Answer:

The answer is below!!

Step-by-step explanation:

The formula used to find the area of a circlular sector - a pie-shaped part of a circle. ... π. 4. 2. ·. 86. 360. = 12.01. What the formulae are doing is taking the area of the whole ... So for example, if thecentral angle was 90°, then the sector would have an area equal to one ... r is the radius of the circleof which the sector is part.

Hope I Helped!!

Answer:

area of entire circle = 84 in²

Explanation:

\sf \dfrac{\theta}{360} *\pi *r^2 = Area \ of \ sector

===========

\sf \rightarrow  \dfrac{60}{360} *\pi *r^2 = 14

\sf \rightarrow \dfrac{1}{6}\pi *r^2 = 14

\sf \rightarrow r^2 = \dfrac{14*6}{ \pi}

\sf \rightarrow r = \sqrt{\dfrac{84}{ \pi} }

\sf \rightarrow r = 5.17\ in

Area of circle:

\sf \pi r^2

=====

\hookrightarrow \sf \pi (5.17)^2

\hookrightarrow \sf 84\ in^2

The city of Raleigh has 10400 registered voters. There are two candidates for city council in an upcoming election: Brown and Fe
iVinArrow [24]

Answer:

Step-by-step explanation:

Hello!

a) The population of interest is the registered voters of the city of Raleigh.

b) This population is finite and its size is 10400 voters.

c) The sample was taken by making a telephone poll, calling 400 registered voters.

d) The sample size is n= 400 voters

The number of people that answered they'd vote for Brown are 151, so the sample proportion of voters that would vote for bron is:

p= 151/400= 0.3775 ≅ 0.38

e) To know how many people is expected to vote for Brown based on the results of the telephone poll you can do the following calculation:

10400*0.38= 3952

Based on the information obtained from the sample, it is expected that only 3952 voters will vote for Brown.

There are 7 animals a farmer's field.
sergey [27]

Answer:

2 cows and 5 chickens.

Step-by-step explanation:

NOTE: This will be solved using simultaneous equations.

Let x = cows and y = chickens

1. form two equations

4x + 2y = 18 ... (1)

x + y = 7 .... (2)

2. make y (or x) the subject of one equation

x + y = 7

y = 7 - x ... (3)

3. Substitute (3) into (1)

4x + 2( 7 - x) = 18

4. solve for x

4x + 14 - 2x = 18

2x = 4

x = 2

5. Now substitute x value into equation (2)

x + y = 7

2 + y = 7

y = 5

∴ cows (x) = 2

chickens (y) = 5
