Answer:
8.2 million years
Step-by-step explanation:
The time can be found from ...
time = distance/speed
time = (47.0×10^4 m)/(5.7×10^-2 m/yr) = 8.2×10^6 yr
It will take about 8.2 million years for LA to have the same latitude as SF.

Answer:
$4,880.80
Step-by-step explanation:
A = P(1 + r/n)^nt
Where,
A = future value
P = principal = $4,000
r = interest rate = 2% = 0.02
n = number of periods = 2
t = time = 10
A = P(1 + r/n)^nt
= 4000( 1 + 0.02/2)^2*10
= 4000(1 + 0.01)^20
= 4000( 1.01 )^20
= 4000(1.2202)
= 4,880.8
A = $4,880.80 to the nearest cents
Answer: ![P(A) = 0.23](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.23)
Step-by-step explanation:
Given :
![P(A/B) = 0.2](https://tex.z-dn.net/?f=P%28A%2FB%29%20%3D%200.2)
![P(A/B^{1})=0.3](https://tex.z-dn.net/?f=P%28A%2FB%5E%7B1%7D%29%3D0.3)
![P(B)= 0.7](https://tex.z-dn.net/?f=P%28B%29%3D%200.7)
![P(A) = ?](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%3F)
From rules of probability :
........................... equation *
can be written as
x
Also ,
can be written as
x ![P(B^{1})](https://tex.z-dn.net/?f=P%28B%5E%7B1%7D%29)
substituting into equation * , we have
![P(A) = P(A/B)](https://tex.z-dn.net/?f=P%28A%29%20%3D%20P%28A%2FB%29)
![P(B) + P(A/B^{1})P(B^{1})](https://tex.z-dn.net/?f=P%28B%29%20%2B%20P%28A%2FB%5E%7B1%7D%29P%28B%5E%7B1%7D%29)
since P(B) = 0.7, then ![P(B^{1}) = 1 - P(B) = 0.3](https://tex.z-dn.net/?f=P%28B%5E%7B1%7D%29%20%3D%201%20-%20P%28B%29%20%3D%200.3)
so , substituting each values , we have
![P(A) = (0.2)(0.7) + (0.3)(0.3)](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%280.2%29%280.7%29%20%2B%20%280.3%29%280.3%29)
![P(A) = 0.14 + 0.09](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.14%20%2B%200.09)
![P(A) = 0.23](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.23)
Answer:
The distance between points 8 and -5 is 13
Step-by-step explanation:
We need to find distance between points 8 and -5
The formula used to find the distance is: ![Distance=|b-a|](https://tex.z-dn.net/?f=Distance%3D%7Cb-a%7C)
Absolute value is used to get only positive values. i.e |-1|=1 if required.
We are given: b=8 and a=-5
Putting values and finding distance
![Distance=|b-a|\\Distance=|8-(-5)|\\Distance=|8+5|\\Dstance=|13|\\Distance=13](https://tex.z-dn.net/?f=Distance%3D%7Cb-a%7C%5C%5CDistance%3D%7C8-%28-5%29%7C%5C%5CDistance%3D%7C8%2B5%7C%5C%5CDstance%3D%7C13%7C%5C%5CDistance%3D13)
So, the distance between points 8 and -5 is 13
