Part A:
Finding the probability of P(Z < -1.27), we refer to the z-table to the left of the distribution and we have
Therefore
Part B:
Doing the same process as above, however we also need to find the P(Z < 1.68)
Solving for P(-1.27 < Z < 1.68) we have
9.8 is the furthest from everything else, making it the outlier.
14-2 is 12÷1.5 is 8. It will take 8 years for the tree to be 14 foot tall
Answer:
y=x^2-13x+42
Step-by-step explanation:
y=(x-6) times (x-7)
y=x^2-7x-6x+42
collect like terms
y=x^2-13x+42
There you go
