Answer:
there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.
the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%
the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%
the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%

Step-by-step explanation:
We have a graph given to us.
⇒ Take the points to form an equation!
<u>The points</u>
<u>Making an equation</u>
- Find the slope
- m = 1 - 6 / -2 - 4
- m = -5 / -6
- m = 5/6
- Take one of the two points and substitute in the equation :
- ⇒ y - y₁ = m (x - x₁)
- ⇒ y - 6 = 5/6 (x - 4)
- ⇒ y - 6 = 5x/6 - 10/3
- ⇒ <u>y = 5x/6 + 8/3</u>
- ⇒ or <u>6y = 5x + 16</u>

Answer:
r=3
Step-by-step explanation:
- The equation of a circumference is
. - Then , in this case
, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.
