We determine the minimum and maximum scores that Juan needs to get in order to be within the strict average range. We let x be his score.
minimum:
74 = (82 + x) / 2
The value of x from the equation is equal to 66.
maximum:
80 = (82 + x )/2
The value of x from the equation is equal to 78.
Hence, Juan's score should fall between 66 and 78, inclusive.
Answer: <em> 66 ≤ x ≤ 78</em>
In this question, it is given that
Curium-243 has a half-life of 28.5 days. In a sample of 5.6 grams of curium-243.
And we have to use the following formula, which is
Here t=12 days, half life, h =28.5 days . And the initial value ,A(0)=5.6 gms
So we will get
Therefore after 12 days, 4.2 gmsof curium-243 remains .
