slavikrds [6]

Answer:

social facilitation

Explanation:

The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.

This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of

julsineya [31]

Answer:

- 100 grams of food A (x)

- 60 grams of food B (y)

Explanation:

According to this question, the group of laboratory rats are being fed a daily diet of:

- 125.6 units of niacin and 5,400 units of retinol

Let x represent the number of grams needed for food A.

Let y represent the number of grams needed for food B.

This means that:

Food A: Niacin = 0.86x, Retinol = 30x

Food B: Niacin = 0.66y, Retinol = 40y

Since there are 125.6 units of niacin fed to the rats in total, then;

0.86x (A) + 0.66y (B) = 125.6

Since there are 5400 units of retinol fed to the rats in total, then;

30x (A) + 40y (B) = 5400

Solving these two equations simultaneously using elimination method:

0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)

30x (A) + 40y (B) = 5400 ............ (eqn 2)

Multiply eqn 1 by 30 and eqn 2 by 0.86

30 × 0.86x + 0.66y = 125.6

0.86 × 30x + 40y = 5400

25.8x + 19.8y = 3768 ............ (eqn 3)

25.8x + 34.4y = 4644 ........... (eqn 4)

Subtract eqn 3 from eqn 4

14.6y = 876

Divide both sides by 14.6

y = 876/14.6

y = 60

Substitute value for y (60) into eqn 2

30x + 40y = 5400

30x + 40(60) = 5400

30x + 2400 = 5400

30x = 5400 - 2400

30x = 3000

x = 3000/30

x = 100

Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).
