Attached solution and work.
Answer:
D
Step-by-step explanation:
The correlation coefficient r=-0.84 denotes that there is inverse relationship between x and y. It means that as the x values increase the y values decrease whereas as the x values decreases the y-values increases. Also, r=-0.84 denotes the strong relationship between x and y because it is close to 1. So, r=-0.84 denotes that there is strong linear relationship between x and y with smaller x values tending to be associated with larger y values.
To find the probability that she develops lung cancer given that she smokes, multiply the two probabilities together:
4/9 x 3/10 = (4 * 3) / (9*10) = 12/90 = 2/15
No solutions exist. Set the function equal to 0. x^2= -25. There are no real solutions to this equation.
Answer:
y = -3x - 5
Step-by-step explanation:
y - 1 = -3 (x + 2)
y - 1 = -3x - 6
y = -3x -5
