50 girls attended the trip.
80 boy + 50 girls = 130 total students
8x10 =80
5x10=50
multiply both by 10.
12$ per 3×3 if its square yard
so 180 ÷ 9 = 20
20×12$=240$
<span>Yes, the two events are independent because P(NF|PB) = P(NF).
I'm not 100% sure though so wait til someone else answers :)</span>
Answer:
k≥-1.5
Step-by-step explanation:
-(5k-3) ≤ 15 + 3k
-5k+3 ≤15 +3k
+5k +5k
3≤15+8k
-15 -15
-12 ≤ 8k
divide both sides by 8
-1.5 ≤ k
or k≥-1.5
Hope this Helps!!!
