These 'l l' lines mean absolute value. essentially it's asking how many units away from 0 a number is. Because of this all absolute values are positive numbers
l-18l=18
Answer: B. 95.0
Step-by-step explanation:
In statistics , the famous empirical rule says that " if the data is normally distributed then 68% of the observations will be contained within 
standard deviations from the arithmetic mean, 95% of the observations will be contained within 
standard deviations from the arithmetic mean and 99.7% of the observations will be contained within 
standard deviations from the arithmetic mean".
Hence, B is the correct answer.
Subtract y
3x - y + 5 = 0
Answer:
D
Step-by-step explanation:
This is exponential growth, and to my understanding, the format goes:
<em>initial amount (percent growth/ decay)^time</em>
percent growth = (<em>decimal percent + 1)</em>
<em>percent decay = (1 - decimal percent) </em>
Your equation:
1500(1.02)^t
Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.
i think
I believe is 70 multiply 1400 times 5% and it will give you 70
