2 answers:
Answer:262 days
Step-by-step explanation:
Pregnancy 1=270 days
Pregnancy 2= 260days
Pregnancy 3=272 days
To find cumulative days for all four pregnancies to equal an average of 266days
For the average to be 266 days
266×4=1064
Sum of all 3 pregnancies = 270+260+272=802
Sum of all cumulative days for all four pregnancies-sum of the three pregnancies
1064-802=262
So for the average to be 266days
The forth pregnancy has to
262 days
266 * 4 = 1064 days. The total days she’s been pregnant is the sum of those 3 pregnancies which is 802 days. Therefore, she needs her pregnancy to be 262 days to equal the average.
