Rewrite as improper fractions 3 2/3 is (3*3+2)/3=11/3 and 14 2/5 is (5*14+2)/5=72/5 product means multiply so multiply the numerators and then denominators Numerators 11*72=792
denominators 3*5= 15 so then the answer is 792/15 = 52 12/15 =52 4/5
Answer:
A= 50
Step-by-step explanation:
Very interesting to see!
x= -1
and the both angles are equal!
<span>If we assume that T does not change, then PV = k.
If this is true, then P1V1 = P2V2 (Boyle's Law)
P1 = 1 atm (standard pressure)
V1 = 1 L
P2 = ?
V2 = .473L
P2 = 2.11 atm</span><span>

Answer:
What is the Q.?
Step-by-step explanation:
9514 1404 393
Answer:
b. 255.5 to 499.5
Step-by-step explanation:
The middle 50% is the range between the first and third quartiles. In this group of 9 numbers, the first quartile is the average of numbers 2 and 3 when the numbers are listed from smallest to largest.
first quartile = (230 +281)/2 = 255.5 . . . . . . matches answer choice B
The third quartile is the average of numbers 7 and 8:
third quartile = (468 +531)/2 = 499.5 . . . . . also matches answer choice B
The middle 50% is 255.5 to 499.5.
_____
When I put the numbers in order, I get ...
198 230 ^ 281 246 376 426 468 ^ 531 540
^ indicates that the quartile here is the average of the adjacent numbers
bold indicates the median (2nd quartile)
