Answer:
Proportion = 0.6 or 60 %
Step-by-step explanation:
Given:
- The obtained 95% confidence interval of a sample of adults rooting for North High:
(0.52 , 0.68)
- Sample size n = 150
Find:
What proportion of the 150 adults in the survey said they were rooting for North High School?
Solution:
The proportion of adults rooting for North high corresponds to the mean value of interval, as follows:
Proportion = ( 0.52 + 0.68 ) / 2
Proportion = 0.6 or 60 %

Answer:
Final answer is 13.
Step-by-step explanation:
Given expression is
-k+h+kh
We also have been given values of h and k as:
k=-5 h=-2
to simplify the given expression, we just need to plug the given values of k=-5 and h=-2 into -k+h+kh
-k+h+kh
Hence final answer is 13.
Answer:
Step-by-step explanation:
Let the amount of money received for the accessories = x
Then the Saw would be 10x
The total is 10x + x = 759
11x = 759 Divide both sides by 11
x = 759 / 11
x = 69 dollars.
The saw was 10 times this amount = 10 * 69 = 690
Check
690 + 59 = 759
Answer:
g(x)=x² -3
Step-by-step explanation:
Vertical and horizontal translations are the displacements of a function in the coordinate system (x, y). By transferring the graphical representation of a given function, we obtain representations of related functions. The graph of the translated function will always be the same as the original.
When performing a vertical translation of a function, the graph will move from one point to another determined point in the direction of the "y" axis, that is, up or down.
So, the algebraic expression of the parabola that results from moving the parabola f (x) = x² vertically is f (x) = x² + q
-
If q> 0, the parabola moves q units up.
-
If q <0, the parabola moves q units down.
So the vertex of the parabola is at the point (0, q).
So if the function f (x) = x² is translated 3 units down, the function g (x) will be:
<u><em>g(x)=x² -3</em></u>
