Answer:
Step-by-step explanation:
The area would be 25 square centimeter
There are eight different possibilities for outcomes of three tosses:
<span>1. Head, Head, Head
2. Head, Head, Tail
3. Head, Tail, Head
4. Head, Tail, Tail
5. Tail, Head, Head
6. Tail, Head, Tail
7. Tail, Tail, Head
8. Tail, Tail, Tail</span>
The 8th possibility will not give us at least 1 head so we will cross that one out. So there is a 1/7 possibility for at least 1 head.
For this case we can make the following rule of three:
1 box -------------> 15 paperweights
x -------------------> 1269 paperweights
We clear the value of x.
We have then:
x = (1269/15) * (1)
x = 84.6
Rounding to the nearest whole:
x = 85
Answer:
There will be needed about:
x = 85 boxes
X= 5.333333333 + .8333333333y
We find the deferential by differentiating the function dy=(3x^2-3)dx
substituting the values for x and dx
dy=(3*2^2-3)(0.05)=0.45
