10%
This is because the original probability of getting a green marble is 1/3. There are 7 green marbles out of 21 which simplifies to that ratio.
The second probability is 3/10 since there will be 6 green marbles left out of 20 total marbles. This simplifies to that ratio.
Now we multiply the two ratios together.
1/3 * 3/10 = 3/30 or 1/10, which is equal to 10%
Answer:
A
Step-by-step explanation:
Given 2 sides and the included angle use the Cosine rule to solve for x
x² = 1.6² + 1.1² - (2 × 1.6 × 1.1 × cos78° )
= 2.56 + 1.21 - ( 3.52 × cos78° )
= 3.77 - 0.7318
= 3.0382
Take the square root of both sides
x =
= 1.7 → A
The length of the rectangle is 13 meters.
Given that,
- The area of a rectangle is 117 square meters.
- The length is represented by 4+x and the width is represented by x.
We know that
The following formula should be used:

x = 9
So, the length should be
= 4 + 9
= 13
Therefore we can conclude that the length of the rectangle is 13 m.
