Im having trouble with a answer its about probability P(F) but I dont understand it that much

Step-by-step explanation:

This book doesn't really explain this specific probability question clearly. The circle has 10 small triangles. F is one triangle. We can say that F occurs every 10 small triangles so the ratio would be:

For the second one, we can have D or B, which both have 1 triangle each. We can say that D or B can have 2 triangles out of 10 so the ratio would be:

We can simplify 2/10 to 1/5.

For the third one, we have 3 vowels. So the ratio would be

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
