The answer should be 0.40(1,125)=450
Answer: 1
Step-by-step explanation: Whenever you take the power of a power, the find the answer you can multiply the two exponents, for example:
(x^3)^4 = x^12
We will use that here.
a^8a^6 = a^14
((a^14)^1/7) = (a^2)/a^2
Our answer is 1
30 = 80*t
t = 30/80 = 3/8 hr
3/8 hr * 60 min/hr = 180/8 = 22.5 min
Answer:
A = choosing a red marble
B = choosing a green marble
Probability of A happening = P(A) = 5/(3+5+4) = 5/12
Probability of B happening = P(B) = 4/(3+5+4) = 4/12
Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12
The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).
Answer:
Step-by-step explanation:
x =(7-√193)/18=-0.383
x =(7+√193)/18= 1.161
