Answer:3 *3* 3
Step-by-step explanation:
Because your dealing with powers
P=3
We aare given with two inqualities x + y <8 and 3x ≤ y + 6. To solve these inequalities, we replace the less than sign by equal sings. We just transpose y in the second equation to the left side and ad the two equations resulting to x equal to numbers less than 3.5 and y equal to numbers less than 4.5.
<span>To solve this we would need to find the bottom 10% z-score and find c such that Pr(X<c)=0.1. We find that c = -1.2815 using normal distribution. The cutoff salary for teachers in the bottom 10% would be X=26000 + 5000 x (-1.28155) or 19,592.24.</span>
Area = length*width
.. = (1*10^5 mm)*(8*10^4 mm)
.. = (1*8)*10^(5+4) mm^2
.. = 8*10^9 mm^2
Selection A is appropriate.
