Y - (-4) = (5 - (-4))/(2 - (-1)) (x - (-1))
y + 4 = (5 + 4)/(2 + 1) (x + 1)
y + 4 = 9/3 (x + 1)
y + 4 = 3(x + 1)
y + 4 = 3x + 3
y = 3x + 3 - 4
y = 3x - 1
Answer:
mass = density · volume
Step-by-step explanation:
To find the mass of a given volume, multiply your given volume by the <em>density</em>. Often, density is given in grams per cubic centimeter. 1 cubic centimeter is the same as 1 milliliter.
Answer:
3.33
Step-by-step explanation:
Let x represents the number of dvds sold per day:
To complete the probability distribution table, you need to add all the probabilities given and deduct that to 1 so that you can get the probability of 5-9, applying what I have said:Probability of 5-9:= 1 - (0.1875+0.4375+0.1250) = 1 – 0.75= 0.2500
But the question is not asking for the probability of 5-9, but 5 or more. So deduct the .1875 to 1 since .1875 only represents 0-4.P(X>= 5) = 1 - 0.1875 = 0.8125
