Yes it is because if you round 14 to 15, and add 15 and 15 you get 30. Then do 30 times 3 to get 90. Round this to the nearest hundred and you get 100.

Answer:

90; 100 is a reasonable estimate

Step-by-step explanation:

Given,

The number of Stamps Julissa has = 15,

Also, the number of stamps Ethan has = 14

So, the total number of stamps both Julissa and Ethan have = 15 + 14

= 29

According to the question,

The number of stamps that Pawel has = 3 × the combined number of stamps both Julissa and Ethan have

= 3 × 29

= 87

≈ 90 ( nearest tens )

Also, the nearest hundred of 87 is 100,

Hence, 100  is a reasonable estimation,

SECOND option is correct.

Find the number of permutations of the first 9 letters of the alphabet, taking 4 letters at a time.
Vinil7 [7]

Solution-

First 9 letters of alphabet are- A,B,C,D,E,F,G,H,I

Total number of ways of selection of 4 letters from 9 alphabets = 9C4

=9!÷((4!).(9-4)!) = 9!÷(4!×5!) = (9×8×7×6)÷(24) = 126

The number of ways of arranging these 4 numbers = 4! = 24

∴ Total number of possible permutations = 9C4×4! = 126×24 = 3024

∴ option number 2 is correct.
