An example would be 1/3 as an exact answer and 0.33 as an approximate answer because 1/3 = 0.333..... - a recurring decimal where there are an infinite number of 3's. 0.33 would be correct to the nearest hundredth.
Radicals are exact answers :- like √2 , √5 . Approximate value for √2 is 1.414
Answer:
Step-by-step explanation:
4(2y -8) + y = 13
8y - 32 + y = 13
9y - 32 = 13
9y = 45
y = 5
x = 2(5) - 8
x = 10 - 8
x = 2
(2, 5)
Answer:
B. x=7
Step-by-step explanation:
(2x+5) = (x+12)
2x = x+7
x=7
A particular country has 60 total states. if the areas of all 60 states are added and the sum is divided by 60, the result is 212 comma 469 square kilometers. determine whether this result is a statistic or a parameter.
Answer: Before solving the given question, let us understand what the parameter and statistic is:
Parameter: Parameter is a number that summarizes data for an entire population. Like Population mean
Population standard deviation 
Statistic: Statistic is a number that summarizes data for a sample. Like sample mean
sample standard deviation
.
From the given information, we can clearly see that given characteristic describes the population.
Therefore, the option d is correct
d. the result is a parameter because it describes some characteristic of a population. is correct.
