Answer:
3/10 m^2
Step-by-step explanation:
To calculate area of a triangle we multiply height with base and then divide that by 2
2/5 × 3/2 ÷ 2 = 3/10

The number of bottles in a full box is 12.
<u><em>Explanation</em></u>
Suppose, the number of bottles in a full box is ![x](https://tex.z-dn.net/?f=x)
So, the number of bottles in <u>three</u> full boxes ![=3x](https://tex.z-dn.net/?f=%3D3x)
Now, two more boxes are added, both of which have <u>one fewer bottle than the other three</u>. So, the number of bottles in these two boxes ![= 2(x-1)](https://tex.z-dn.net/?f=%3D%202%28x-1%29)
As there were 9 bottles initially and now there are 67 bottles in the fridge, <em><u>so the equation will be</u></em>....
![9+3x+2(x-1)=67\\ \\ 9+3x+2x-2=67\\ \\ 5x+7=67\\ \\ 5x=67-7\\ \\ 5x=60\\ \\ x=\frac{60}{5}=12](https://tex.z-dn.net/?f=9%2B3x%2B2%28x-1%29%3D67%5C%5C%20%5C%5C%209%2B3x%2B2x-2%3D67%5C%5C%20%5C%5C%205x%2B7%3D67%5C%5C%20%5C%5C%205x%3D67-7%5C%5C%20%5C%5C%205x%3D60%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B60%7D%7B5%7D%3D12)
Thus, the number of bottles in a full box is 12.
Answer:
0.98732
Step-by-step explanation:
Given that :
Mean = 10 minutes
Variance = 2 minutes
For less than equal 40 jobs
Mean (m) = 40 * 10 = 400 minutes
Variance = 2 * 40 = 80 minutes
Standard deviation (s) = √variance = √80
Converting hours to minutes
X = 60 * 7 = 420 minutes
P(X≤ 420) :
Z = (x - m) / s
P(X≤ 420) :
Z = (420 - 400) / √80
Z = 20 / √80 = 20 / 8.9442 = 2.236
P(Z ≤ 2.236) = 0.98732
