We write f(x) in terms of y I.e y=7x-1/2.
Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.
Make x the subject, x=2y+1/14,
Thus the inverse f(x)=2x+1/14
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:
0.4
Step-by-step explanation:
Given that:
P(debt) = P(D) = Probability of being in debt = 0.7
P(debt n Midwest) = P(Dn M) = probability of being in debt and lives in Midwest = 0.280
The probability that a randomly selected farmer lives in the Midwest given that he is in debt is?
P(M | D) = p(D n M) / p(D)
P(M | D) = 0.280 / 0.7
P(M | D) = 0.4
Answer: The greatest common factor of 4 and 6 is 2
Step-by-step explanation:
0.45 Isn't Equal To Any Of These Fractions But It Is Equal To 45/100
