Answer:
probability is the likelyhood of something occurring. Like, rolling a dice: you have a 1/6 chance of getting a 3. (because it has six sides.)
Answer:
<em>The number is 46</em>
Step-by-step explanation:
<u>Equations</u>
Suppose:
a = One digit of the number
b = Tens digit of the number
The sum of the digits is 10:
a + b = 10
The number expressed as two-digits quantity is ab, and its value is
10a+b
When we add 18 to that number, we have:
10a+b+18
And that is represented as the number reversed:
10a+b+18=10b+a
Simplifying:
9a+18=9b
Dividing by 9:
a + 2 = b
Substituting in the first equation:
a + a + 2 = 10
2a = 8
a = 4
b = a + 2 = 6
Thus the number is 46
E= 140 (1/38) - 4 (37/38)
= -4/19
-0.21
0.21 x 1000 = $210
Answer: -5 and -1
Step-by-step explanation:
-5 * -1 = 5
-5 + -1 = -5 -1 = -6
If x is even, say it's 2. Then what do you need to get to the next even integer (4)? You need to +2. So it would be x + 2, x + 4 and x + 6.
Or, it could be x multiplied. I.e. 2x = 4, 3x = 6, and so on so forth.
