Answer:
70°
Step-by-step explanation:
Minor angle at the centre:
360 - 250 = 110
Two tangents make an angle of 90° each
90 + 90 + 110 + x = 360
x = 360 - 290
x = 70°
The idea is to shift the number enough so that you can cancel the repeating digits by subtraction.
_____
Example
0.181818_18 multiplied by 100 gives
18.181818_18
Subtracting the original number gives
18.000000_00 . . . . . . all the repeating digits have been eliminated
When you multiply by 100 and subtract 1 times the original, you have multiplied by 99. Thus the value of the original number is 18/99 or 2/11.
Using the pythagorean you take the square root of 3^2 and 4^2 to find the shortest distance:
√(3²+4²)=5.
Shortest distance is 5 miles
Based on the given data, the box and whisker plot is constructed and shown below.
Total number of visitors in each month = 100
If you observe the plot of January, you will find that 40 is the 2nd Quartile or the Median value. 50% of the values lie above 40.
So in January, 50% of the visitors were over the age of 40.
50% of 100 is 50.
So,
In January 50 visitors of the beech were over the age of 40.In July, 40 occurs at the 3rd Quartile. Only 25% of the values lie above 3rd Quartile. So In July 25% of the visitors were over the age of 40.
25% of 100 is 25.
So,
In July 25 visitors of the beech were over the age of 40.Thus, in January, there were 25 more visitors over the age of 40 who visited the beech than in July
