Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
Step-by-step explanation:
A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.
A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.
In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.

Answer:
8
Step-by-step explanation:
We know that in 5 days they have travelled 2045 miles. This means that their per day average for travel is 2045/5=409 miles per day.
Now the distance left is 3272-2045=1227 miles.
And if we divide the average miles with the miles left, it gives us= 1227/409
=3
So, the total time taken for travel will be= 5+3=8 days
I guess this is the way to do it.
Answer:
CA=17
Step-by-step explanation:
From given picture we see that A and C are the mid points of sides QR and QS respectively.
We know that line joining mid points of the two sides of triangle is always half of the length of the third side.
So that means:
2*CA=SR
2(3x-1)=5x+4
6x-2=5x+4
6x-5x=4+2
x=6
plug value of x into CA=3x-1
CA=3*6-1=18-1=17
Hence final answer is CA=17
