If ABCD is a parallelogram, we have to prove that slope of AB = CD and slope of BC = DA. Using the formula m = (y1-y2) / (x1-x2), the slope of line segment AB = 0/-4,  CD = 0/-4, BC = 1, DA  = 1. Going back to the condition, the slope we get for each line segment proves that ABCD is a parallelogram.

The length of a rectangle is 4 more than twice the width. If the perimeter of the rectangle is 104 centimeters, what are the len
qaws [65]

Answer:

Make Width = 'x'

Length = 4 + 2x

Perimeter = 2 x Width + 2 x Length

86 = 2(x) + 2(4 + 2x)

86 = 2x + 8 + 4x

Collect like terms:

2x + 4x = 86 - 8

6x = 78

x = 13

Width = 13 cm

Length = 30 cm

ddd [48]

Answer:

Absenteeism significantly increases cost.      

Step-by-step explanation:

We are given the following in the question:

The Sensor Dynamics Corporation did a scientific study on the impact of absenteeism on increased costs.

The correlation between the two was found to be 0.7

Correlation:

  • It is a measure of linear relationship between two quantities.
  • A positive correlation means that an increase in one quantity leads to an increase in another quantity
  • A negative correlation means with increase in one quantity the other quantity decreases.
  • Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.

Thus, we can say that there is a high positive correlation between absenteeism and cost.

Thus, absenteeism significantly increases cost.
