Step-by-step explanation:
students in 7th grade took a standardized math test that they also had taken in 5th grade. the collected data showed that in two years the median increased by three points, and the mean increased by around two and a half points. In terms of the context,
that proves that there is overall improvement in the grades of students.but there is a small difference between mean increase and median increase.
While median increased 3 points, mean increased only by 2.5 points. This implies there exists unusually low level iq students who had unusually low score thus affecting mean to be low.special training should be given to those students.
The answer is A because if you graph 2x from the origin you will get the blue line perfectly whereas y=-4x plotted will come up with your red line and walla. :)
Answer:
-2
Step-by-step explanation:
4x=4-12
4x=-8
X=-2
And answer is - 2
A³ b² 4ab³
Rearrange order:
4 a³ a b² b³
Now add up the exponents from same base:
4 a³⁺¹ b²⁺³
4 a⁴ b⁵
Final answer: 4 a⁴ b⁵
