ANSWER
After 7 years the car will worth, 7,759.5
EXPLANATION
The initial value of the car is 37000.
The rate of depreciation is 20%
In 7 years time, we can calculate the value of the car using the formula,
![A=P(1-r\%)^n](https://tex.z-dn.net/?f=A%3DP%281-r%5C%25%29%5En)
We substitute the values into the formula to obtain,
![A=37000(1-0.2)^7](https://tex.z-dn.net/?f=A%3D37000%281-0.2%29%5E7)
![A=37000(0.88)^7](https://tex.z-dn.net/?f=A%3D37000%280.88%29%5E7)
![A=7759.5](https://tex.z-dn.net/?f=A%3D7759.5)
to the nearest tenth
Answer:
a. 0.349
b. 0.651
c. 0.93
Step-by-step explanation:
According to the Question,
- Given, About 10% of all adults deliberately do a one-time fling and In a group of ten adult friends.
Thus, p=0.10 , n=10 &
Now, Use Binomial distribution = ![\left[\begin{array}{ccc}n\\x\\\end{array}\right]*(p)^{x} *{(1-p)}^{n-x}](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dn%5C%5Cx%5C%5C%5Cend%7Barray%7D%5Cright%5D%2A%28p%29%5E%7Bx%7D%20%2A%7B%281-p%29%7D%5E%7Bn-x%7D)
a. p(x=0) ⇒
= 0.349
Thus, The Probability that No one has done a one-time fling = 0.349
b. p(x≥1) = 1 - p(x=0) ⇒ 1 - 0.349 = 0.651
Thus, The Probability that at least one person has done a one-time fling = 0.651
c. p(x≤2) = p(x=0) + p(x=1) + p(x=2)
p(x≤2) =
+
+ ![\left[\begin{array}{ccc}10\\2\\\end{array}\right]*(0.1)^{2} *{(0.9)}^{8}](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D10%5C%5C2%5C%5C%5Cend%7Barray%7D%5Cright%5D%2A%280.1%29%5E%7B2%7D%20%2A%7B%280.9%29%7D%5E%7B8%7D)
on Solving, we get
p(x≤2) = 0.349 + 0.347 + 0.194
p(x≤2) = 0.93
Thus, The Probability that No More Than two person have done a one-time fling = 0.93
