Answer:
1/2
Step-by-step explanation:
since there are an equal number of boys and girls in the class, there is a 50% chance there will be all girls or all boys
So after every 2 hours the bacteria's numbers double (or 100% is "added") so we can simplify 12 down to 6 because we only want the number after every two hours, 400+800+1600+3200+ 6400+ 12800 = 25200 total after 12 hours
Answer:
RS = 2
Step-by-step explanation:
Points R, S, and T are collinear, and S is between R and T, in addition, RS = 2x-4, ST = 3x+2, and RT = 13. Find the value of RS
Hence:
RS + ST = RT
2x - 4 + 3x + 2 = 13
2x + 3x - 4 + 2 = 13
5x - 2 = 13
5x = 13 + 2
5x = 15
x = 15/5
x = 3
To find the value of RS
RS = 2x-4
RS = 2 × 3 - 4
RS = 6 - 4
RS = 2
