Answer:

  • length: 8
  • end points: (-8, 1), (0, 1)

Step-by-step explanation:

In the quadratic form ...

  (x -h)² = 4p(y -k)

The value 4p is the length of the latus rectum. It also tells the distance between the vertex (h, k) and the focus (h, k+p).

<h3>Application</h3>

The value of 4p is given as 8. This means p = 8/4 = 2.

The length of the latus rectum is 8.

The end points of the latus rectum have the same y-value as the focus:

  y = k +p = -1 +2 = 1

The end points of the latus rectum have x-values that are h±2p.

  x = h ± 2p = -4 ± 2·2 = {-8, 0}

The end points of the latus rectum are (-8, 1) and (0, 1).

The Dallas Morning News is running a series of articles to see if the residents of Dallas still support the Mayor’s decision to
erastova [34]

<u>Answer and Step-by-step explanation:</u>

A+B only 10% = 1250 / 2 \times 1-2 = 0

1250 / 76=x 1.6 \pm(+1=2.5 \%) 90 \% \text { vote }=1226

95%=1302  

99% = 1377  

5% = 1188  

2.5% = 1169

A= deduct this from sample size B it is usually 5 of the vote% so in comparison would not hinder the negative we deduct 1 from the 5%. B. Margin of error is 2.5% deduction comparison was Mayor was asking for a negative outcome with a positive vote. which is biased alone. Loss of confidence due to margins.
