Answer:
A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample
Step-by-step explanation:
In statistics we have to deal with populations and samples to carry out our studies. A population is a large group under consideration and the elements or members of the population have some common features or attributes. For example, all the school going kids in a certain town will be considered a population. Sample on the other hand is a subset(a part) of the population. For example, all school going kids in the town aged 5-6 years will be considered a sample.
The term Parameter and Statistic are very similar as they represent some numeric description. Parameter represents the data of the entire population, while statistic represents that data of a sample. An easy way to remember this is to match the initials i.e. Parameter for Population and Statistic for Sample.
Considering this, we can say the correct answer is:
A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample
Answer:
10y3 - 5y2 - 10x + 4

Equation at the end of step 2 :
Step 3 :
10y3 - 5y2 - 10x + 4
Simplify ————————————————————
2y - 1
Checking for a perfect cube :
3.1 10y3 - 5y2 - 10x + 4 is not a perfect cube
Final result :
10y3 - 5y2 - 10x + 4
————————————————————
2y - 1
Answer:
Let's solve your system of equations by elimination.
8x+9y=48;12x+5y=21
Steps:
Multiply the first equation by 5,and multiply the second equation by -9.
5(8x+9y=48)
−9(12x+5y=21)
Becomes:
40x+45y=240
−108x−45y=−189
Add these equations to eliminate y:
−68x=51
Then solve−68x=51for x:
−68x
/−68
=
51
/−68 (Divide both sides by -68)
x= −3
/4
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
8x+9y=48
Substitute
−3
/4
8x+9y=48:
8(
−3
/4
)+9y=48
9y−6=48 (Simplify both sides of the equation)
9y−6+6=48+6 (Add 6 to both sides)
9y=54
9y
/9 = 54
/9 (Divide both sides by 9) y=6
<em><u>Answer: x= −3
/4 and y=6</u></em>
