Answer:
1245
Step-by-step explanation:
-Given the standard deviation is $9000 and the margin of error is $500.
-the minimum sample size at a 95% confidence level can be calculated using the formula:
Hence, the minimum sample size is 1245
*Since there's no data fromw which we are drawing our variables, we can manually input our parameters in excel and calculate as attached.
Answer:
Option 1 is correct.
Step-by-step explanation:
Given the equation
we have to choose the best statement describes the above equation.
→ (1)
As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.
⇒ Degree of above equation is 2.
hence, the given equation is quadratic equation.
The general form of quadratic equation is
In variable u: → (2)
Now, compare equation (1) with (2), we say that
The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).
Option 1 is correct.
