Answer:
0.9^10
Step-by-step explanation:
The probability to make an error in 1 question =0.1 => The probability that this one particular question will be answered correctly is P=1-0.1=0.9
There are 10 questions that are independent from each other .
The probability to be answered correctly is 0.9 each. So the probability to answer correctly to all of them is
P(10quest=correct) =0.9*0.9*0.9*0.9*0.9*0.9*0.9*0.9*0.9*0.9=0.9^10
Factor- 6(y+5)
Plz take full pick so discussing
Answer: 2x + 15 = 243
x = $114
Gas Tank: $15
Matthew: x
Devin: x
Gas Tank + Matthew + Devin = Total
15 + x + x = 243
2x = 228
x = 114
B=90
A=65
happy to help :)
