Answer:
hope this helps!
Step-by-step explanation:
You have to divide:
1.9x10^-8 ÷ (4.2x10^-13)
= appr .45 x 10^5
= .45 x 100000
= appr 45,000 times as large

Answer:
a)
b)
Step-by-step explanation:
For this case our sample space is the 5 letters given:
And we want to find the number of three letter words can be made from the sample space with some conditions
Part a
For this case the repetition is allowed so then each time we will have 5 possibilites in order to select one letter so if we use combinatories we have:
So then we will have 125 possible combinations of 3 words letters with the 5 provided
We need to remember that
Part b
For this case the repetition is not allowed so then the possible number of possibilities are:
So then we will have 60 possible combinations of 3 words letters with the 5 provided
Answer:
the percentage is 55/100*100=55%
Step-by-step explanation:
the segment of the square is 40/4=10 cm
so the area of the square is 10^2=100cm^2
the shaded area = the area of the square - the sum of the areas of the triangles inside the square
100- (10*6/2+10*3/2)=100-(30+15)=55 cm^2
