Answer:
A square
Step-by-step explanation:
a) means what is the probability of P occurring once Q has occurred. That is 9/24 which is 3/8.
b) is 14/24 which is 7/12.
Please inform me if I gave you the correct answers :)
2 notebooks* ($20/ 5 notebooks)= $8.
(Note that the unit cancels out so you get the answer)
Final answer: $8~
Answer:
These types of questions are not daunting if you break it down. First look at "Five less than twice the value of a number."
"Twice the value of a number" is simply 2x.
"Five less" is simply -5, so for the first part we have (2x-5)
Next, analyze the second part. "Three times the quantity of four more than one half the number."
Looking at "Three times the quantity" simply means "3 times something".
"the quantity of four more than one half the number" is 4 + "one half the number" or 4 + (1/2)x.
So the second part is simply 3(4+x/2).
Finally we finish the entire equation, (2x-5) = 3(4+x/2) then solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x=34
Checking the left side, (2x-5) = 2(34) - 5 = 63.
Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.
