Answer:

  3042 in³

Step-by-step explanation:

The dimensions of the water are ...

  19.5 in long × 12 in wide × 13 in tall

The volume in cubic inches is ...

  V = LWH

  V = (19.5 in)(12 in)(13 in) = 3042 in³

_____

At 231 cubic inches per gallon, that's about 13.17 gallons.

Lottie buys a pack of 50 cans of lemonade.
malfutka [58]

Answer:

£15.7

Step-by-step explanation:

32 cans x 50P = 1600p

1600p to Pounds = £26.66 (1600 divided by 60)

Remaining cans = 18 (50 - 32)

18 cans x 20p = 360p

360p to Pounds = £6 (360 divided by 60)

£26.66 + £6 = £32.66

£32.66 (Profit) - £17 (Cost of cans) = £15.66

15.66 to 3SF = 15.7

Suppose you just purchased a digital music player and have put 9 tracks on it. After listening to them you decide that you like
ioda

a) consider the first song played . The probability of its being liked is 4/9.

And for second song, we have 3 liked songs and 8 remaining songs.

Hence probability of second being liked is 3/8.

Overall probability = (4/9)*(3/8) = 1/6 = 0.167 hence it is almost unusual.

b) First song being not liked is 5/9.

And for second song being not liked is 4/8.

Hence overall probability = (5/9)*(4/8) = 5/18.

c) To like exactly one of them, it has 2 possibilities. First song may be liked and second song disliked = (4/9)*(5/8) = (5/18)

First song may be disliked and second song liked = (5/9)*(4/8) = (5/18)

Hence overall probability = (5/18)+(5/18) = 5/9

d)  a)Probability of 2 songs liked by me with replacement means in both cases i have to select a song from 4 liked songs.

Hence probability = (4/9)*(4/9) = 16/81

b) probability of both being not liked by me is = (5/9)*(5/9) = (25/81)

c) probability of exactly one being liked = (4/9)*(5/9)+(5/9)*(4/9) = 40/81
