Answer: India's rice production would increase by 12.8%
Explanation:
Note that India's production in 2004 is approximately 88,000,000 tons and this is the starting value.
China's production is approximately 112,000,000.
If y is the annual percentage increase, written as a decimal, then the multiplier for a y percent increase is
(1 + y).
India's value of 88 million tonnes must be multiplied by this multiplier twice in order to equal China's output.
Therefore:
y = 0.128 = 12.8%.
Answer:
Accept H0
Explanation:
A group of psychologists was interested in knowing whether living environment had any effect on a student's grade point average (GPA). They took a set of twins and randomly assigned one sibling of the twins to live in an urban area and the other to live in a rural area After one year, they computed the GPAs for the twins and looked at the differences. Then they calculated the test statistic, and the P-value was found to be between 0.20 and 0.25. With a 0.05 level of significance, we should <u>accept</u> H0, and conclude that there is insufficient evidence to suggest that a difference exists between the mean GPAs of the two living environments.
A p value that is less than or equal to 0.05 suggest strong evidence against the null hypothesis, so you reject the null hypothesis. A p-value greater than 0.05 indicates weak evidence against the null hypothesis, so you accept the null hypothesis. In this study, the null hypothesis will be "living environment has no effect on a student's grade point average (GPA)", and since the p value obtained from the study is greater than 0.05, we accept the null hypothesis.
Answer:
C. The symbolic thinking of children in this stage is limited.
Explanation:
Jean Piaget was a Swiss physiologist who is well known for his theory of cognitive development which is divided into four developmental stages and the second stage among them is the Pre-operational stage. It is the second stage in which children between the age of approx two and seven years make understanding of the world around them.
At this stage, children start to think in images and symbols but they cannot understand the concrete logic behind it. At this stage, they start to indulge in role-playing and pretending. However, ego-centrism resists them to accept the viewpoint of others.
Answer:
The correct answer is letter C. Whether a clue about a word’s sound is more helpful for recall than a clue about its meaning depends on how the word was thought of when it was learned.
Explanation:
The affirmations of letter A, B or D, are not true because:
- Recall performance is usually <u><em>not as good</em></u> as recognition performance (recognitions is the fraction of relevant instances while recall is the <em>fraction of the total amount</em> of relevant instances)
- Recall performance <u><em>benefits</em></u> from context reinstatement;
- Physical context<u> </u><u><em>isn’t</em></u><em> more important </em>to recall than psychological context (emotional state can play an important role in recall performance).
Answer:
mechanical energy
Explanation:
The spinning blades turn a coil of wire inside a generator that is directly behind the blades. The generator changes the mechanical energy of the moving blades into electrical energy.
