Look at the following sequence. 128, 320, 800, 2000, . . . If it is a geometric sequence, choose the common ratio. If it is not
OlgaM077 [116]

Answer:

It is a geometric sequence en the common ratio is: r=\frac{5}{2}.

Step-by-step explanation:

1. By definition, a geometric sequence is a sequence in which you obtain a term by multiplying the previous one by a common ratio.

2. The common ratio is obtained by dividing a term by its preceding term.

3. Keeping this on mind, you have:

\frac{320}{128}=\frac{5}{2}\\

\frac{800}{320}=\frac{5}{2}

\frac{2000}{800}=\frac{5}{2}

4. As you can see, the common ratio is \frac{5}{2}

Korvikt [17]

Answer:

41.02 meters.

Step-by-step explanation:

See the attached diagram.

The distance between the goals of a soccer field is 52 meters. Each goal has a box that extends 5.49 meters into the field.

If the distance from the front of the box at one end of the field to the front of the box at the other end of the field is x meters, then we can write the equation as

5.49 + x + 5.49 = 52

⇒ x + 10.98 = 52

⇒ x = 41.02 meters. (Answer)

It is solved by multiplying 4 months x $20 = $80

Next, subtract (or add a negative) -$25.50 = $54.50

The null hypothesis in the Durbin-Watson test is always that there is a. negative autocorrelation. b. no autocorrelation. c. eit
Kamila [148]

Answer:

b. no autocorrelation.

Step-by-step explanation:

The Durbin-Watson test assumes that

H0:ρ=0

HA:ρ≠0

p=0 is a statement for the null hypothesis that assumes that the error term in one period is not correlated to the error term in the previous period.

The Durbin-Watson test is used in regression analysis to test for autocorrelation. The results from the test would always range from 0 to 4. A value of less than 2.0 indicates positive autocorrelation. A value of 2.0 indicates no autocorrelation, and a value of 2.0 to 4.0 indicates negative autocorrelation.
