Answer:

40.6 units

Step-by-step explanation:

Arc length is given by the formula ...

s = rθ

where θ is the measure of the central angle in radians.

There are 2π radians in a circle (360°), so π radians in 180°. That can be used to convert the central angle ADB to radians for use in the formula.

∠ADB = 360° -194° = 166°

∠ADB = 166° = (166/180)π radians = 83π/90 radians

Then the arc length AB is ...

length AB = (14)(83π/90) ≈ 40.561 units

The length of arc AB is about 40.6 units.

It would be
y=(-16*-1)
which would then be
y=16
so the answer would be

Your little brother just learned how to flip and catch a coin. He believes that by catching the coin in mid-air, he can influenc

coldgirl [10]

<h2>Answer explanation:</h2>

If a coin is fair then it has two faces , one is heads and the another is tails.

The probability getting any favorable outcomes is given by the formula :-

$\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}$

So the factor effecting probability is just the number of favorable outcomes and total outcomes.

If a coin is tossed then the probability of getting heads will be :-

$P(H)=\dfrac{1}{2}=0.5=50\%$

To get heads always this should be 1 , which can be happen if number of favorable outcomes is equal to total outcomes.

i.e. Number of heads = Number of total outcomes, this means coin should be biased.

Catching the coin in mid-air can never be a factor for this.

Therefore, the little brother's theory is false.
