Answer:
x = 5/2
Step-by-step explanation:
2^x+4 = 2^3x-1
x + 4 = 3x - 1
3x - x = 4 + 1
2x = 5
x = 5/2
First you do 50 - 32 an that equals 13, so your answer is 13
The value of x based on the information given in the triangle is D. x = 1.
<h3>How to compute the value?</h3>
From the information given, it stated that the triangles are similar.
In this case, both triangles have side 4 and 5. Therefore, we are to find the last side. This will be:
4x - 1 = x + 2
Collect like terms
4x - x = 2 + 1
3x = 3
x = 3/3
x = 1
Therefore, the correct option is D.

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
