Answer is attached

Step-by-step explanation:

6.11

Marginal Distribution of Marital Status

Single 4.1%

Married 93.9%

Divorced 1.5%

Widowed .5%

Marginal Distribution of Job Grade

Job Grade 1 11.6%

Job Grade 2 51.5%

Job Grade 3 30.2%

Job Grade 4 6.7%

Each of the marginal distributions sum up to exactly 100%. Depending on how one rounds the percentages, it is possible that the results will not be exactly 100%.

Find the distance between the points (1, 5) and (1, -4). 3 √(41) 9
8_murik_8 [283]

Answer:

The distance between the givens points is 9 unit

Step-by-step explanation:

Given points are as :

A = ( 1 , 5 )

B = ( 1 , - 4 )

So, The Distance between points A and B = AB

Now, From Distance formula

AB = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}

Or, AB =  \sqrt{(1 - 1)^{2}+( - 4 - 5)^{2}}

Or, AB =  \sqrt{0 +81}

Or,  AB = \sqrt{81} = 9

Hence The distance between the givens points is 9 unit  Answer
