nikdorinn [45]

Answer:

D.) 0.9990

Step-by-step explanation:

Given :

Number of questions = 10

True or False questions ; probability of success, p = 1/2 = 0.5

Using binomial distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Probability of getting atleast one correct answer :

P(x ≥ 1) = p(1) + p(2) +... P(x = 10)

Using a binomial probability calculator :

P(x ≥ 1) = 0.9990

What is the area of a sector with a central angle of 108 degrees and a diameter of 21.2 cm?
Rasek [7]

Answer:

105.84\ cm^2

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is

A=\pi r^{2}

we have

r=21.2/2=10.6\ cm ----> the radius is half the diameter

substitute

A=\pi (10.6)^{2}

A=112.36\pi\ cm^2

step 2

Find the area of a sector

Remember that

The area of the circle subtends a central angle of 360 degrees

so

using proportion

Find out the area of a sector with a central angle of 108 degrees

\frac{112.36\pi}{360^o}=\frac{x}{108^o}\\\\x=112.36\pi(108)/360\\\\x=33.708\pi\ cm^2

assume

\pi=3.14

substitute

33.708(3.14)=105.84\ cm^2
