Answer:
7/10 or 70%
Step-by-step explanation:
Add the number of each color of balls together to get the total
5 + 2 + 3 = 10
Add the number of all the balls that aren't black
5 + 2 = 7
Then divide how many balls that aren't black by the total. This gives us the probability the ball you choose is not black
7/10 = 0.7 or 70%
If the null hypothesis,

is rejected, then we can conclude that the correlation coefficient is significant. This means that there is enough evidence to conclude that a relationship exists between the two (or more) variables involved in the regression.
Answer:
4(9a^4+4y^2)
Step-by-step explanation:
