What kind of association is this, negative or positive?​
erik [133]

Answer:

negative association

Step-by-step explanation:

This diagram is a scatter plot which represents a set of data.  Data on a scatter plot can fit one of three descriptions:  positive (increasing), negative (decreasing) or no association (points do not form any kind of line).  Given this data and the line of best fit, or the line that pass through the majority of the points, it is a decreasing line.  Since the line goes downhill, it is a negative association.

Math help 20 points<br> help
astra-53 [7]

Answer:

1. x =8

2.  x=9

Step-by-step explanation:

Since these figures are parallelograms, the opposite sides are equal.

1.     6 = 2x-10

Add 10 to each side

   6+10 = 2x-10+10

   16 = 2x

Divide  each side by 2

16/2 = 2x/2

 8 =x


2.  x+14 =23

    Subtract 14 from each side

x+14-14 = 23-14

x = 9

So πD ≈ 250 ft

D ≈ \frac{250}{Pi} ≈ 79.57747155

Diameter is approximately 80 ft.
