Answer:
i = 45% and ii = 47% (Rounded)
Step-by-step explanation:
Simply divide 27 by 60 to get i:
27/60=.45
Convert to a percent chance.
.45=45%
Then divide 395 by 840 to get ii:
395/840=.47
.47=47%
821
(-3,5)
When you reflect over the x axis, the y value's sign changes.
So we have:
-3,5
40.3
Use pythagoras theorem, a^2 + b^2 = c^2
400 + 1225 = 1625
sqrt of 1625 = approx 40.3
12-3x ..... 12=3x .... x=4
