A plan for a park has a rectangular plot of wild flowers that needs to be enclosed by 54 feet of fencing. Only three sides need

saw5 [17]

The largest area possible for the garden is 364.5 ft²

The width that will produce the maximum area is 13.5 ft

The length that will produce the maximum area is 27 ft

<h3>Area of a rectangle:</h3>

area = lw

where

l = length

w = width

Only three sides need to be enclosed because one side is bordered by the parking lot. Therefore,

perimeter = l + 2w

54 = l + 2w

l = 54 - 2w

Therefore,

area = (54 - 2w)w

(54 - 2w)w = 0

w = 0 or 27

average = 27 /2 = 13.5

Hence, the max area is at w = 13.5 meters

Therefore,

l = 54 - 2(13.5) = 27 ft

length = 27 ft

width = 13.5 ft

Therefore,

area = 27 × 13.5 = 364.5 ft²

Therefore, the largest area possible for the garden is 364.5 ft²

Suppose that a particular candidate for public office is in fact favored by 48% of all registered voters in the district. a poll

Nutka1998 [239]

Given that <span>a particular candidate for public office is in fact favored by 48% of all registered voters in the district, thus p = 0.48

If </span><span>a polling organization will take a random sample of 550 voters, i.e. n= 550.

</span>T<span>he approximate probability that p̂ will be greater than 0.5 is given by:

$P(\hat{p}\ \textgreater \ 0.5)=1-P(\hat{p}\leq0.5) \\ \\ =1-P\left(z\leq \frac{0.5-0.48}{\sqrt{ \frac{0.48(1-0.48)}{550} }} \right) \\ \\ =1-P\left(z\leq \frac{0.02}{\sqrt{ \frac{0.2496}{550} }} \right)=1-P\left(z\leq \frac{0.02}{0.0213} \right) \\ \\ =1-P(z\leq0.9388)=1-0.82609=0.1739$

Therefore, </span><span>the approximate probability that p̂ will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election is 0.1739.</span>
