Answer:
0.6
Step-by-step explanation:
A permutation is an arrangement of outcomes whereas a combination is a grouping of outcomes.
Order matters in case of permutations but does not matter in combinations.
Given:
Number of red marbles = 3
Number of white marbles = 2
Number of green marbles = 1
To find: probability of picking 4 marbles and getting one of each color
Solution:
Total number of outcomes =
= 
Number of favourable outcomes = 2 red, 1 white and 1 green marble + 1 red, 2 white and 1 green marble =
= 
So, probability of picking 4 marbles and getting one of each color = Number of favourable outcomes/Total number of outcomes =
The answer is the option A, which is: A. x-7=x²+2x-4
The explanation is shown below:
To solve this problem you must apply the proccedure shown below:
1. You have the following system equations given in the problem above:
<span>y=x-7
y=x²+2x-4
2. Therefore, when you substitute for y in the bottom equation, you obtain:
</span>x-7=x²+2x-4
Answer:
The two angles mentioned are alternate interior angles, so they are congruent.
303 feet.
Step-by-step explanation:
If you draw off the flag you can see they are alternate interior and are congruent.
Also again, make a diagram it really helps a lot
