Answer:
15
Step-by-step explanation:
= 
Cross multiply 120*100 = 800x
12000= 800x
15 = x
Answer: 6g^2+9g-6
Step-by-step explanation:(g+2)(6g−3)
=(g+2)(6g+−3)
=(g)(6g)+(g)(−3)+(2)(6g)+(2)(−3)
=6g^2−3g+12g−6
=6g^2+9g−6
Answer:
Jason Inherit a land with a 45% chance of having oil.
Step-by-step explanation:
The probability of the land having oil is = P
(
O)
=
45
/100
The probability of the land having oil is= Q(O
)
=55/100
The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.
The probability of the correct reading is= P(M)=80/100
The probability of the incorrect reading is=Q(M)=20/100
The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present × probability of the incorrect reading
Probability=P(O) x Q(M)
Probability=45/100 x 20/100
Probability=9/100
The probability of the test predicting no oil in land and the land has oil is 0.09 or 9%
