Answer:
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.
18 groups of 12. 18 times 12. That equals 216. 216 can round to 200, 215, or 220.
It looks like 2 and a half and 4/9 both have a common denominator of 18, as 2 goes into 18 9 times, and 9 goes into 18 twice.
Hope this helps!
Answer: A
Step-by-step explanation: While I'm sure there is an equation to solve this which I don't remember I used process of elimination to solve this, there are two right triangle and one of the triangles is sides a, 2, and b. Since B is across from the right angle, it is the hypotenuse, therefore b is greater than a, that means d and b cannot be correct, since a is the same in a and c, we can assume a=8, using Pythagorean Theorem. 8^2 + 2^2= b^2.
b^2 = 68
the square root of 68 can be simplified to 2 * square root of 17
