Answer:
Step-by-step explanation:
Prob at each second, a mosquito lands on your neck =0.5
Prob it bites/it lands = 0.2
Prob it does not bite/it lands = 0.8
Hence in one second prob for getting a bite = 
i.e. 1/100 chance of getting bitten in one second
In 100 seconds number of bites 
Expected time between successive bites = 100
Bidmas, division before addition3x(3+12/3)-4 = 3x(3+4)-4 = 21-4 = 17
It would be 50 percent or .5 the chances of odd would be 3/6 so 3/6*3/6 would be half of each dice. so 50% i believe
Answer:
The distance between the two points is approximately 11 units
Step-by-step explanation:
Here, we are to give the distance between the given two points to the nearest whole number;
To calculate the distance, we shall be using the distance formula;
D = √(x2-x1)^2 + (y2-y1)^2
(x1,y1) = (5,6)
(x2,y2) = (1,-4)
D = √(1-5)^2 + (-4-6)^2
D = √((-4)^2 + (-10)^2
D = √(16+100)
D = √(116)
D = 10.77 units which is approximately 11 units
Answer:
22years
Step-by-step explanation:
The sum of ages of people in the room is 40 * 5= 200
[ Remember mean = total ahead of people/ number of people]
Let the age of the 6th person be X
200+x. / 6 = 37
200 + x = 37 * 6 = 222
x = 222- 200 = 22
