Answer:
0.12 = 12%
Step-by-step explanation:
To find this probability, we need to multiply the probability of getting route B, and the probability of getting home by 4 P.M if we choose route B.
If the probability of choosing route A is 60%, we have that the probability of choosing route B is 100% - 60% = 40%
Then, we have that the probability of getting home by 4 P.M. when choosing route B is 30%, so the final probability is:
P = 40% * 30% = 0.4 * 0.3 = 0.12 = 12%
Answer: 226.9 square in.
Step-by-step explanation: Remember that the formula for the area of a circle is (pi)r^2. Since the diameter is 17, you divide that by 2 to get your radius: 8.5. Now, put it into the formula to get your answer. (226.865 is the original, 226.9 is rounded to tenths)
Step-by-step explanation:
3x - 2y = 12
Substituting y = 9, we find:
![3x - 2 \times 9 = 12 \\ \therefore \: 3x - 18 = 12 \\ \therefore \: 3x = 12 + 18 \\ \therefore \: 3x = 30 \\ \therefore \: x = \frac{30}{3} \\ \therefore \: x = 10 \\ \therefore \: A (...., 9) = A (10, \: 9)](https://tex.z-dn.net/?f=3x%20-%202%20%5Ctimes%209%20%3D%2012%20%5C%5C%20%20%5Ctherefore%20%5C%3A%203x%20-%2018%20%3D%2012%20%5C%5C%20%5Ctherefore%20%5C%3A%203x%20%20%3D%2012%20%2B%2018%20%20%5C%5C%20%5Ctherefore%20%5C%3A%203x%20%20%3D%2030%20%5C%5C%20%5Ctherefore%20%5C%3A%20x%20%20%3D%20%20%5Cfrac%7B30%7D%7B3%7D%20%5C%5C%20%5Ctherefore%20%5C%3A%20x%20%20%3D%2010%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20A%20%28....%2C%209%29%20%3D%20A%20%2810%2C%20%5C%3A%209%29%20)
Similarly, solving for point B (4, __) =B (4, 0)
Answer:
99
Step-by-step explanation:
-6-5[-4-(6+12)]+(-5)
Following PEMDAS
We work the parentheses from the inside out
-6-5[-4-(18)]+(-5)
-6-5[-22]+(-5)
Now we multiply
-6+110 -5
Now we add and subtract from left to right
104 -5
99
