Journal Prompt:

You have been asked to conduct an experiment to determine if a new math tutorial program helps improve student grades in class. Your target group is all the students taking Algebra I at your school. There are 300 students and 4 teachers. There are a total of 14 classes throughout the day. Explain how you would conduct your experiment, including a definition of the variables, sampling method, treatments and controls, and possible biases or problems.

i dont know that one is hard

Step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
