Answer:

$\mathrm{11.\:}\frac{176}{5}\pi\:\mathrm{ft^2},\\\\\mathrm{12.\:}\frac{1573}{18}\pi\:\mathrm{mi^2},\\\\\mathrm{13.\:}\frac{269.08}{24}\pi\:\mathrm{km^2}\\\\\mathrm{14.\:}\frac{252.05}{6}\pi\:\mathrm{cm^2}\\\\\mathrm{15.\:}\frac{870.75}{72}\pi\:\mathrm{yd^2}\\\\\mathrm{16.\:}\frac{5953.48}{36}\pi\:\mathrm{m^2}$

Step-by-step explanation:

The area of a sector can be given as:

$\frac{c^{\circ}}{360^{\circ}}\cdot r^2\pi$ , where $c$ is the angle of the sector in degrees.

Problem 11:

$\frac{88^{\circ}}{360^{\circ}}\cdot 12^2\pi=\fbox{$\frac{176}{5}\pi\:\mathrm{ft^2}$}$

Problem 12:

$\frac{260^{\circ}}{360^{\circ}}\cdot 11^2\pi=\fbox{$\frac{1573}{18}\pi\:\mathrm{mi^2}$}$

Problem 13:

Convert radians to degrees:

$\frac{7\pi}{12}\cdot\frac{180}{\pi}=105^{\circ}$

$\frac{105^{\circ}}{360^{\circ}}\cdot 6.2^2\pi=\fbox{$\frac{269.08}{24}\pi\:\mathrm{km^2}$}$

Problem 14:

Convert radians to degrees:

$\frac{5\pi}{3}\cdot \frac{180}{\pi}=300^{\circ}$

$\frac{300^{\circ}}{360^{\circ}}\cdot 7.1^2\pi=\fbox{$\frac{252.05}{6}\pi\:\mathrm{cm^2}$}$

Problem 15:

$\frac{215^{\circ}}{360^{\circ}}\cdot 4.5^2\pi=\fbox{$\frac{870.75}{72}\pi\:\mathrm{yd^2}$}$

Problem 16:

Convert radians to degrees:

$\frac{13\pi}{18}\cdot\frac{180}{\pi}=130^{\circ}$

$\frac{130^{\circ}}{360^{\circ}}\cdot 21.4^2\pi=\fbox{$\frac{5953.48}{36}\pi\:\mathrm{m^2}$}$

Some researchers claim there is an association between taking vitamins and gaining weight. They took a random sample of people l

netineya [11]

Answer:

The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47

Step-by-step explanation:

Has Gained Weight Has Not Gained Weight

Does not take vitamins 52 19

Takes one vitamin per day 35 49

Takes more than one vitamin per day 72 80

We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day

A= he or she has gained weight

B=he or she takes more than one vitamin per day

$P(A|B)=\frac{P(A \cap B)}{P(B)}$

$A \cap B = 72$

B = 72+80=152

So, $P(A|B)=\frac{72}{152}=0.47$

So, Option C is true

Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47

Carefully read the following sentence: “Although the curators disagreed in the beginning, they finally agreed to place the oil p

Nuetrik [128]

The phrase "alongside the drawing by Michelangelo" is a A. prepositional phrase. The whole phrase starts with the preposition "alongside," which is why it is a prepositional phrase. Given that there are no verbs or adverbs in this phrase, it certainly cannot be a participial, verbal, or adverbial phrase. This is because participles and verbals refer to verbs, and adverbials to adverbs, which do not exist in this phrase.
