To be sure of getting a pair of socks of the same color, you must place yourself in the worst position.
When you take out socks without lookong (radomly), the worst scenary is that the first time you take out a sock of a color and in the second fime you take out a sock of different color. Then, the next time (the third time) you necessarily take a sock that match one of the two taken out previously, and so have a pair.
So, the answer is that you must take out three socks to be sure that you have a pair.
The equation of the line that passes through (4,-1) and (-2,3) is y=-2/3x+5/3. You have to use two points to find the equation. Use the formula y=mx+b to solve.
C(n)=2.00+3.20n
If n = 4 miles:
C(4)=2+3.20(4)
C(4)=2+12.80
C(4)=14.80
The cost of the taxi is $14.80.
Answer:
Step-by-step explanation:
<u>Expand the expression with the help of distributive property.</u>
- 2(q + 3)
- => (2 x q) + (2 x 3)
- => 2q + 6
Hence, the expanded expression is 2q + 6.
