Okay so you have 2 equations. so take one and solve for y. ex: y=3+2x
the next equation that involves the y put that in replace of it for ex: 2y=3+3x
2(3+2x)=3+3x
6+4x=3+3x
then solve per usual.
Answer:3
Step-by-step explanation:
By the empirical rule, 95% of the distribution is within 2 standard deviations. Since the other 5% is split equally between the two tails of the distribution, the empirical rule says 2.5% will be below -2 standard deviations from the mean.
... 266 days - 2×(16 days) = 234 days
The shortest 2.5% of pregnancies last less than 234 days.
