<span>In general, the students increased their standardized math scores from 5th grade to 7th grade. The students might be more familiar with the exam and they have learned more in their math classes.</span>

Answer:

Step-by-step explanation:

Given that

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,

This 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.

Step-by-step explanation:

y-y1=m(x-x1)

y-4=-2/3(x-3)

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)

m = \frac{4-6}{8-3} = - \frac{2}{5}, hence

y = - \frac{2}{5} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 4), then

4 = - \frac{16}{5} + c ⇒ c = 4 + \frac{16}{5} = \frac{36}{5}

y = - \frac{2}{5} x + \frac{36}{5} ← equation of line
