In a recent survey, 30% indicated chocolate was their favorite flavor of ice cream. Suppose we select a sample of nine people and ask them to name their favorite flavor of ice cream.

(a) How many of those in the sample would you expect to name chocolate? (Round your answer to 2 decimal places.)

(b) What is the probability exactly five of those in the sample name chocolate? (Round your answer to 4 decimal places.)

(c) What is the probability five or more name chocolate? (Round your answer to 4 decimal places.)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

a = 11 : 4

b = 38

c = 1 for every 6

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
