I believe the answer is 741,.
Answer:
The solution of the system can be given as (5,-8).
Step-by-step explanation:
Given system of equations:
To solve the given system of equations:
Solution:
We will use substitution to solve the given system.
We will substitute the 
values in terms of 
from the equation into the other equation to solve for
Substituting into .
We have:
<em>Using distribution.</em>
<em>Combining like terms.</em>
Adding 6 both sides.
Dividing both sides by 3.
∴ 
<em>Plugging in into .</em>
We have,
∴ 
The solution of the system can be given as (5,-8).
Answer:
40/3087
Step-by-step explanation:
First, we need to count the number of each type of numbered ball.
Ball Counts: 1 - 5 balls; 2 - 2 balls; 3 - 1 ball; 4 - 2 balls; 5 - 4 balls; 6 - 3 balls; 7 - 1 ball; 8 - 2 balls; 9 - 1 ball, there are then a total of 21 balls
Next, you need to find the probability of each event.
Get less than 4
p(<4) = (5+2+1)/21
p(<4) = 8/21
Get less than 2
p(1) = 5/21
Get exactly 6
p(6) = 3/21
p(6) = 1/7
Next, we need to find the probability of all three events by multiplying the probabilities together.
p(all three) = (8/21)*(5/21)*(1/7)
p(all three) = 40/3087
The probability of all three events occurring is 40/3087.
The multiplier each year is 1.02, so the multiplier for 7 years is 1.02^7.
220,000*1.02^7 ≈ 252,700

4 significant figures is usually good enough for most real-world problems. (Unless you're counting pennies on your billion-dollar investment.)
