Step-by-step explanation:

$m(arc AD) = m \angle ARD \\ = 105°\\\\m(arc BD) = m \angle BRD \\ = 50°+ 35° \\ = 85°\\\\m(arc ADB) = 105°+50°+ 35° \\ = 190°\\\\m(arc ABC) = 360°-(105°+50°) \\ = 360°-155° \\ = 205°\\\\ \\$

Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7

The distribution of certain test scores is a nonstandard normal distribution with a mean of 50 and a standard deviation of 6. Wh

love history [14]

Answer:

Mean value is 0 and standard deviation is 1 after all test scores have been standardized by converting them to z-scores using z

Step-by-step explanation:

In a standard normal distribution (also called as Gaussian distribution) all values of the sample can be projected to a normal distribution with mean 0 and standard deviation 1 using their z-scores.

z-score of a value X can be calculated as follows:

z= $\frac{X-50}{6}$ where

50 is the mean of the test scores
6 is the standard deviation of test scores

A ratio scale contains _____. the properties of order, classification, and equal distance between points but no unique origin th

Verdich [7]

Answer:

the properties of classification, order, equal distance, and unique origin.

Step-by-step explanation:

A level of measurement refers to a classification which is used to illustrate the attributes of the values assigned to variables. Basically, there are four (4) levels of measurement for a variable and these are;

1. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

2. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

3. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

4. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

Hence, a ratio scale contains the properties of classification, order, equal distance, and unique origin.
