Answer:
1
Step-by-step explanation:
A coin only has two outcomes. Meaning that she has a 50/50 chance of landing on each side. So, 50% of 20 is 10. According to the theoretical probabilty, the coin would have landed on heads 10 times and tails 10 times. So, for that to be true Maria would have had to land on tails one more time.

Answer:
<em>The actual distance between Rose Lake and the hiking trail is 7 miles.</em>
Step-by-step explanation:
The actual distance between Rose Lake and the main road is 3.5 miles and the scaled distance on the map is 2 inch.
Suppose, the actual distance between Rose Lake and the hiking trail is 
miles.
Given that, the scaled distance from Rose Lake to the hiking trail on the map is 4 inch.
So, <u>according to the ratio of "scaled distance" to the "actual distance"</u>, the equation will be......
Thus, the actual distance between Rose Lake and the hiking trail is 7 miles.
Answer:
Step-by-step explanation:
The interior is a parallelogram when adjacent angles are supplementary. This requires ...
(x -30)° + (x +50)° = 180°
2x + 20 = 180 . . . . . . . . . . . collect terms, divide by °
2x = 160 . . . . . . . . . . . . . . . subtract 20
x = 80 . . . . . . . . . . . . . . . . . divide by 2
Then the angle x+50 is ...
(x +50)° = (80 +50)° = 130°
This is also the measure of the angle marked y.
For the lines to be parallel, x = 80, y = 130°.
