Identify each sequence as arithmetic or geometric. Explain your answer, and write an explicit formula for the
hammer [34]

Answer:

Arithmetic sequence

a_n=\frac{1}{2}-n for n\geq 1

Step-by-step explanation:

We are given that a sequence

-\frac{1}{2},-\frac{3}{2},-\frac{5}{2},-\frac{7}{2},...

We have to identify the sequence as arithmetic or geometric and write an explicit formula .

a_1=-\frac{1}{2}

a_2=-\frac{3}{2}

a_3=-\frac{5}{2}

a_4=-\frac{7}{2}

d_1=a_2-a_1=\frac{-3}{2}+\frac{1}{2}=-1

d_2=a_3-a_2=-\frac{5}{2}+\frac{3}{2}=-1

d_1=d_2=-1

When the difference of consecutive terms is constant then the sequence is an arithmetic.

Hence, the sequence is an arithmetic.

a_n=a+(n-1)d

a_n=-\frac{1}{2}+(n-1)(-1)=-\frac{1}{2}-n+1=\frac{1}{2}-n for n\geq 1

How many observations are there for each case in a t test for dependent samples?
Oxana [17]

The number of observations for each case in a t test for dependent samples is two is the correct answer.

In this question,

The dependent t-test also called the paired t-test or paired-samples t-test compares the means of two related groups to determine whether there is a statistically significant difference between these means. Each sample must be randomly selected from a normal population and each member of the first sample must be paired with a member of the second sample.

A dependent samples t-test uses two raw scores from each person to calculate difference scores and test for an average difference score that is equal to zero.

The groups contain either the same set of subjects or different subjects that the analysts have paired meaningfully. In dependent samples, subjects in one group do provide information about subjects in other groups.

Hence we c an conclude that the number of observations for each case in a t test for dependent samples is two is the correct answer.

The exact radius of a circle with a circumference 36 meters.
Lelechka [254]
Circumference = pi x diameter
So for this it is
36 = 3.14 x d (d = r x 2)
36 / 3.14 = 2r
11.46 = 2r
11.46 / 2 = r
5.73 = r
