➷ Calculate the number of hours:
24 x 3 = 72
72/13 = 5.5....
This is 5 whole half lives
You have to half the value 5 times
149/2 = 74.5
74.5/2 = 37.25
37.25/2 = 18.625
18.625/2 = 9.3125
9.3125/2 = 4.65625
The closest value is B. 3.21 so that should be the answer

Do the opposite of the problem
The answer is {1, 2, 10, 50, 75}. It has a median of 10 and a mean larger than 10
Answer:
15
Step-by-step explanation:
If A||B then the sum of given angles must be equal to 180°
2x + 5 + 5x - 80 = 180 add like terms
7x - 75 = 180 subtract 75 from both sides
7x = 105 divide both sides by 7
x = 15
Answer:
Step-by-step explanation:
If two ratios make a proportion then it can be shown as:
Let's verify the answer choices with this method
A. 1/4 and 5/25
- 1*25 = 4*5
- 25 = 20, incorrect, not a proportion
B. 1/4 and 7/24
- 1*24 = 4*7
- 24 = 28, incorrect, not a proportion
C. 1/4 and 10/48
- 1*48 = 4*10
- 48 = 40, incorrect, not a proportion
D. 1/4 and 9/36
- 1*36 = 4*9
- 36 = 36, correct, this is a proportion
