Members of Alachua District Choir were asked, when given the choice between Romanticism or Gothic

zalisa [80]

Answer:

$\begin{array}{cccc}{} & {Romanticism} & {Gothic} & {Total} & {Males} & {48} & {63} & {111}& {Females} & {59} & {62} & {121} & {Total} & {107} & {125} & {232} \ \end{array}$

Step-by-step explanation:

Given

Romanticism

$Male = 48$

$Female = 59$

Gothic

$Male = 63$

$Female = 62$

Required

Complete the table <em>(See attachment for complete question)</em>

The table can be represented as:

$\begin{array}{cccc}{} & {Romanticism} & {Gothic} & {Total} & {Males} & {48} & {63} & {111}& {Females} & {59} & {62} & {121} & {Total} & {107} & {125} & {232} \ \end{array}$

The "total" column represents the number of males and female sampled, respectively.

$Male = 48 + 63 = 111$

$Female = 59 + 62 = 121$

The "total" row represents the number of Romanticism and Gothic sampled, respectively.

$Romanticism = 48 + 59 = 107$

$Gothic = 63 + 62 = 125$

The overall sample is calculated by adding up the number of males and females or the number of Romanticism and Gothic

$Overall = Male + Female$

$Overall = 111 + 121 = 232$

or

$Overall = Romanticism + Gothic$

$Overall = 107 + 125 = 232$

How do I solve for x??

Cloud [144]

The two angles given are vertical angles which mean they are the same.

x +40 = 60

Subtract 40 from both sides:

x = 20

A fish story: The mean length of one-year-old spotted flounder, in millimeters, is 127 with standard deviation of 22, and the me

pishuonlain [190]

Answer:

The z-score for this length is of 1.27.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

One-year-old flounder:

Mean of 127 with standard deviation of 22, which means that $\mu = 127, \sigma = 22$

Anna caught a one-year-old flounder that was 155 millimeters in length. What is the z-score for this length

This is Z when X = 155. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{155 - 127}{22}$

$Z = 1.27$

The z-score for this length is of 1.27.
