D $0.66
Because if you do $ 7.55 divide by five you’re gonna get 0.66 so D is the correct answer :D
Price before tip "b" of Kia’s dinner is $ 35
<h3><u>Solution:</u></h3>
Given that kia dinner bill is $ 40.25 which inclused a 15% tip
To find: price before tip "b" of Kia’s dinner
Let us first find the tip amount paid by Kia
Let "b" be the dinner bill before tip
Given that dinner bill is $ 40.25 which inclused a 15% tip
So, 15 % of "b" is the tip amount paid
tip amount paid = 15 % of "b"
Now we can say,
<em>Dinner bill including tip = dinner bill before tip + tip paid</em>
$ 40.25 = b + 0.15b
40.25 = 1.15b
b = 35
Thus price before tip "b" of Kia’s dinner is $ 35

Answer:
This is achieved for the specific case when high quantum number with low resolution is present.
Step-by-step explanation:
In Quantum Mechanics, the probability density defines the region in which the likelihood of finding the particle is most.
Now for the particle in the box, the probability density is also dependent on resolution as well so for large quantum number with small resolution, the oscillations will be densely packed and thus indicating in the formation of a constant probability density throughout similar to that of classical approach.
