What is the closed linear form for this sequence given a1 = -15 and an + 1 = an - 8?
Elza [17]

Answer:

<h3>a_n=-8n-7 is the closed linear form of the given sequence.</h3>

Step-by-step explanation:

Given that a_1=-15 and a_{n+1}=a_n-8

<h3>To find the closed linear form for this given sequence :</h3>

So each of the successive term of the given sequence is decreases by 8

Therefore the common difference is -8

The given sequence is a arithmetic sequence.

The general form is a_n=a_1+(n-1)d

Substitute a_1=-15 and d=-8 in a_n=a_1+(n-1)d we get

a_n=-15+(n-1)(-8)

=-15-8n+8

a_n=-8n-7

<h3>Therefore a_n=-8n-7 is the closed linear form of the given sequence.</h3>

In the probability distribution to the​ right, the random variable x represents the number of hits a baseball player obtained in
Anna [14]

Answer:

a) This is a discrete probability distribution because between the sample spaces are all between 0 and 5 inclusive and the sum of probabilities is equal to 1.

Step-by-step explanation:

x ​p(x)

0 0.1663

1 0.3351

2 0.2869

3 0.1497

4 0.0387

5 0.0233

To show that it is a discrete probability distribution, Σ pᵢ = 1

That is, the sum of the individual probabilities for each sample space must equate to 1 at the end.

Σ pᵢ = 0.1663 + 0.3351 + 0.2869 + 0.1497 + 0.0387 + 0.0233 = 1.000

Hence, the probability distribution is indeed a discrete probability distribution.

Hope this Helps!!!
