The last one is always so. "People will elect Trump by a narrow margin based on a sample of 10000 people with a % error of 2%" is a typical statement.

A probability experiment will always count the number of times an event occurs. That's the whole point of an experimental probability. How many people respond favorably to a new Cancer Treatment is a typical question asked by someone conducting an experiment in probability.

C is kind of iffy. Perhaps it is too expensive, or it takes place over too long a period. Ideally repeat trials  should take place whenever possible. Bone Marrow Transplants are very expensive because of the strict isolation conditions. You're likely only to get one study done this, especially initially. To check to see if Cancer is a generational thing would be an example of a study that takes too long to repeat many times.

B is simply not true. They are not the same. What theoretical model would you use to mimic a survey? You actually have to go do the survey.

A is wrong. It is the other way around. 

Answer C is a maybe but check it. D and E are both true.

Is Social Darwinism a justifiable reason to colonize other areas of the world and exploit the people and resources of that regio
Ksivusya [100]

Answer:

Social Darwinism provided an ideological justification for the social inequalities that capitalism had brought with it: these would result from the hereditary inferiority of the poor and the hereditary excellence of the richer classes, which are best enjoyed under a laissez-faire system. Applied to peoples and races, it became a justification for racism and imperialism.

As can be seen, social Darwinism is a retrograde political and philosophical stance, which considered different ethnic or national groups as different in terms of capacity or development possibilities. Therefore, since this position has been regarded as false, social Darwinism has no justification in our time.

A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 100 feet below the surface aft
den301095 [7]

Answer:

2.3 feet/ second

Step-by-step explanation:

To find the rate of change, we will have to find the difference in his distance travelled and divide it by the time taken to move that distance.

This is given by rate of change = (change in position)/ change in time

From the question, his position changed from 30 ft to 100 ft thus the distance he travelled is = 100ft - 30 ft = 70 ft.

Time taken to travel this distance = 40 seconds - 10 seconds = 30 seconds

Diver's rate of travel = 70 ft / 30 seconds = 2.33333ft/second.

Rounding off the answer to the nearest tenth, we have 2.3 ft/second

Amelia and Barrett sold a total of 137 raffle tickets at the football game. Barrett sold 10 fewer than twice as many as Amelia.
gtnhenbr [62]

Answer:

Barett Sold 88 Tickets

Step-by-step explanation:

To Start off we are told that the Total of tickets sold between Amelia (A) and Barrett (B) was 137.

Total = 137

Since Barett Sold 10 less than twice as many tickets as Amelia, we can make the following equation, where Barett is B and Amelia is A.

A + B = 137

A + (2A-10) =137   (Barett equalls 10 less than twice Amelia)

Now we can solve the equation for A

A + (2A-10) =137

3A - 10 = 137  (Combine Like Terms)

3A = 147 (add 10 on both sides)

A = 49 (divide by 3 on both sides)

Now that we have the amount of tickets that Amelia sold we can plug it in for B to find out how many tickets Barett Sold

(2A-10) = B

(2*49) - 10 = B

(2A-10) = B

98 - 10 = B

88 = B
