Answer:
70.2%
Step-by-step explanation:
Given data
Initial weight =172 pounds
Final weight = 185 pounds
% increase= Final - Initial / final *100
% increase=185 - 172 / 185 *100
% increase= 13 / 185 *100
% increase=0.0702*100
% increase=70.2%
Hence the increase is 70.2%
You could simulate this by allowing the numbers 1-4 to represent a correct answer and the numbers 5-6 to represent an incorrect answer. This would have a 2/3 probability of the question in the simulation being correct.
In this problem we know that total minutes are 80 and
80 - M = 15
let's solve by steps
Step 1 - adding M on both sides
80 - M + M = 15 + M
80 = 15 + M
Step 2 - subtract 15 from both sides
80 - 15 = 15 - 15 + M
65 = M
So, 80 - 65 = 15
Hence verified.
Hope this helps you :)
I think the points given here are plotted linearly:
FGHI. in this case, we can tell that FG + GH + HI = FI. substituting to the expression devised, 2 units + GH + 1 unit = 7 units. This is equal to 3 units + GH = 7 units. GH is then equal to 4 units.
