As we know that the area of a rectangle is -

length × Breadth

So, here length = (3n+1)

Breadth = (2n-5)

Area of rectangle
= (3n+1)(2n-5)

= 3n(2n-5)+1(2n-5)

= 6n² - 15n + 2n - 5

= 6n² - 13n - 5

Answer) Area of rectangle is 6n² - 13n - 5

Vilka [71]
Number of raptors in 2015: 234

% success: between 35% and 40%

Formula

% =: [number of success rescues / number of total rescues] * 100 =>

number of success rescues = % * number of total rescuess / 100

Number of success rescues:

a) 35 * 234 / 100 = 0.35 * 234 = 81.9

b) 40 * 234 / 100 = 0.40 * 234 = 93.6

Then, the number of raptor rescues that were succesfull was about 82 to 94.

The director of the library believes that 14% of the library's collection is checked out. If the director is right, what is the
Ksivusya [100]

Answer: 0.2643

Step-by-step explanation:

Let p be the population proportion and \hat{p} be the sample proportion .

As per given question , we have

p=0.14\\\\ \hat{p}=0.13\\\\ n=478

z-score : \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

z=\dfrac{0.13-0.14}{\sqrt{\dfrac{0.14(1-0.14)}{478}}}\\\\=-0.630087269176\approx-0.63

The required probability ( using z-table ):-

P(z

Hence, the probability that the proportion of books checked out in a sample of 478 books would be less than 13% = 0.2643
