This is the concept of inequality;
We are told that the distance a car travels depends on how full gas tank is, this means that the car will travel until the point when gasoline is finished. Thus,
This mean that if the if the distance is given by the function f(x), x will be the gasoline since it is the dependent variable, liters this in other words can be written as (if the tank holds 89 ):

f(x)=distance(gasoline)<89

thus the correct answer will be:

B] Distance (amount of gasoline) <  89

How do you simplify a fraction?
attashe74 [19]
You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.

Benji wrote the expression below to match the description "three less than the quotient of a number and nine" he wrote “3-n/9”ex
bulgar [2K]
Benji’s error is that the division should happen BEFORE subtracting 3. 3 should be subtracted from the quotient.

The correct response should be: (n/9)-3

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}
