Which represent geometric sequences? Check all that apply.

Anon25 [30]

The sequence that represents a geometric sequence can be seen in the 1st option and the 4th option in the image attached.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a set of integers that follows a pattern in which the following term is determined by multiplying the previous one by a factor known as the common ratio (r).

$\mathbf{a_n = a_{n-1}\times r}$ or $\mathbf{a_n = a_{1}\times r^{n-1}}$

$\mathbf{a_2 = a_{2-1}\times r}$

$\mathbf{a_2 = a_{1}\times r}$

$\mathbf{ r= \dfrac{a_2}{a_1}}$

From the options given, the options that have geometric sequences are:

3/16, 3/8, 3/4, 3/2

r = (3/8)/(3/16) = (3/4)/(3/8) = 2 (proves that it is a geometric sequence)

3, 9, 27, 81
r = 9/3 = 27/9 = 3 (proves that it is a geometric sequence)

Randy has two 28-pound blocks of ice for his snow cone stand. 1). How many pounds of ice does randy have at his snow cone stand?

dalvyx [7]

Randy has 56 pound blocks of ice for his snow cone stand

Tons of ice is 0.028 tons or $\frac{7}{250} \text{ tons }$

Solution:

Randy has two 28-pound blocks of ice for his snow cone stand

1). How many pounds of ice does randy have at his snow cone stand?

Calculate the total pounds that Randy has

Total pounds = 2 x 28 = 56

Thus Randy has 56 pound blocks of ice for his snow cone stand

2) How many tons of ice is there?

Total pounds of ice = 56 pounds

So we have to convert 56 pounds to tons

Use the conversion factor

1 pound = 0.0005 ton

Therefore, 56 pounds is equal to,

56 pound = 0.0005 x 56 tons = 0.028 tons

Thus in decimal we got, 0.028 tons

Convert to fraction form,

$0.028 = \frac{0.028}{1000} \times 1000 = \frac{28}{1000} = \frac{7}{250}$

Thus tons of ice is 0.028 tons or $\frac{7}{250} \text{ tons }$

A standardized variable always has a mean of _______ and a standard deviation of _______. b. The z-score corresponding to an

Feliz [49]

Answer:

Step-by-step explanation:

We know that normal distribution as special characteristics such as symmetry, unimodal, no skewness, mean =median=mode, etc

A standardized variable for normal variable X is

$Z = \frac{x-\mu}{\sigma}$ will be normal with mean =0 and sigma =1

The probability will be divided equally on either side of the mean =0 i.e. y axis

Hence the answers would be

A standardized variable always has a mean of __0_____ and a standard deviation of ___1____. b. The z-score corresponding to an observed value of a variable tells you ____the std normal score.___. c. A positive z-score indicates that the observation is __to the right ____ the mean, whereas a negative z-score indicates that the observation is __to the left_____ the mean
