Answer:4x^3-2x^2+20x-10
Step-by-step explanation:
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.
Answer:
Not sure but 2 would be the same as 1 so 39.5 and 3 and 4 would be 50.5
Step-by-step explanation:
1 and 3 make a right angle and so does 4 and 2 so all I did was subtract 39.5 from 90 since a right angle=90 degrees
Answer:
Your answer is 6.4 kilograms :D
Step-by-step explanation:
The Pythagorean theorem formula for a triangle is A^2 + B^2 = C^2 where A and B are the sides and C is the hypotenuse.
The sides of the triangle shown are AB and BC and the hypotenuse is AC,
so the correct answer would be:
(AB)2 + (BC)2 = (AC)2, because 25 + 144 = 169
