Answer:
1/3 is closest to zero.
Step-by-step explanation:
1/3 is closest to zero.
Seven more than 3 times a number is equal to 49 can be put into an equation form, which would be 7 + 3x = 49. With this equation we can work it out, first we will subtract 7 from both sides of the equation to cancel out the 7. 49 - 7 = 42. Now we have 3x = 42. To isolate x and give us the answer we will divide by 3 on both sides, since 3 is being multiplied by x. This will give us our answer, which is 14.
Answer:
solution is (3, - 1)
Step-by-step explanation:
given the 2 equations
x + y = 2 → (1)
x - y = 4 → (2)
Adding the 2 equations term by term will eliminate the y-term
(x + x) + (y - y) = (2 + 4)
2x = 6 ( divide both sides by 2 )
x = 3
substitute x = 3 in either (1) or (2) for y
(1) → 3 + y = 2 ( subtract 3 from both sides )
y = 2 - 3 = - 1
solution is (3, - 1)
Answer:
0.01864
Step-by-step explanation:
Let A be the event that a person was authorized and NA be the event that the person was not authorized. Let R be the event that a person was refused admission and G be the event that a person was granted admission.
Then we have to find P(A|R) = [P(A)*P(R|A)]/P(R)
putting value we get
P(R) = P(A)P(R|A) + P(NA)P(R|NA) = 0.95*(1/1000) + 0.05*((1,000,000-1)/1,000,000) = 0.0.05094995
P(A|R) = [P(A)*P(R|A)]/P(R)
= [0.95*(1/1000)]/(0.05094995)
=0.01864
