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%
You can distribute the q to both terms to get

Hi there!
The question sounds really complex, but the mathematical operations behind it is figuratively simple. Here, we are told to find 19 (18.7 rounded up is 19) percent of 1,000. To do this, we can set up a proportion to model the whole scenario.

Now, just solve for x by cross multiplying and simplifying.



Therefore,
190 people out of 1,000 people leave out pertinent information on their IRS forms. Hope this helped and have a terrific day!
Hello from MrBillDoesMath!
Answer:
Number marbles >= 5
Discussion:
The only certain thing we can say is the jar contains at least 5 (green) marbles. The table shows probabilities, not certainties, and is no guarantee that any other marbles even exist in the jar,
Thank you,
MrB
Find out the statement true regarding the diagram given in the question
Answer
the statement is true regarding the diagram is
m∠WXY + m∠YXZ = 180°
REASON
As shown in the diagram
∠WXY and ∠ YXZ are supplementary angles.
Supplementary angle definition
Two Angles are said to be Supplementary when there sum is equal to 180 °.
thus we get
m∠WXY + m ∠YXZ = 180 °
Therefore the m∠WXY + m∠YXZ = 180° is the true statement.
