Answer:
18%
Step-by-step explanation:
Iliana's math grade increased from 65 to 86.
So, the percentage increase in the her math grade will be
% (Approximate)
Now, Fiona's math grade increased from 70 to 80.
Hence, the percentage increase in her math grade will be
% (Approximate)
So, the difference rounded to the nearest whole number between the approximate percent increases in math grades will be
(32.31 - 14.28) ≈ 18%
So, it is eighteen percent. (Answer)
Logan's monthly bank statement showed the following deposits
and withdrawals:
$31.34, $117.42, -$52.48, -$102.33, $64.90
If Logan's balance in the account was $82.63 at the
beginning of the month, what was the account balance at
the end of the month
Answer:
Step-by-step explanation:
Given that Bill, George, and Ross, in order, roll a die.
The first one to roll an even number wins and the game is ended.
Since Bill starts the game he can win by throwing even number or lose by throwing odd number
P(win) = 0.5, otherwise, the die will go to George. For Bill to win, both George and Ross should throw an odd number so that Bill again gets the chance with game non ending.
Thus we have Prob of Bill winning =P of Bill winning in I throw +P of Bill winning in his II chance of throw +....infinitely
To get back the dice once he loses probability
= p both throws odd = 
Thus Prob for Bill winning
=

We have two equations that were solved by Nikki and Jonathon:
Equating the above two:
⇒ 1.3x + 1.6 = -2.7x + 3.2
⇒ 4x = 1.6
⇒ x = 0.4
Hence, substituting the value of x in one of the equations we get:
y = 1.3×0.4 + 1.6 = 2.12
So the solution is (0.4, 2.12)
Jonathon's solution was (0.4, 2.12) and Nikki's was (2.25, 0.5). Hence Jonathon gave the correct solution.
