402% as a percent and 4.02 as a decimal. Its Friday so sorry if im wrong
We can't really factor it, because it's already simplified. We only need to add...
Have a nice day! :)
Tetrahedron has 4 faces so it's a pyramid, dodecahedron is 12 faces, octahedron is 8 faces, icosahedron has 20 faces. Easiest way I know to classify them
<h3>
Answer: B) 47%</h3>
Work Shown:
A = event that the person has math degree
B = event that the person has a computer science degree
P(A) = 0.23, since 23% of the people have a math degree
P(B) = 0.31, similar reasoning as above, just different number
P(A and B) = 0.07
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.23 + 0.31 - 0.07
P(A or B) = 0.47
The decimal value 0.47 then converts to 47% after moving the decimal 2 spots to the right.
There's a 47% chance that we pick someone who has a math degree or a computer science degree (or both).
It might help to set up a venn diagram to see why that formula above works.
Answer:
C. 31
Step-by-step explanation:
3000 there are 3-4 errors
If we first divide 24,000 by 3,000, will get 8
then since there a error for each 3,000 books, we do 8 x 4 = 32 and 8 x 3 = 24
32 (8 x 4) the max amount of printing errors
24 (8 x 3) the minimum amount of printing errors
So we should expect 24-32 printing errors
Only answer between the numbers is c. 31
