Take another photo I can’t see that clearly
So it took an hour an 15 minutes which means the distance traveled is their speed+1/4 of their speed, also any answers that have northbound going faster than 6km/h above south is not right so B and D seems to be out of the picture
There is no solution to this system of linear equations
If n>4, then n+3<2n<3n-2 (n+3<2n is true because this unequality is equivalent to 3<n and 2n<3n-2 is also true because this unequality is equivalent to 2<n). Hence, the side AC is the smallest one and the side AB is the biggest one.
The largest side is opposite the largest angle, the medium side is opposite the medium angle and the smallest side is opposite the smallest angle.
Then, m∠B<m∠A<m∠C.
Answer: m∠B<m∠A<m∠C.
The correlation coefficient r of the data set is <em>-0.28</em>
