Answer:
1
Step-by-step explanation:
The range is the difference between the largest and smallest values.
range = 9 - 2 = 7
If 2 is replaced by 3 then 3 becomes the smallest value and
range = 9 - 3 = 6
That is the range decreases by 1
Answer:
Step-by-step explanation:
The sum of those numbers is 14. Let's divide 14000 by 14 to get the number of parts (each part will be an investment in dollars) and we get 10,000. So if a person invests 2 parts, he invests 2(10,000). A person that invests 5 parts invests 5(10,000), and likewise for the person investing 7 parts: 7(10,000). That gives us 20,000 + 50,000 + 70,000 = ?
(140,000)
The difference in investment between the largest and the smallest is 50,000
Your answer is 4x^2+7x-10
Consider the following sets of sample data: A: $29,400, $30,900, $21,000, $33,200, $21,300, $24,600, $29,500, $22,500, $35,200,

Answer:
CV for A = 21.8%
CV for B = 15.5%
Step-by-step explanation:
The formula for coefficient of variation is:
CV = Standard Deviation / Mean
So,
For A:
Mean = Sum/No. of items
= 391300/14
=$27950
and
SD = $6085.31
CV for A = 6085.31/27950 * 100
=21.77%
Rounding off to one decimal
CV for A = 21.8%
For B:
Mean = Sum/No. of items
= 43.58/11
=3.96
and
SD = 0.615
CV for B = 0.615/3.96 * 100
=15.53%
=15.5% ..
Answer:
The population is all 600 members of the health club
Explanation:
50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.
