Answer:
21
Step-by-step explanation:
- AC = 64
- AB = 7x + 8
- BC = 3x + 6
<u>Since AC = AB + BC</u>
- 7x + 8 + 3x + 6 = 64
- 10x + 14 = 64
- 10x = 50
- x = 50/10
- x = 5
------------------
BC = 3x + 6 = 3*5 + 6 = 21
Starting point: (0, 2) and can go to (1, 6).
This shows the slope and y-intercept. Hope this helps.
The correct answer is 2x-1
Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.
Prime numbers 2,3,5,7,11,13,17,19,23
so 2+3+5=10 no
3+5+7=15 no
3+5+11=19 Yes this is your answer
