Answer:
68 %
Step-by-step explanation:
(a) Using the 68-95-99.7% rule, between what two lengths do the most typical 68% of all pregnancies fall?
95%? 99.7%?
The middle 68% of all pregnancies last between 266-16 and 266+16 days, 250 to 282. The middle 95% of all
pregnancies last between 266-2*16 and 266+2*16 days, 234 to 298 (for future reference, note that this “rule” is
rounded somewhat compared to the charts). The middle 99.7% of all pregnancies last between 266-3*16 and
266+3*16 days, 218 to 314.

Answer:
(2, 0)
Step-by-step explanation:
First, find how the other point was transformed:
The x coordinate increased by 1, and the y coordinate increased by 4.
Now, do these same transformations to the other point, (1, -4)
x coordinate: 1 + 1 = 2
y coordinate: -4 + 4 = 0
So, the new point is (2, 0)
