The center of the clock is taken as the origin.The clock is a circle with a diameter 10 units.Radius is half the diameter .Radius = 10 ÷2= 5 units.
The clock is divided in four quadrants .On x axis y=0 and on y axis x=0.
When it is 12 o'clock the hour hand is on positive of y axis.Coordinates of the point at 12 o'clock=(0,5)
When it is 3 o 'clock the hour hand is on positive of x axis .Coordinate of the point at 3o'clock is (5,0)
When it is 6 o'clock the hour hand is on negative of y axis .The coordinates of the point at 6o'clock is (0,-5)
At 9o'clock the hour hand is on negative of x axis .The coordinate of the point at 6o'clock is(-5,0)
Answer:
c. 0.3421
Step-by-step explanation:
The computation of the probability of selecting the biased coin is shown below:
The probability of any coin selected is 1 ÷ 2
The probability in the case when the biased coin chosen & wins 1 ÷ 2 (1 - 0.74)
And, the win probability is 1 ÷ 2 (1 - 0.74) + 1 ÷ 2 (1 - 0.5)
Now the probability of biased or win is
= {1 ÷ 2 (1 - 0.74)} ÷ { 1 ÷ 2 (1 - 0.74) + 1 ÷ 2 (1 - 0.5)}
= 0.13 ÷ 0.38
= 0.3421
Hence, the correct option is c. 0.3421
Answer:
Slope: 2
The slope how much y increases when x increases by 1.
Step-by-step explanation:
1. Find the difference between both y-coordinates. (6)
2. Find the difference between both x-coordinates. (3)
Divide the difference between y and x. y/x=2
The slope is 2.
Answer:
Scale of 181: 1
Step-by-step explanation:
The first thing to do is to pass the feet by the meter, to work in the same units and thus create a consistent scale:
We know that one foot equals 0.3048 meters, therefore:
8 feet * 0.3048 meters / 1 foot = 2.4384 meters
So the scale would be:
443.2 / 2.4384 = 181.75
Which means that it is best to make a scale of 181: 1
Where 181 meters from the Empire State Building would equal 1 meter at home 0 181 inches would equal 1 inch at home
