tiene que sacar la raiz nena
A) 0.8
B) 0.24
C) 0.56
D) 0.44
For A, since 1 in 5 is dry, 4 in 5 are not; 4/5 = 0.8
For B, we know that 30%, 0.3, of the ones that are not dry are contaminated:
0.3(0.8) = 0.24
For C, 100%-30%=70% of wells that are not dry are not contaminated; 0.7(0.8) = 0.56
For D, she will either have contaminated water or no water:
0.24+0.2 = 0.44
The answer to the question
Answer:
x^2 - (4+13i)^2
Step-by-step explanation:
This product has the form (a-b)(a+b), which is a 'special product' equal to a^2 - b^2. Following this pattern, [x-(4+13i)][x-(4+13i)] = x^2 - (4+13i)^2. The 2nd term could be expanded if desired, but the above result is the most compact one possible.
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction
This is the order of how to solve the problems. For this problem, we can start with parentheses since it has that in this equation.
5 x 6 ÷ (5)
The next step is to do Multiplication.
30 ÷ 5
Finally Division.
6
This is your final answer.
Hope that helps!
