Find the volume of the tank by using the equation V = l x w x h
Volume = 14 x 32 x 24 = 10,752 cubic feet
now calculate the number of gallons by dividing total cubic feet by 0.134:
10,752 / 0.134 = 80,238.81 gallons
now multiply the number of gallons by the weight per gallon:
80,238.81 x 8.33 = 668,389.287 pounds
rounded to nearest tenth = 668,389.3 pounds total
Answer:
a) 0.06
b) 0.778
Step-by-step explanation:
Let's suppose a community of 100 families just to facilitate the calculation.
30% of the families own a dog
Dog = 30% of 100 = 30
20% of the families that own a dog also own a cat = 20% of 30 = 6
27% of all the families own a cat = 27% of 100 = 27
So, 6 families own a dog and a cat.
As 30 families own a dog, [30 - 6 =] 24 families own only dogs
As 27 families own a cat, [27 - 6 = ] 21 families own only cats
See picture attached.
a) What is the probability that a randomly selected family owns both a dog and a cat?
P(dog and cat) = dog ∩ cat/total = 6/100 = 0.06
b) What is the conditional probability that a randomly selected family doesn't own a dog given that it owns a cat?
So, only cat/total cat
P (not dog|cat) = 21/27 = 0.778
There wound be a clean answer other than 72/100
Answer:
It hasn't got any real roots,because as you see there isnt left numbers.
