Which equation of a line of best-fit reflects a negative correlation?
y = StartFraction 1 Over 70 EndFraction x + 312
y = StartFraction negative 83 Over negative 27 EndFraction x + 15
y = 8 x minus 2
y = negative 6 x + 13

y = negative 6 x + 13

Step-by-step explanation:

A negative correlations implies that the slope is negative, so you just have to solve for y for each to see if slope was negative,

hence the last equation y=-6x+13

y = negative 6 x + 13

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
