Please hurry 50 points. Directions: Write an If… Then… Hypothesis for each of the following research problems.

What effect does high temperature have on the growth of a plant?



What effect does studying with music have on student test scores?



What effect does food color have on the amount of food fish eat?



What effect does light have on plant growth?



What effect does smiling have on teacher giving homework?



What effect does chocolate have on teacher giving homework?



What effect does leaves on a tree have on bird nests?



What effect does acid rain have on the fish population?



What effect does calcium have on bone strength?



What effect does sleep have on student participation in class?

1. If a plant is kept at high temperatures, then it will be stunted in growth.

2. If a student studies with music, then they will have higher test scores.

3. If you add color to a fish's food, then they will eat more of it.

4. If you give a plant constant exposure to light, then it will grow taller

5. If students smile at the teacher, then the teacher will give less homework.

6. If the students bring chocolate to the teacher, then the teacher will give less homework

7. If the tree has a majority of leaves, then the nests will be composed of mostly leaves.

8. If acid rain occurs, then the fish population will decline

9. If a person is lacking calcium, then their bones will break easier

10. If a student gets a full night of sleep, then they will participate more in class

Explanation:

Hypothesis is your guess that you are testing during the experiment. can be pretty much anything as long as it relates to the variables being compared/tested and is in if... then... format

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
