Jason Inherit a land with a 45% chance of having oil.
The probability of the land having oil is = P
The probability of the land having oil is= Q(O
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
The probability of the test predicting no oil in land and the land has oil is 0.09 or 9%
Start with the distance squared.
The distance from the center to the point on the circle is found from
d^2 = r^2 = (x2 - x1)^2 + (y2 - y1)^2
x2 = 2
x1 = - 5
y2 = -8
y1 = - 8
r^2 = (2 - - 5)^2 + (-8 - - 8)^2
r^2 = 49 + 0
r^2 = 49
(x + 5)^2 + (y + 8)^ = 49
1/4 is your answer
40 black ink cartridges and 19 colored ink cartridges
Let represent the number of black printer ink cartridges sold. Let represent the number of color printer ink cartridges sold.
Set up a system of equations:
⇒ 40 black ink cartridges, 19 colored ink cartridges (ans)
the difference in monthly pymts $59. 49/mthly
$59.49 × 12 = $713.88 increase in pymts in 1 year.
