Y=mx+b
M equals the slope
B equals the y-intercept So
Y=1x+0
Answer: (a) Independent events , (b) 0.00075
Step-by-step explanation:
Since we have given that
Number of coins = 218
Number of rare Indian pennies = 6
Let Event A: When one of the 218 coins is randomly selected, it is one of the 6 Indian pennies.
Event B : When another one of the 218 coins is randomly selected (with replacement), it is also one of the 6 Indian pennies.
As we know that
![P(A)=\dfrac{6}{218}=0.0275\\\\and\\\\P(B)=\dfrac{6}{218}=0.0275](https://tex.z-dn.net/?f=P%28A%29%3D%5Cdfrac%7B6%7D%7B218%7D%3D0.0275%5C%5C%5C%5Cand%5C%5C%5C%5CP%28B%29%3D%5Cdfrac%7B6%7D%7B218%7D%3D0.0275)
(a) so, they are independent events as there is a condition of 'with replacement'.
(b) P(A and B) is given by
![P(A\cap B)=P(A).P(B)=0.0275\times 0.0275=0.00075](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%3DP%28A%29.P%28B%29%3D0.0275%5Ctimes%200.0275%3D0.00075)
Hence, (a) Independent events , (b) 0.00075
1. 50
2. 5
3. 0.5
4. 0.05
5. 0.005
I hope you see the pattern here . When multiplying the exponent (the small number near the 10) determines the number of zeros to the RIGHT . When dividing the number determines how many zeros to the LEFT usually resulting in a decimal. This is called scientific notation.
Hope this helps!:)
Answer:
2/3
Step-by-step explanation:
Answer: The answer is 65 5/11
Step-by-step explanation: The first portion would be 30km. Second portion not counting coffee stop would be 150km. Since the average speed is distance/Time it would be 180/Time. Time =2 3/4. Answer is 65 5/11. I hope this is correct.
