Answer:
Each friend will get 18 sea shells.
Step-by-step explanation:
Given:
Rudy has white sea shells = 10
Rudy has pink sea shells = 23
Rudy has brown sea shells = 21
Number of friends = 3
Rudy divides the sea shells into equally between three friends.
We need to find how many sea shells each friend can get.
Now first we find the total number sea shells.
Total number of sea shells = white sea shells + pink sea shells + brown sea shells = 10 + 23 + 21 = 54
Now to find number of sea shell each friend can get we will divide total number of sea shell with number of friends.
number of sea shell each friend can get = 
Hence each friend will get 18 sea shells.
Answer:
The estimate is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 522
The sample proportion of students would like to talk about school is 
Given that the confidence level is 90 % then the level of significance can be mathematically evaluated as
Next we obtain the critical value of 
from the normal distribution table, the value is
Generally the margin of error can be mathematically represented as
=> 
=> 
Generally the estimate the proportion of all teenagers who want more family discussions about school at 90% confidence level is
substituting values
