Answer:
It reduces strength.
Explanation:
It not desirable to produce concrete mixtures of a higher consistency than normal because the strength of the concrete decreases. Consistency plays an important role in the determination of strength of concrete. Less water than normal quantity in concrete increases the consistency but decreases strength due to incomplete chemical reaction while on the other hand, adding more water would increase water-cement ratio and reduces consistency as well as strength of the concrete so that's why necessary amount of water and cement should be added to get higher strength.
Answer:
Facts: Students must take Algebra I before they can take Algebra II. Dara is currently taking Algebra II.
Conclusion: Dara has taken Algebra I in the past.
Explanation:
This fact states that "Students must take Algebra I before they can take Algebra II", meaning there is no possibility that Dora hasn't taken Algebra l. The other conclusions don't have one definitive possibility.
Answer:
Because it is easier to work at a larger scale
Explanation:
Given that a directional hypothesis is a prediction made by a researcher regarding a positive or negative change, relationship, or difference between two variables of a population, a two-tailed test is the perfect tool to validate it because a two-tailed test is designed to examine both sides of a specified data range.
So the final answer to this question is:
True.
