All tests for the first six chapters of a textbook had 20–30 questions. the chapter 7 test will be given tomorrow. what reasonable conclusion can you make?

We can conclude that the chapter 7 test will also have 20-30 questions on it.

Step-by-step explanation:

All tests for the first six chapters of a textbook had 20–30 questions.

The chapter 7 test will be given tomorrow.

Hence, based on reasoning, we can say that the chapter 7 test can also have 20-30 questions in it.

The probability is also high as all the 6 previous tests had 20 to 30 questions. Hence, it is very likely that the 7th test will also have same number of questions.

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.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
