Answer:
(-1)/28
Step-by-step explanation:
Simplify the following:
((-19)/2×1/38)/7
(-19)/2×1/38 = (-19)/(2×38):
((-19)/(2×38))/7
(-19)/(2×38)×1/7 = (-19)/(2×38×7):
(-19)/(2×38×7)
The gcd of -19 and 38 is 19, so (-19)/(2×38×7) = (19 (-1))/(2 (19×2) 7) = 19/19×(-1)/(2×2×7) = (-1)/(2×2×7):
(-1)/(2×2×7)
2×2 = 4:
(-1)/(4×7)
4×7 = 28:
Answer: (-1)/28
Answer:
B
Step-by-step explanation:

Answer:
150 7th Graders and 200 8th graders
Step-by-step explanation:
Basically, add the parts of the ratio together and create 7. Then, to find out how much 1 part is equal to, divide the amount of students by the number of parts - so it would be like 350/7 = 50.
So now you know that 1 part is equal to 50 students. From here, you can multiply the two amounts of parts by 50.
3 x 50 = 150 7th Graders
4 x 50 = 200 8th Graders
Hello!
There are only six was to to role a number less than four. 1 and 1. 1 and 2. 2 and 1. 1 and 3. 2 and 2. 3 and 3 and 1.
The first number on the die could be 1, and the second die could have a probability of rolling the second number on it. Giving us a probability of 1/6.
We can subtract the calculated probability from rolling less than four from 1 to find the probability of rolling more than 5:
1 - 1/6 = 5/6
So, your answer should be D 5/6.
