Answer:
680 students
Step-by-step explanation:
The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.
Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:
number of people that like MATH 123 = 68% of the population
number of people that like MATH 123 = 0.68 * 1000
number of people that like MATH 123 = 680 students

Answer:
compound interest would be,
1495.91
and simple interest would be,
1470
Step-by-step explanation:
compound interest would look like,
1200 x 1.045 x 1.045 x 1.045 x 1.045 x 1.045
and simple interest would look like,
1200 x 0.045 = 54 = 4.5%
54 x 5 = 270
1200 + 270 = 1470
