The answer is 3km as there is 9 secs between it and distance = time/3 and 9/3 =3 so distance =3
Answer:
Step-by-step explanation:
365 x 24 = 8,760
365 x 6 = 2,190
8,760 - 2,190 = 6,570
6,570 / 24 = 273 3/4
Answer:
Converse of the alternate exterior angle theorem
Step-by-step explanation:
just took the test ;)
it would be 160 feet wide
For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.
