Answer:
The answer to your question is 1.59 km
Step-by-step explanation:
Data
Sign 54 km or 34 mi
1 mi = ? km
Process
1.- Use proportions and cross multiplication to find the answer
54 km ----------------- 34 mi
x km ---------------- 1 mi
x = (1 mi x 54 km) / 34 mi
-Simplification
x = 54 km / 34
-Result
x = 1.59 km
2.- Conclusion
1 mile is equivalent to 1.59 km
We are asked to solve for:
P (sand | positive)
So, we solve this by:
P (sand | positive) = P (sand) x P (positive for sand)
P (sand | positive) = 0.26 (0.75)
P (sand | positive) = 0.195
The probability is 0.195 or 19.5%.
Median = Middle number.
_ _ _ _ _ _
I would put
_ _ 4.5 5.5 _ _
2.5 3.5 4.5 5.5 6.5 7.5
Any numbers work so long as the two center ones have a 'happy median' of 5 (the middle place between the two numbers) and so long as they are in numerical order. There are infinitely many possible solutions to this problem. This is one of many possible answers. Hope this helps :)
Answer:
7/12 or 0.58333333...
Step-by-step explanation:
Basically look for the intersection points of these two functions by setting them equal to each other.
-x^2 + 6x = 21/4 - x/4
-x^2 + (25/4)x - 21/4 = 0
x = 1 and x = 21/4
Plug these points back to any of the two original equations, you will get
(1,5) and (21/4, 63/16)
