Answer:
D. r=-1 is the correlation coefficient
Answer:
84°
Step-by-step explanation:
I know that the other angle (not x) is 48 because the lengths are the same of 2 sides. Therefore I can use 180-48-48 to get 84, the correct answer.
Answer:
c = 22.8 miles/hr
Step-by-step explanation:
The ship A sails north at the rate of 14 mile per hour , it represent the opposite side of a triangle. Ship B start at the same point and move east at the rate of 18 miles per hour, it represent the adjacent side.
The other rate telling you how fast the distance between them are changing can be computed using the Pythagorean theorem, since the change in time is 1 hour. From 12 noon to 1 pm.
c = ?
a = 14
b = 18
c² = a² + b²
c² = 14² + 18²
c² = 196 + 324
c² = 520
c = √520
c = 22.803508502
c = 22.8 miles/hr
Answer:
30
Step-by-step explanation:
5% of 600 is 30 so that should be ur answer
Ok, I'm only in 8th grade but I believe you do addition first in the problem. Hope this helps! <3
