Answer: 21/100
Step-by-step explanation:
Number of green marbles = 21
Number of blue marbles = 35
Number of red marbles = 18
Number of yellow marbles = 26
Total number of marbles = 100
The probability of choosing a free marble will be:
= Number of green marbles / Tot number of marbles
= 21 / 100
Answer:

Step-by-step explanation:
-Amy walks a distance of 7/8 mile
-Tom walks a distance of 4/8 mile.
#We immediately notice that Amy has walked a longer distance than Tom.
We subtract Tom's distance from Amy's to find how much further Amy walked;

Hence, Amy has walked 3/8 miles further than Tom has.
Answer:
-1
Step-by-step explanation:
Plug in one to the equation to get (1)^3 - 2(1)^2, 1 to the power of anything is 1 so it boils down to 1-2, which is -1

Answer: (4, -3)</h3>
==================================================
Work Shown
We'll be using these vector properties
- Rule 1: (a,b) + (c,d) = (a+c, b+d)
- Rule 2: k*(a,b) = (k*a, k*b)
To get the following
-2u + v = -2*(-1, 5) + (2,7)
-2u + v = (-2*(-1), -2*5) + (2,7) .... apply rule 2
-2u + v = (2, -10) + (2, 7)
-2u + v = (2+2, -10+7) .... use rule 1
-2u + v = (4, -3)
