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%

Answer:
53 bagels
Step-by-step explanation:
The number of bagels, y sold is a function of the square of the time (x) plus 4.
Therefore:
Number of Hours from 12.00 am to 7:00 am =7
At x=7
The number of bagels sold,
The bagel shop sold 53 bagels from 12: 00 am to 7: 00 am.
