My "technology" tells me the correlation coefficient is about -0.1293.

It means there is very little correlation between average mile time and weekly mileage. What correlation there is suggests that in some cases, more weekly mileage may correspond to (very slightly) faster speeds (reduced average mile time).

What is the value of X plz help

Tema [17]

Answer:

x = 16

Step-by-step explanation:

(5x + 12)° + (6x - 8)° = 180°

(5x + 12 + 6x - 8)° = 180°

(11x + 4)° = 180°

11x + 4 = 180

11x = 180- 4

11x = 176

x = 176/11

x = 16
