Answer:
1/4
Step-by-step explanation:
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
Replace
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
P(pink, replace, pink) = 1/2 * 1/2 = 1/4
Answer:

Answer:
(x,y)=(5,-1)
Step-by-step explanation:
1. 2x+y=9 ---> y=9-2x
2. Substitute y=9-2x into 3x-2y=17 ---> 3x-2(9-2x)=17 ---> 3x-18+4x=17 --> 7x=35 ---> x=5.
3. Substitute x=5 into 2x+y=9 ---> 2*5+y=9 ---> y=9-10 ---> y= -1
Answer:
c 39
Step-by-step explanation:
Parameter is the sum of the lengths of all sides of a polygon. The sides of the polygon are PT, TS, SR, RQ, and QP. To get the length of a side, we use the distance formula: Each vertex in the polygon has its corresponding points:\
So to get the length of side PT, we use the distance formula and the vertices of side PT:
The length of PT is
The same procedure is done for the other 4 sides and the following are the answers:
And by adding all the sides, you get the perimeter:
By rounding off, the answer is 39 units.
