Some students are unsuccessful in algebra. The purpose of this quantitative study was to examine the effects of a mathematics intervention class on students' algebraic skills through a pretest-posttest experimental design. This study addressed a missing piece in current literature on previewing, a teaching strategy typically used in language arts. Math intervention was a supplemental math class that previewed algebraic concepts based on the scaffolding theory. Ninety at-risk algebra students were in the study, evenly divided into a control group and an experimental group (i. e., the math intervention). An independent samples t-test was conducted to determine whether the amount of gain was different between these two groups of students. This analysis yielded a statistically significant difference, t(80) = 9.276, p = .0001, indicating the efficacy of the intervention. This study contributes to social change in that the findings demonstrate for school personnel how to proactively prevent at-risk algebra students from getting "left-behind" and help them succeed in algebra. Without math education reform, students may not acquire the math skills required for employment in well-paying jobs in today's economy. What is the sample of this study?

yes

yes yes yes

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
