<u>Answer-</u>

<em>The necklace with 24 shells is longer than the necklace with 18 shells by 9 inches.</em>

<u>Solution-</u>

Length of each dentalia shell = 1.5 inches

Length of the necklace made with 24 shells = 24×1.5 = 36 inches

Length of the necklace made with 18 shells = 18×1.5 = 27 inches

The necklace with 24 shells is longer than the necklace with 18 shells by the amount of ,

= 36 - 27 = 9 inches

∴ The necklace with 24 shells is longer than the necklace with 18 shells by 9 inches.

( ∵ As the numbers are already rounded off or natural numbers, so we don't have to round them off or use the compatible numbers.)

False. In a coin, there are 2 possible out comes i.e. a head and a tail. if p is the probability of one side coming up, then the probability of the other side comin up will be q = 1 - p.

Therefore, if the probability of head coming up is 3/10, the probability of tail coming up will be 1 - 3/10 = 7/10.
