The correct answer is letter "D": technical analysis cannot; fundamental analysis cannot.

Explanation:

In the Efficiency Market Hypothesis (EMH), the semi-strong efficiency exposes that neither technical or fundamental analysis is useful in order to predict price action movements. It establishes that only information that is publicly spread may determine the highs or lows in a stock price.

In that sense, according to the semi-strong efficiency hypothesis, technical and fundamental analysis cannot generate any above-normal return out of a stock price movement.

(a) U

(b) R

(c) R

(d) R

(e) U

(f)  U

Explanation:

According to law of flotation, a floating body will displace the same amount of liquid as the volume of the body itself.

(a) The level of water remains unchanged because the the tackle box weight/volume remains unchanged whether it is on the surface or beneath the water.

(b) The floating balloon must have been holding part of the weight of the son because it is against gravity. Hence, the weight of the son will increase with the loss of the balloon. This will lead to more water volume being displaced and hence, a rise in the level of water in the pond.

(c) The anchor must have been holding some of the weight of the boat including those in the boat. When the anchor is lowered, more weight of the boat is released into the pond and more water volume is displaced. Hence, the water level in the pond rises.

(d) When the balloon is popped, the weight of the son increases because their is no upthrust force opposing his weight. Hence, more water is displaced and the level rises.

(e) When the fisherman lowered himself in water, he will still be displacing his own weight which remains unchanged. Hence the level of water also, remains unchanged.

(f) Since the volume of water is just been transferred from the pond to the man who happens to still be in the pond. The level of water remains unchanged.

Complete Question:

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Types of movies (drama, comedy, adventure, documentary, etc.).

Choose the correct answer below.

A. The nominal level of measurement is most appropriate because data cannot be arranged in an ordering scheme.

B. The ratio level of measurement is most appropriate because ratio are meaningful, and is also a natural zero.

C. The ordinary level of measurement is most appropriate because categories are ordered, but difference cannot be found or are meaningless.

D. The interval level of measurement is most appropriate because differences are meaningful, but there is no natural zero.

A. The nominal level of measurement is most appropriate because data cannot be arranged in an ordering scheme.

Step-by-step explanation:

A level of measurement can be defined as a classification which is used to illustrate the attributes of the values assigned to variables. There are four (4) basic levels of measurement for a variable and these are;

1. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

2. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

3. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

4. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

Hence, the nominal level of measurement is the most appropriate for types of movies (drama, comedy, adventure, documentary, etc.) because data cannot be arranged in an ordering scheme. A nominal level of measurement consists of quantitative variables.

Biology

B) lung volume cannot increase as much and so air pressure cannot decrease

Explanation:

If air will enter the chest cavity then lung will not find proper space to expand. As we all know that pressure and volume both have inverse relation that means an increase in volume leads to decrease in pressure. In short, if volume increases, pressure decreases.

In normal condition, if air enters lungs, the lungs withstand the increased air pressure by expanding themselves. Expansion of lungs volume reduce the pressure which air exerts on them.

But, in pneumothorax condition since the chest cavity where lungs are situated is filled with air so when air will enter the lungs, the lungs will not find required space to expand and air pressure will not decrease leading to short and shallow inspiration.
