Determine whether the underlined number describes a population parameter or a sample statistic. Explain your reasoning. Sixty-five of the 93 passengers aboard an airship survived an explosion Choose the correct statement below.
A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
B. The number is a population parameter because it is a numerical description of all of the passengers that survived.
C. The number is a population parameter because it describes the people in the airship, which is a subset of all people.
D. The number is a sample statistic because it describes the people in the airship, which is a subset of all people.
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.
The average depth of the Arctic Ocean is 4 x 10^3 feet while the average depth of the Atlantic Ocean is 1.2 × 10^4 feet. How many times more deep is the Atlantic Ocean than the Arctic Ocean?

3 times as deep.
Step-by-step explanation:
(1.2 x 10^4) / (4 x 10^3)
= 0.3 x 10^1
= 3

Answer:
Step-by-step explanation:
Part A
Area of a rectangle = length x width
Garden area = 7 3/4 x 2 2/3
= 31/4 x 8/3
= 62/3
= 20 2/3 square feet
Part B
5/8 of the area = 62/3 * 5/8
= 31*5 / 3*12
= 155 / 36
= 4 11/36
The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.

A ternary string is an ordered string of characters which consists of digits (0,1, or 2). For example, the ternary string 2122010 consists of exactly 2 zero's, 2 one's and 3 two's; another ternary string meeting these conditions is 0021221. How many ternary strings are there with exactly 4 zero's, 3 one's and 6 two's?
The number of ternary strings is an illustration of combination
There are 6227020800 ternary strings with exactly 4 zero's, 3 one's and 6 two's
How to determine the number of stringsAssume the zero's, one's and the two's can take any position in the string
For a ternary string of exactly 4 zero's, 3 one's and 6 two's, the number of characters in the string is 13.
The first 4 zeros can take any of the 13, 12, 11 and 10th positions
The next 3 ones can take any of the 9, 8 and 7th positions
The remaining 6 twos can take any 6! positions
So, the number of strings is:
Strings = 13* 12 * 11 * 10 * 9 * 8 * 7 * 6!
Evaluate the products
Strings = 6227020800
Hence, there are 6227020800 ternary strings with exactly 4 zero's, 3 one's and 6 two's
