Answer:
10.3
Step-by-step explanation:
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(7,-2)....x1 = 7 and y1 = -2
(-2,3)...x2 = -2 and y2 = 3
now we sub
d = sqrt ((-2 - 7)^2 + (3 - (-2)^2)
d = sqrt ((-9^2) + (5^2))
d = sqrt (81 + 25)
d = sqrt (106)
d = 10.295 rounds to 10.3 <===

Answer:
7/80
Step-by-step explanation:
(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P ( green or yellow ) = number of green or yellow / total
= (3+4)/20 = 7/20
Replace
so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P (blue) = number of blue/ total
= 5/20 = 1/4
P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80
