(1) FOUR LESS THAN THE PRODUCT OF 4 AND A NUMBER is 4x - 5 = 5
(2) THE PRODUCT OF FOUR AND THE DIFFERENCE OF A NUMBER AND FIVE is 4 (x-5)
(3) THE PRODUCT OF FOUR AND THE SUM OF A NUMBER AND FIVE is
4 (x+5)
The answer is 0.01703577512
Answer:
no y does not
Step-by-step explanation:
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
