Answer:
0.79
Step-by-step explanation:
add up the probability that is less than or equal to 0, which is 0.17+0.13+0.33+0.16 = 0.79
You simply switch the odds, the answer would be b:a
Roosters to chickens is 2 to 8
That means where there are 2 roosters, there are 8 chickens.
Simplify the ratio 2:8
The ratio can be simplified to 1:4
So, for 1 rooster, there are 4 chickens.
Now, the question says that if there are 5 roosters, how many chickens will there be?
1 rooster to 4 chickens
5 roosters to ? chickens
We went from 1 rooster to 5 rooster. We multiplied by 5.
To find out how many chickens there are for 5 roosters, multiply 4 chickens by 5.
4 * 5 = 20
Where there are 5 roosters, there will be
20 chickens.
Another way to solve is as follows:

Your final answer is
20 chickens.<span />
Step-by-step explanation:
2x + 7x - 10 = 180° because these rwo angles are supplementary
10x - 10 = 180°
10x = 190° divide both sides by 10
x = 19
measure of angle on the right:
8x - 10 ➡ 8 × 19 - 10 = 142°
measure of angle on the left:
2x ➡ 2 × 19 = 38°
Given:
Consider the below figure attached with this question.
To find:
The value of x.
Solution:
According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.
In triangle ABC, using exterior angle theorem, we get



The value of x is 105 degrees.
Therefore, the correct option is C.
