Sorry i dont know this answer
9. 4- 2(8) = -12
55-40 = 15
so C is true
8. B
3 and 6 i dont know . seems : 4 . C & D are both correct
6 . All correct
Answer:
Step-by-step explanation:
30,100+28,400-230=58,040
58,040
- 6,900
_______
51,140
+ 7,500
________
58940
This is a decay problem,
The equation is written as start value x (1 - rate)^tike
Using the information given in the problem:
a) Total = 120(1-0.12)^Hours
b) Replace hours with 19 and solve:
Total = 120(1-0.12)^19
Total = 120(0.88)^19
Total = 10.57674 mg
Round the answer as needed.
Answer:
It is more reasonable to model the standard class with normal distribution
Step-by-step explanation:
- Standard Class:
The range of grades/marks obtained seems normally distributed with a reasonable average of 65% and covering the entire spectrum. Since most of the students score around average 65% the bump of normal bell curve is well situated about the mean.
- Advanced Class:
The range of grades/marks obtained seems concentrated at around 2 means one for the students with higher ability of mathematics and one for the students with lower ability of mathematics ( Higher for english ). The mathematics abled score in the upper percentile while the English abled score in the mid-lower percentile. The deviation of average scores for is large enough to make this a bimodal distribution rather than a normal distribution. However, there's strong correlation between excelling in one academic subject and excelling in another.
Conclusion:
It is more reasonable to model the standard class with normal distribution
