Answer:

1.  35 boys and 28 girls

2.  42 long-sleeved shirts

3.  40 total outfits

Step-by-step explanation:

1.

Ratio of Boys to Girls is 5 is to 4, that means that there are "5" parts boys and "4" parts girls. So that makes:

5 + 4 = 9 parts in total

Total there are 63 kids, so each part would be:

63/9 = 7 kids per part

Now,

5 part are boys so 5 * 7 = <u>35 boys</u>

and

4 parts are girls so 4 * 7 = <u>28 girls</u>

<u></u>

2.

Long Sleeved Shirts = 60% of the total

Total is 70

So, we basically need 60% of 70

First, we want to convert 60% to decimal. We divide by 100, that's it! So:

60/100 = 0.6

Now to get the number we simply multiply the decimal of 60% we got, which is 0.6 with the total, which is 70. Thus,

0.6 * 70 = 42

Thus, there are <u>42 long-sleeved shirts</u>

<u></u>

3.

Lily has 30 dress, WHICH ARE 75% of the total outfits she has.

First of all, what is 75% in decimal?

We divide by 100:

75/100 = 0.75

We can now write:

30 is 0.75 times the total

Right?

Which number's 75% (or 0.75) is 30? This is what we need to figure out!

0.75 * which number would give us 30?

We have to simply divide 30 with 0.75 to get total number of outfits:

30/0.75 = <u>40 total outfits</u>

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}
