6 six degrees only. It will not change.

only thing will be that the shape of angle will appear larger but there will be no impact on angle.

Gary Oak is on a mission to complete his Pokedex before Ash Ketchum. To this end, he starts searching the tall grass for Pokemon
Vika [28.1K]

Let K_i denote the number of encounters required to see a new Pokemon after having encountered i-1 of them. Then K_1=1.

If Gary has already seen i-1 Pokemon, that leaves m-(i-1) still to be encountered, and the next new encounter has a probability of p_i=\frac{m-(i-1)}m of occurring. Then K_i is geometric, with PMF

P(K_i=k)=\begin{cases}(1-p_i)^{k-1}p_i&\text{for }k\ge1\\0&\text{otherwise}\end{cases}

Then the expectation and variance of K_i are

E[K_i]=\dfrac1{p_i}=\dfrac m{m-(i-1)}

V[K_i]=\dfrac{1-p_i}{{p_i}^2}=\dfrac{m(i-1)}{(m-(i-1))^2}

K is the total number of encounters needed to record all m Pokemon, so

K=\displaystyle\sum_{i=1}^mK_i

By linearity of expectation,

E[K]=\displaystyle\sum_{i=1}^mE[K_i]=\sum_{i=1}^m\frac m{m-(i-1)}=\frac mm+\frac m{m-1}+\frac m{m-2}+\cdots+\frac m1

E[K]=m\displaystyle\sum_{i=1}^m\frac1i

The K_i are independent, so the variance is

V[K]=\displaystyle\sum_{i=1}^mV[K_i]=\sum_{i=1}^m\frac{m(i-1)}{(m-(i-1))^2}

V[K]=m\displaystyle\sum_{i=0}^{m-1}\frac i{(m-i)^2}
