Answer:
Bigger number = 42
Smaller number = 10
Step-by-step explanation:
Step 1: Define variables
<em>x</em> = larger number
<em>y</em> = smaller number
Step 2: Write systems of equations
x + 2y = 62
3x = y + 116
Step 3: Rewrite 1st equation
x = 62 - 2y
Step 4: Substitution
3(62 - 2y) = y + 116
186 - 6y = y + 116
186 = 7y + 116
70 = 7y
y = 10
Step 5: Plug in <em>y</em> to find <em>x</em>
x + 2(10) = 62
x + 20 = 62
x = 42
Answer: 16/9 or 1 7/9
Step-by-step explanation:
plug in the values
4 2/3 + 2/3 * 1/2
add the first two values
4 2/3 + 2/3 = 4 4/3 or 5 1/3
multiply 5 1/3 by 1/2
5 1/3 * 1/3 = 16/9 or 1 7/9
Check if this is correct.
If a person after 10 steps is at his starting position, then this person takes 5 steps forward and 5 steps backward.
This is a binomial distribution with
- probability to take step forward
- probability to take step backward
Then
