Answer:
number of ways = 120
Step-by-step explanation:
The number of ways five children can pose for a photograph line up in a row is given by the number of permutations of 5 elements in 5 different positions (positions in the line), then
number of ways = number of permutations of 5 elements = 5! = 5 * 4 * 3 * 2 * 1 = 120
Since the first children that occupies the line can be on any of the positions (5 positions) , but then the second one can choose any of the 4 remaining positions (since the first children had already occupied one) , the third can choose 3 ... and so on.
Answer:
Both graphs can be used.
Step-by-step explanation:
because the time and the difficultly of the grade both depend on how long they take. Therefore it would be both graphs can be used.
Answer:
C. m/1=m/2=54
Step-by-step explanation:
these two angles are equal hence:
5x-16=4x-2=-16+2 =-14
4x-5x=-x
-x=-14=x=14
then you substitute the value of 'x' with 14
therefore:(5×14-16)=54
(4×14-2)=54
m/1=m/2=54
