Answer:

Option A - 17%

Step-by-step explanation:

Given : A dart is thrown at The board shown. it hits the board at a random point.

To find : The probability that it will land in the shaded region. round to the nearest percent?

Solution :

First we find the total area of the circle,

Let r be the radius of the circle

So, Area of the circle is A=\pi r^2

Now, Shaded region is with angle 60°.

The area of shaded region is A_s=\frac{60}{360}\times\pi r^2      

The probability that dart will land in the shaded region is

\text{Probability}=\frac{\text{Shaded area}}{\text{Total area}}      

\text{Probability}=\frac{A_s}{A}    

\text{Probability}=\frac{\frac{60}{360}\times\pi r^2}{\pi r^2}

\text{Probability}=\frac{60}{360}    

\text{Probability}=\frac{1}{6}    

\text{Probability}=0.1666    

Into percentage, P=16.66% ≈ 17%.

Therefore, Option A is correct.

Suppose the same quantity is measured but with a more precise method giving an average and standard deviation of 15.0 ± 2.5. how
abruzzese [7]

To solve this, we use the z test.

The formula:

z = (x – u) / s

where x is sample value = 20, u is the mean = 15, and s is the standard deviation = 2.5

z = (20 – 15) / 2.5

z = 2

Since we are looking for values greater than 20, this is right tailed test. We use the standard distribution tables to find for P.

P = 0.0228

 

Therefore:

number of students = 100 * 0.0228 = 2.28

 

<span>2 to 3 students will get greater than 20 measurement</span>
