Answer:

There are 23.1% probability of flights getting delayed.

Step-by-step explanation:

Given:

Number of samples of flights selected = 1000

Number of flights arrived on time = 769

We need to find the probability of flight being delayed.

Solution:

Now we will first find the number of flights which are delayed.

number of flights which are delayed can be calculated by subtracting Number of flights arrived on time from Number of samples of flights selected.

framing in equation form we get;

number of flights which are delayed = 1000-769 =231

Now we will find the probability of flight being delayed.

probability of flight being delayed can be calculated by dividing number of flights which are delayed from the Number of samples of flights selected  and then multiply by 100.

framing in equation form we get;

probability of flight being delayed = \frac{231}{1000}\times 100 = 23.1\%

Hence There are 23.1% probability of flights getting delayed.

An 8-sided die is formed when two square pyramids are attached by their bases. The perimeter of the base shape is 6 centimeters.
lawyer [7]

Answer:

7.5cm²

Complete question:What is the surface area of the 8-sided figure?

Step-by-step explanation:

Consider the half of the 8-sided die i.e the pyramid ABCDE:

As the base is 6 of the perimeter, so each side of the base is 6/4=3/2

Now, the distance between the tallest points is 2 cm, so the height of Pyramid ABCDE is 1 cm.

Considering the right triangle EOM:

EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is 

\sqrt{1+ ( \frac{3}{4} )^{2} }=  \sqrt{1+ \frac{9}{16} }= \sqrt{ \frac{25}{16} }= \frac{5}{4}   (cm)

5. So side EBC has area  

\frac{1}{2}BC*EM=  \frac{1}{2}* \frac{3}{2}* \frac{5}{4}= \frac{15}{16}

6. The total area is 8*Area(EBC)=8* \frac{15}{16}= \frac{15}{2}=7.5 ( cm^{2} )
