Answer:
a. The expected number of adults who smoke is 70
b. The probability that fewer than 20 smoke is 5.7%
c. The probability that from 45 to 80 smoke is the 12,8% to 22,8%
d. The probability that 70 or more smoke is the 20%
Explanation:
a. 350 is the 100% so you have to do a equation
350 -100%
X - 20% = 20% x 350/100 = 70 adults
b. 350 -100%
20 - X = 20% x 100%/350= 5.7% probability
c. 350 - 100%
45 - X = 45 x 100%/350= 12.8% probability
350 - 100%
80 - X = 80 x 100%/350= 22.8% probability
d. 350 - 100%
70 - X = 70 x 100%/350= 20% probability
Answer:
A. Setting up an environment that’s familiar yet appropriately challenging
Explanation:
J. McVicker Hunt proposed a concept known as "<em>problem of the match</em>" that illustrates the importance of the development of the mental functions in children. In this concept, a child forms higher abilities through learning activities that are not too simple but not too challenging. Therefore, the child is able to perform a task with only a little help.
In the <em>problem of the match</em>, the adult analyses and is able to adjust the level of challenge of the previously-mentioned task in order<u> to ensure that the child is learning and, at the same time, avoiding frustration by being too challening or overwhelming.</u>
<u />
Therefore, this concept refers to <u>setting up an environment that's familiar yet appropriately challening.</u>
