I'm not for sure but I think it's ten
Variable B : 8, 3, 2, 6, 2, 1, 3, 5
To get the range of a set, we need to arrange the numbers from least to greatest
1, 2, 2, 3, 3, 5, 6, 8
We get the difference of the greatest number and the lowest number.
8 - 1 = 7
The range of the set is 7.
In 3 hours half of 700 would be 700/2=350
in 3 more hours, so 6 total, the half life would be 350/2 = 175
in 3 more hours, 9 total, the half life would be 175/2 = 87.5
in 3 more hours, 12 total, the live life would be 87.5 / 2 = 43.75
so it would be 12 hours to have less than 50 mg
Answer:
x = -1.5 y = 4
Step-by-step explanation:
4x + 3y = 6
-4x + 2y = 14 Add both equations together
5y = 20 Divide both sides by 5
y = 4
Plug this into one of the original equations
4x + 3(4) = 6 Multiply
4x + 12 = 6
-12 - 12 Subtract 12 from both sides
4x = -6 Divide both sides by 4
x = -1.5
