Answer: P(mean x<18.1077) = P(z< -2.67) = 0.0038
Step-by-step explanation:
Value of Z for 18.1077 = (18.1077 - 19.5)/0.5209 = -2.67

Answer:
Step-by-step explanation:
You can multiply -3 by 4 and then multiply the result of that by 5, or you could write -3, 4 and 5 in other orders (6 possible orders) and obtain the same result.
I would multiply (-3) by 4, obtaining -12, and then multiply this -12 by 5, obtaining -60. But I could also multiply 5 by 4, obtaining 20, and then multiply this 20 by -3, obtaining the same -60.
What I have described here are the commutative and associative properties of multiplication.
