Answer:
5/12
7/12
125/36 = 3,47%
50/11 = 4,54%
Step-by-step explanation:
Probability a black sock is selected when a person chooses 1 sock = 5/12
Probability a white or brown sock is selected when a person chooses 1 sock =
7/12
Probability a person chooses 3 socks and selects a white first, a black second, and a brown last if the socks are replace = (4/12 * 5/12 * 3/12)*100 =125/36 = 3,47%
Pobability a person chooses 3 socks and selects a white first, a black second, and a brown last if the socks are NOT replace = (4/12 * 5/11 * 3/ 10)*100 = 50/11 = 4,54%

Have a good day :)
Answer:
Step-by-step explanation:
chickens + goats = 13
so...
c + g = 13, so...
g = (13 - c)
2 legs times the number of chickens (2c) + 4 legs times the number of goats (4g) = 48 total legs. So...
2c + 4(13-c) = 48, so
2c + 52 - 4c = 48, so
-2c = -4, so
2c = 4, so
c = 2.
There are 2 chickens, and therefore 11 goats.
Scalene = yes it is possible (example: 105 degrees, 5 degrees, 70 degrees)
Right = No, the reason why is because the remaining angles must add to 90 which is less than a right angle. So it's impossible to have one angle over 90 degrees.
Acute = Also no. All three angles are less than 90 degrees
Isosceles = Yes. It is possible. One example would be 120 degrees, 30 degrees, 30 degrees.
Slope of 1 is -2/5. intercept is 3
slope of 2 is 1/4. intercept is 3
