only the first statement is true - it is the experimental probability. the rest is incorrect: the ratio is not the number of trials; the theoretical probability should be 0.5 (for unbiased coins); ratio never represents a number of occurences.

Answer:

The correct option is 1.

Step-by-step explanation:

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

Theoretical probability of the coin landing heads up in this experiment is 0.5.

In the above experiment, the probability of the coin landing heads up is

P(H)=\frac{92}{200}=0.46

In the above experiment, the probability of the coin landing tails up is

P(T)=\frac{108}{200}=0.54

The ratio  represents the experimental probability of the coin landing heads up in this experiment.

Therefore the correct option is 1.

The length of a rectangular garden is 8m greater than twice the width the area of the garden is 280m^2 what is the width of the
yarga [219]

Step-by-step explanation:

Given :-

The length of the garden 8m greater than 2 times the width.

Area of the garden is 280 m²

Let us consider the length as x and width as y.

Sp, we can day length as :-

x = 8 + 2y ---(1)

Now, we know that:-

Area of Rectangle = Length × Breadth

280 = x * y

We can replace the value of x now,

280 = y × ( 8 + 2y)

280 = 8y + 2y²

2y² + 8y - 280 = 0

y² + 4y - 140 = 0

Factorise it.

(y -10)(y + 14)

Cancelling -ve value, we get the width as 10 metres.
