Answer:
The probability that Jones is lying is 6/7
Step-by-step explanation:
First we will list out 2 different cases when the outcome is a lie
1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8
So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48
2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie
So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08
Total probability of outcome being a lie is 0.48+0.08=0.56
But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7
X/4+7=y
x being your "number" and y being the answer
Complete question :
Select the two statements that are true about the equation y−10=60(x−40)
Answer:
m = 60
One point on the line is (40, 10)
Step-by-step explanation:
Given the equation :
y−10=60(x−40)
Comparing the equation with the point slope equation formula :
y - y1 = m(x - x1)
Where, x1 and y1 are points on the line
m = Slope
From here, we can deduce that:
y1 = 10 ; x1 = 40 and m = 60
(x1, y1) = (40, 10)
m = slope = 40
Answer:
Coordinates of point A are
(-3,-2)
Origin lies in the center of coordinate system. That means that you can picture this as right triangle with sides 3 and 2 and you need to find hypotenuse of it.
Using pythagoras theorem we calculate:
h^2 = 3^2 + 2^2 = 13
h = sqrt 13
