Total number of times she flipped a coin =200.
Total number of heads in the experiment=92
Total number of tails in the experiment=108
Therefore probability of the coun landing heads up in this experiment is 0.5
In the above experiment, the probability of the coin landing heads up is
P(H)= 92/200 = 0.46
In the above experiment, the probability of the coin landing tails up is P(T) = 108/200 = 0.54
The ratio obj represent the experimental probability of the coin landing heads up in this experiment
Therefore the correct option is 1.

Answer:
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
Step-by-step explanation:
If the length of a minute hand of a clock is 3.5cm, to find the angle it turns through if it sweeps an area of 48 cm, we will follow the steps below;
area of a sector = Ф/360 × πr²
where Ф is the angle, r is the radius π is a constant
from the question given, the length of the minute hand is 3.5 cm, this implies that radius r = 3.5
Ф =? area of the sector= 48 cm² π = 
we can now go ahead to substitute the values into the formula and solve Ф
area of a sector = Ф/360 × πr²
48 = Ф/360 ×
× (3.5)²
48 = Ф/360 ×
×12.25
48 = 269.5Ф / 2520
multiply both-side of the equation by 2520
48×2520 = 269.5Ф
120960 = 269.5Ф
divide both-side of the equation by 269.5
448.8≈Ф
Ф = 448.8°
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
