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:
Step-by-step explanation:
Start with the distance squared.
The distance from the center to the point on the circle is found from
Formula
d^2 = r^2 = (x2 - x1)^2 + (y2 - y1)^2
Givens
x2 = 2
x1 = - 5
y2 = -8
y1 = - 8
Center= (-5,-8)
Solution
r^2 = (2 - - 5)^2 + (-8 - - 8)^2
r^2 = 49 + 0
r^2 = 49
equation
(x + 5)^2 + (y + 8)^ = 49
