You want to get the x's on one side and all the other numbers on the other side of the equation.
2x-5x+6=0
2x-5x=-6
-3x=-6
x=2
Answer:
0.5578
Step-by-step explanation:
Fingerprint correctly match 92 % of the time.
A novice that will correctly identify a match 75% the time.
Each of the attempts of matching a fingerprint with the individual is independent.
The number of pairs are 7.
a). So the probability that the expert will identify every pair correctly is
= 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92= 0.927 = 0.5578
Step-by-step explanation:
c
if you divide the answer althrough by 2 you should get the above equation
Replace x in the equation with 3.5 and do the arithmetic.
y = 1.3*3.5 -0.52
y = 4.55 -0.52
y = 4.03
The predicted approximate value of y is 4.03.
