What expression shows the relationship between the value of any term and n, its position in the sequence for the given sequence?

Mathematics
1 answer:
Sedaia [141]3 years ago
8 0

Answer:

B

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

a_{n} = a_{1} + (n - 1)d

where d is the common difference and a_{1} the first term

here d = - 10 - (- 5) = - 5 - 0 = 0 - 5 = - 5 and a_{1} = 10, hence

a_{n} = 10 - 5(n - 1) = 10 - 5n + 5 = 15 - 5n → B

Is it true w is the set of (s,w,n,t,c)
umka21 [38]

Answer:

{w} is the SUBSET of   {s,w,n,t,c}

Step-by-step explanation:

SUBSET: Any set  P is called a SUBSET of a set Q is ALL ELEMENTS of P are in the set Q.

i.e P ⊂ Q

Here, the given set  Q  =  {s,w,n,t,c}

Also, set P = {w}

Now,as the element w of set P is also an element of set Q.

⇒ P is the SUBSET of  Q

⇒ P ⊂ Q

⇒  {w} ⊂  {s,w,n,t,c}

Hence,   {w} is the SUBSET of   {s,w,n,t,c}.

What is the answer to 13 in precise detail?
lyudmila [28]

Well, I don't know.  Let's see . . . . .

First draw: One 'M' available out of 11 letters.   Probability of picking it = 1/11.
2nd draw:  Four 'I's available out of 10 letters.  Probability of picking one = 4/10.
3rd draw:  Four 'S's available out of 9 letters.   Probability of picking one = 4/9.
4th draw:  Three 'S's available out of 8 letters. Probability of picking one = 3/8.
5th draw:  Three 'I's available out of 7 letters.  Probability of picking one = 3/7.
6th draw:  Two 'S's available out of 6 letters.   Probability of picking one = 2/6.
7th draw:  One 'S' available out of 5 letters.     Probability of picking it = 1/5.
8th draw:  Two 'I's available out of 4 letters.     Probability of picking it = 2/4.
9th draw:  Two 'P's available out of 3 letters.   Probability of picking one = 2/3.
10th draw: One 'P' available out of 2 letters.   Probability of picking it = 1/2.
11th draw: One letter left.  It is an 'I'.  Probability of picking it = 1 .

Probability of all of those draws in order =

    (1/11) x (4/10) x (4/9) x (3/8) x (3/7) x (2/6) x (1/5) x (2/4) x (2/3) x (1/2) x (1) =

           1,152 / 39,916,800 =

                 1 / 34,650 =

                                     0.00002886 =

                                   <em>  0.002886 percent</em> (rounded)

Not a good bet.  (But better than the lottery.)
