Answer:
not
Step-by-step explanation:
The square root of 8 is not the root of a perfect square, so it is irrational. Multiplying it by a rational number gives an irrational product.
-3√8 is irrational
Answer:
You can't use a uniform probability model because that would require each item to have an equal chance.
Explanation:
11/44 b (25%)
18/44 o (40.91%)
15/44 p (34.09%)
As you can see, they aren't an equal chance.
Answer:
width = 11
length = 25
Step-by-step explanation:
11 x 2 + 3 = 25
25 + 11 = 36
Answer:
The length of a 180° arc of a unit circle is π ≈ 3.14 units.
Step-by-step explanation:
Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to
... (180°/360°) × circumference = (1/2)×circumference
For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.
