None of them but the last option is the closest. rotating counterclockwise 90° brings it to quadrant 2. then it is directly across from the new one in quadrant 1. all you have to do is reflect it across the y axis
Answer:
95
Step-by-step explanation:
Given data
Number of scores =5
84, 85, 87, and 99
Let the next score be x
Mean =90
So
Total score =84+85+87+99+x
Total score =355+x
Mean=total score /number of score
90=355+x/5
90*5=355+x
450=355+x
450-355=x
x=95
When you walk in a direction and later walk opposite, you can substract both. So
15-3= 12km. Now we use Pythagoras. a2+b2=c2, c being the
hypotenuse. 144+81= 225. Sqrt this and you get 15 km.
