According to the graph, which depicts a parabola, we can determine that the function will be quadratic. First, we identify the zeros as x=2 and x=4. Next, we can form the function using a point to solve for 'a'. For instance, at x=3 and y=-3, we can find 'a.' Plugging back into the equation, we can perform necessary multiplications to reach the final function.
Response:
e. 545
Detailed explanation:
In a survey sample containing n individuals, with a success probability of
, and a confidence level of
, the ensuing confidence interval for proportions is established.

Wherein
z denotes the z-score corresponding to a probability value of
.
For this scenario, we find:
The estimate averages the two bounds. Thus 
95% confidence level
Consequently, z represents the z value corresponding to the p-value of
, hence
.
The lower boundary of this interval is:

In this query, L = 0.82. Therefore






Thus, the accurate response is:
e. 545
The number of layers is calculated as 2^7 = 128. The overall thickness is then 128 multiplied by 0.1, resulting in 12.8 mm. I hope this information is useful.
By establishing a coordinate system where positive x is east and positive y is north, this can be addressed through vector addition.
A = <40cos(45), 40sin(45)>
B = <-60cos(60), 60sin(60)>
C = <0, -50>
R = A + B + C yields <-1.72, 80.25>
Thus, the necessary vector to return him home is -R.
Resulting in <1.72, -80.25>
I trust this response has been beneficial. Thank you for your question here. We look forward to addressing more of your inquiries in the future. Wishing you a pleasant day!
