A random sample of 1,500 couples was asked the question, "How many children presently reside in your household?" Number of Children Frequency 0 325 1 212 2 660 3 151 4 68 5 or more 84 What number of children occurred the least frequently? Calculate this percent. (2 points) a 0, 21.67% b 0, 11.75% c 5 or more, 5.6% d 4, 4.53%

d. 4, 4.53%

Step-by-step explanation:

Given table :

Number of Children                 Frequency

0                                                      325  

1                                                       212

2                                                       660

3                                                       151

4                                                       68  ← Least frequency

5 or more                                         84

Total                                 =            1500

or Sample size of couples = 1500

The number of children occurred the least frequently = 4 [Minimum frequency is 68 at number of children=4]

Percentage =

Hence, the correct answer is d. 4, 4.53%

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
