P(not 5) =5/6 and P(5) = 1/6
If the first 5 is rolled on the 5th roll then the first four rolls were not 5
P(5 on fifth roll) = 5/6 x 5/6 x 5/6 x 5/6 x 1/6 = 5^4/6^5 = 625/7776 = 0.080375...
X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
They are not the same because one they dont get the same answer and one of the signs are different so it has changed the answer
Answer:
The approximate value of the investment in one year is 4183.
Step-by-step explanation:
The formula for finding the compound interest for one year that compounded quarterly is :

Here,
P - Principal = 4000
r - 4.5%
t - 1
Therefore,



= 4183.08
Hence, the approximate value of the investment in one year is 4183.
1/4x + 5 = =4
subtract 5 to both sides
1/4x = 4 - 5
1/4x = -1
multiply 4 to both sides
x = -1 x 4
x = -4
