Answer:
the probability of picking an odd number is 7/10
The probability of getting an odd number is 7/10.
Step-by-step explanation:
There are 7 odd numbers: {1, 3, 7, 9, 15, 19, 21}
There are 3 even numbers: {2, 10, 20}
There are 10 numbers overall: {1, 2, 3, 7, 9, 10, 15, 19, 20, 21}
7 odd numbers out of 10 numbers is equal to 7/10
The number is 7
let the said number be x
Nineteeen less than 6 times a number;
6x - 19
equals; 16 more than the number; this is 16 + x
Thus;
6x - 19 = 16 + x
6x-x = 16 + 19
5x = 35
x = 35/5
x = 7
83
Add the numbers together
a repeating decimal is placed over 9's instead of 0's. for example: 0.23 = , but 0.232323... =
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x =
d) -2 <em>= -2 when simplified</em>
The number is rational becase it has a repeating decimal
