Answer:
Step-by-step explanation:
Let X be the length of pregnancy.
X is N(268, 15)
a) Prob of pregnancy lasting 307 days or longer
= P(X>307) = 
=0.5-0.4953
=0.0047
b) Lowest 2% is 2nd percentile
Z=-2.55
X score = 268-2.55(15)
= 229.75 days
If length of days >230 days then it is not premature.
Sine 35 degrees = x / 20
x = sine 35 degrees * 20
x = .57358 * 20
x = 11.4716
Answer:
y is 15 x is 3
Step-by-step explanation:
87 / 114 = x / 9918....87 people to 114 = x people to 9918
cross multiply
(114)9x) = (87)(9918)
114x = 862866
x = 862866/114
x = 7569 <===
