Answer:
550 and 803
Step-by-step explanation:
Let the number be N = abc
<u>Then:</u>
- abc/11 = (a² + b² + c²) ⇒ abc = 11(a² + b² + c²)
<u>There are: </u>
- 1000 - 100 = 900 3-digit numbers
<u>Out of 900 numbers:</u>
- 1000/11 - 100/11 = 81 are divisible by 11
The easiest and simplest way is to try them all.
The trial reveals 550 and 803, so this is the answer.
Answer:
The experimental probability P(E) is 0.1818 = 18.18%
Step-by-step explanation:
The experimental probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
11 trials(11 outcomes)
2 kings(2 desired)
So
P(E) = 2/11 = 0.1818
The experimental probability P(E) is 0.1818 = 18.18%
Answer:
Step-by-step explanation:
Let x represent the number of stamps from Europe.
Let y represent the number of stamps from Africa.
Let z represent the number of stamps from Asia.
She has 47 stamps in all. This means that
x + y + z = 47 - - - - - - - - - - - 1
The number of African stamps is 2 times the number of Asian stamps. This means that
y = 2z
She has 20 stamps from Europe. Therefore, substituting x = 20 and y = 2z into equation 1, it becomes
20 + 2z + z = 47
3z = 47 - 20 = 27
z = 27/3 = 9
y = 2z = 2 × 9
y = 18
She has 20 stamps from Europe, 18 stamps from Africa and 9 stamps Asia.
Answer:
0
Step-by-step explanation:
Because 2^3 is 8 and if you multiply it by 0 it will just be 0
6 x 10^8 = 600 x 10^6 compare to 3 x 10^6
Since both now have same exponents
so 600/3 = 200
Conclusion: Answer is 2nd option
6 x 10^8 is 200 times larger than 3 x 10^6
