Answer:
0.368
Step-by-step explanation:
Number of red marbles= 3
Number of blue marbles= 4
Number of green marbles= 7
Total number of marbles= 3+4+7= 14
Let the first ball is taken out to be red
P(R)=
than again a second ball is drawn, number of balls left= 14-1=13
Number of red= 2
P(R)=
Total probability=+
Total probability= 0.368
Hence, the correct answer is 0.368
Answer:
1) (2, 3)
2) (2, -5).
Step-by-step explanation:
2x – y = 1
2x +2y = 10 Subtract to eliminate the 2x:
2x - 2x - y - 2y = 1 - 10
-3y = -9
y = 3.
Plug this into the first equation:
2x - 3 = 1
2x = 4
x = 2.
2)
5x – y =15
x + y = -3 Adding to eliminate y:
5x + x - y + y = 15 + -3
6x = 12
x = 2
Plug this into the first equation:
5(2) - y = 15
-y = 15 - 10 = 5
y = -5.
To find missing lengths of sides

<em><u>Answer:</u></em>
s = $39,340
<em><u>Explanation:</u></em>
Note: I will use the symbol "n" instead of "t" in the solution.
<u>The given formula is:</u>
s = 32,512 * (1.1)ⁿ where "n" is the number of years.
We want to get the salary after 2 years. This means that we will substitute with n = 2 in the above equation and get the value of s.
<u>This is shown as follows:</u>
s = 32,512 * (1.1)²
s = $39,339.52 which is approximately $39,340
Hope this helps :)
