2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
-128y^2 x y^1 +2 = -128y^3
Answer:
Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Step-by-step explanation:
Number of red socks = 2
Number of white socks = 6
Number of blue socks = 4
Total socks in drawer = 2+6+4 = 12
The formula used to calculate probability is: 
We are given you draw out a sock, return it, and draw out a second sock.
We need to find the probability that the first sock is blue and the second sock is red?
Using formula:
Probability that first sock is blue = 4/12 = 1/3 = 0.33
Probability that second sock is red = 2/12 = 1/6 = 0.16
So, Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
So a day is 24 hours
24/6=4
4*5=20
so they spend 20 hours a day sleeping
here’s a full on equation
(24/6)*5
