Answer:
16, 100
Step-by-step explanation:
A perfect square is a number that can be achieved by multiplying a number by itself.
Example: 100 = 10 x 10, so it is a perfect square
2 is not a perfect square because it has no factors that can be multiplied with each other to equal 2. An easy way to check is to use the square root function on your calculator.
If the result is a whole number then it's a perfect square.
Answer:
not a linear equation
Step-by-step explanation:
its a quadratic equation bcz whenever the power of variable exceeds 1 it is not a linear equation then. even if we plot a graph by assuming values of x we will see a curve is forming hence not a linear equation
Answer:
The interpretation is that we are 90% sure that the true average salary of the district is in this interval.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
The 90% confidence interval for the average salary of the district is [41500,49750].
This means that we are 90% sure that the true average salary of the district is in this interval.
This is even function because
1)the ends are looking in one side, both are up
2)You can see that it has line symmetry y
3) for any point
f(x)=f(-x)
f(1)=-6
f(-1)=-6
Answer:
x = -5q
