Answer:
3/7 / 42.8% chance
Step-by-step explanation:
There are 6 striped balls (9, 10, 11, 12, 13, 14) and 8 (1, 2, 3, 4, 5, 6, 7, 8) solid colored balls. So, 6 / 14 balls are striped.
(6 / 14 = 3 / 7)
this means that the probability of a ball being striped has the odds of 3/7
(3/7 = about 42.8% chance)
Answer:
x = 31.4
PQ = 58.8
Step-by-step explanation:
Set up a proportion:
SQ/QP = ST/PR
Substitute in the values they give you:
This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8
The last one is the correct answer.
Answer:
I believe y = 90°
Step-by-step explanation:
70 + 110 = 180, so you know that both sides are the same angle. The angle of the two straight lines must be 90°
