Step-by-step explanation:
the arrows from the picture tells us that TV is parallel to RS
since TS is a transversal that cuts the 2 parallel lines TV and RS than ∠S =x
(alternate interior angles)
sum of angles in a Δ is 180° so x+x+2x = 180°, 4x =180°, x= 45°
2x = 45*2 = 90°
Answer:
The standardized score (z-score), relative to all U.S. births, for a baby with a birth length of 45 centimeters is<u> 2.88cm . </u><u> </u>
Step-by-step explanation:
It is given that the mean length of the babies born after the 40 weeks gestation period is 52.2cm
Standard deviation = 2.5
Baby born on one month earlier having mean length = 47.4cm
