Step-by-step explanation:
if you don't even understand the question, this is also something you need to tell your teacher. it is his/her job to make you understand it.
a probability is always
desired cases / possible cases
so, if we pick a single student randomly, how many possible options do we have ?
we have 2+5+6+9 = 22 students (as the 4 categories in the table are mutually exclusive).
therefore, our possible cases to pick a student are 22.
now, how many of these 22 students represent our desired cases ?
male, who does not have an A : 9
so, the probability to pick a student who is male and does not have an A is
9/22 = 0.409090909...
Here is an example, if the graph hovers above the x-axis (k<0) then there will be no real solutions
For the 2 tabs on the table you subtract and get your answer. And for 3 and 4 you divide 90 and 55, 42 and 30. Then try to divide the other ones too :)
Answer: Some of the exponents were hard to see. Please check the answers carefully.
9. -18x^7
10. 6m^3n^2
11. 14a^6b^-4
12. 4a^12
13. x^8y^2
14. 8x^-6y^-15
15. Can't make out the exponents. Is there a minus sign in front of both exponents?
16. -432x^10y^4
17. 4x^3
18. 4b/5a^3
Step-by-step explanation:
You would draw a rectangle in a plane of squares, 34 squares width and 87 squares in length. To do this just draw 34 down, 87 to the side, 34 up, then 87 to the side to connect it.
