Answer:
- 6r³.
Step-by-step explanation:
Here, we have to find the product of r², - 3 and 2r.
Now, the product is, P = (r²)(- 3)(2r)
⇒
{Seperating each terms as the terms are in product form}
⇒
{Using the property of exponent that }
⇒ P = - 6r³ (Answer)
Answer:
hello your question is incomplete below is the missing parts of the question
answer : K = 80
Step-by-step explanation:
P [ x ≤ 1 ] < 0.1
determine how large k have to be
note : n = k
sample proportion = 0.01
E = 0.05 - 0.01 = 0.04
applying this formula below
E =
0.04 = 1.645 make n subject of the equation
n = 80.3353
hence the value of K ≈ 80
