Since there are 5 choices and there are 10 possible digits for each digit of the PIN( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
The total value possible 5 pins are 10⁵ = 100000
Using permutation, since 5 numbers are selected without repetition:
The probability that no numbers are repeated is= 30240/ 100000
≈ 0.302
Answer:
Step-by-step explanation:
60942.44577
anwser is ii
487 is almost 500, so we will approximate 487 as 500.
310 is just over 300, so we will approximate 310 as 300.
300+500=800 (estimation)
310+487=797 (actual)
Answer:
area = 2 π r 2 + 2 π r h
Step-by-step explanation:
First of all, we need to deduce the price of a single camera:
Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have
This equation literally says: 36 is x-percent of 150. And we need to solve for x:
