Three tenths is the same as 3/10

the sum of -2 and -28 is -30

3/10 of -30 is the same as the products of the two

3 x -30 / 10 = -90/10 = -9

Your answer is


3(-2 + -28)/10 = -9

14. For a prism, the volume is given by
.. V = Bh . . . . . . . . where B is the area of the base, and h is the height of the prism

For a pyramid, the volume is given by
.. V = (1/3)*Bh . . . . where B is the area of the base, and h is the height of the pyramid

The volume is proportional to the area of the base. If the dimensions of the base decrease linearly to zero at the height of the geometry as they do for pyramids and cones, then the volume formula includes a factor of 1/3.


15b. The volume of a pyramid is 1/3 that of a prism with the same base area and height.

Mila [183]

Answer:

Step-by-step explanation:

1. The independent variable in this experiment would be the separation of students into distinct groups based on standardized tests of ability and achievement.

2. To implement the independent variable, the experimenter needs to divide the 100 volunteers into separate groups based on standardized tests of ability and achievements. He must also make sure that each groups’ students’ ability levels are the same. Then they would be given tasks as per their ability level.

3.The dependent variable here would be the academic achievements of the groups formed based on ability.

4. First, the volunteers’ achievement would be tested. Then based on their abilities as per standardized tests, they would be divided into groups of students with similar abilities. Then they would be given tasks as pr their abilities. Finally, their achievements would be measured to see if there is any significant difference in achievement between them before and after the grouping as per ability.

5.

6. Null Hypothesis: There would be no significant difference between the academic achievements in high school students of varying abilities due to separation into distinct groups based on standardized tests of ability and achievement.

Alternative Hypothesis: There would be a significant difference between the academic achievements in high school students of varying abilities due to tracking.
