Answer:

   96°

Step-by-step explanation:

The measure of arc EC is twice the measure of ∠DEC, so is ...

  arc EC = 2×68° = 136°

The measure of arc BC is found from the sum of arcs around a circle.

  BC +CE +EB = 360° = BC +136° +128°

  BC = 96° . . . . . subtract 264°

The box plot is not symmetrical for either data set.

<h3>What is Quartile?</h3>

Quartiles divide the data values into four parts; the first quartile is the 25th percentile, the second quartile is the 50th percentile (also the median), and the third quartile is the 75th percentile.

Firstly, order the two data set from smallest to largest as shown in diagram below

The value of median, Q2 is the 5th value of both set

The value of Q1 and Q3 is the first and third quarter of the set

The range of data set one is 5-2=3 and of set two is 12-1=11

The interquartile range of set one is 5 - 2 = 3

The interquartile range of set two is 5 - 1.5 = 3.5

Thus, the box plot is not symmetrical for either data set.

Romashka-Z-Leto [24]

Answer:

There are 45 library books in the classroom.

Step-by-step explanation:

The problem says that Marvin, Latoya and Abdulla each read 3/7 of the library books in the classroom.  If Latoya read 3/7 of the books, we can form a proportion to determine the number of total library books in the classroom.  

\frac{3}{7} =\frac{15}{x}

To solve for 'x', we can either cross-multiply and divide, or we can multiply the denominator by the same factor as the numerator to get a product of 15.  In this case, the same factor would be 5, so 7 x 5 = 35.  If we cross-multiply:

3x = (15)(7) or x = 35.
