(a) How is the number e defined? e is the number such that lim h → 0 e−h − 1 h = 1. e is the number such that lim h → 0 eh − 1 h

Fed [463]

Answer:

is the number such that lim h → [infinity] eh + 1 h = 1.

Step-by-step explanation:

The number e is known as the Euler's constant or Euler's number. The number basically is a mathematical expression that is equal to the rational number 2.71828. In addition, it is also the base of the natural logarithm or the Naperian logarithms. It is the number that the natural logarithm is equal to one. In addition, it is the limit of :

$\lim_{n \to \infty} (1 + \frac{1}{n })^{n}$

as n approaches infinity.

The expression is calculated as a sum of the infinite series

e = $\frac{1}{1!} = \frac{1}{1} + \frac{1}{1} + \frac{1}{1*2} + \frac{1}{1*2*3}+ ...$

Let be the set of permutations of whose first term is a prime. If we choose a permutation at random from , what is the probabili

Dennis_Churaev [7]

Answer:

$Pr = \frac{1}{6}$

Step-by-step explanation:

Given

$S = \{1,2,3,4,5\}$

$n = 5$

Required

Probability the third term is 3

First, we calculate the possible set.

The first must be prime (i.e. 2, 3 and 5) --- 3 numbers

$2nd \to 4\ numbers$

$3rd \to 3\ numbers$

$4th \to 2\ numbers$

$5th \to 1\ number$

So, the number of set is:

$S = 3 * 4 * 3 * 2 * 1$

$S = 72$

Next, the number of sets if the third term must be 2

$1st \to 2$ i.e. 1 or 5

$2nd \to 3\ numbers$ ---- i.e. remove the already selected first term and the 3rd the compulsory third term

$3rd \to 1\ number$ i.e. the digit 2

$4th \to 2\ numbers$

$5th \to 1\ number$

So

$r = 2 * 3 * 1 * 2 * 1$

$r = 12$

So, the probability is:

$Pr = \frac{r}{S}$

$Pr = \frac{12}{72}$

$Pr = \frac{1}{6}$

You need at least $40 to buy some notebooks, but your parents don’t want to give you more than $50. Write an inequality represen

Bad White [126]

m = amount of money you receive

You need at least $40, so that means you need m = 40 or more

So $m \ge 40$ which is the same as saying $40 \le m$ . You flip both sides and also flip the inequality sign as well.

At the same time, your parents won't give you more than $50. So the largest m can get is m = 50. This means $m \le 50$

-----------------

Combine $40 \le m$ and $m \le 50$ to get the compound inequality $40 \le m \le 50$

This represents all the possible values of m. We see that m can get as small as m = 40, or as large as m = 50, or anything in between.

------------------

Answer: $40 \le m \le 50$
