Answer:

discrete, the class boundaries are;

16 - 25

26 - 35

36 - 45

46 - 55

56 - 65

66 = 75

continuous, the class boundaries are;

16 to less than 26

26 to less than 36

36 to less than 46

46 to less than 56

56 to less than 66

66 to less than 76

Step-by-step explanation:

Given that;

Range of the dataset = maximum value - minimum value = 74 - 16 = 58

total number of data set n = 50

Rule : 2^{k} ≥ n

substitute value of n

2^{k} ≥ 50

k × log(2) = log( 50 )

k × 0.3010 = 1.69897

k = 1.69897 / 0.3010

k = 5.64

Hence, we have a total of 6 number of classes needed to be constructed.

so,

class width = 74 - 16 / 6 = 58 / 6 = 9.67

If the Data is discrete, the class boundaries are;

16 - 25

26 - 35

36 - 45

46 - 55

56 - 65

66 = 75

If the Data is continuous, the class boundaries are;

16 to less than 26

26 to less than 36

36 to less than 46

46 to less than 56

56 to less than 66

66 to less than 76

#1:

A)

you need to know where a vertex goes on a isosceles triangle...

I attached a picture that explains it.....

you also want to label triangle.... XYZ

I put a picture on of how you should of labeled the triangle...

B)

so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.

so your equations will need to be equal to 180.

4x+4+2x+2+7x-8=180

so we combine liked terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

now you want to check you answers so add them up to see if your answers equal 180...

60+30+90=180

to be continued.... i do second question on a second answer since i dont want pictures to get mixed up

Which statement best describes the association between variable X and variable Y? Question 1 options: perfect negative associati
polet [3.4K]
The statement which best describes the association between the variables X and Y is the <em>moderate positive association</em>. It is observable that the values of X and Y are increasing, however, not in a perfect manner as there are some minor deviations. But nonetheless, the direction is clear and the values are close to each other so they have a moderate positive association.
