Answer:
For a green and a blue P1 = 8/11 * 3/10 = (80 * 33) / 110^2 = .218
For a blue and a green P2 = 3/11 * 8/10 = (30 * 88) / 110^2 = .218
The probabilities are the same
Answer:
This condition is true.
Step-by-step explanation:
A sample of 2,845 auto workers was selected to learn if they would go on strike.
Over 50% of those in the sample declared they would strike.
We can assume that the majority of all auto workers favor a strike. This is true because, in the sample, it is declared that 50% of workers would strike.
And this sample represents the whole majority or population. Hence we can say that a majority of all auto workers favor a strike.
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?
