We know that
<span>A number x, rounded to 1 decimal place is 12.3
</span><span>so
x>=12.25
and
x < 12.35
</span><span>the error interval for x is the interval [12.25,12.35)
</span>
the answer is
[12.25,12.35)
Answer:
A) P(E|F) = 0.900
B) P(F|E) = 0.771
Step-by-step explanation:
P(E) = 0.7
P(F) = 0.6
P(E n F) = 0.54
A) P(E|F), the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked is given mathematically as
P(E|F) = P(E n F)/P(F) = 0.54/0.6 = 0.900
B) P(F|E), the probability that the second airline's flight is fully booked given that the first airline's flight is fully booked is given mathematically as
P(F|E) = P(E n F)/P(E) = 0.54/0.7 = 0.771
F(2) = -5(2) + 7
f(2) = -10 + 7
f(2) = -3
Answer:
(- 3, 5 )
Step-by-step explanation:
Given the 2 equations
x + y = 2 → (1)
5x + y = - 10 → (2)
Subtracting (1) from (2) term by term will eliminate the term in y, that is
(5x - x) + (y - y) = (- 10 - 2)
4x = - 12 ( divide both sides by 4 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (1)
- 3 + y = 2 ( add 3 to both sides )
y = 5
Solution is (- 3, 5 )
