Answer:
y= -0.3x - 5.6
Step-by-step explanation:
m= (-5)-(-8)/(-2)-8
m= -0.3
y=mx+c
-8= -0.3(8)+c
-8= -2.4 +c
-8+2.4=c
c= -28/5
y= -0.3x - 5.6
The commutative property of multiplication states that the numbers can be multiplied in any order.
a+b = b+a : Commutative property of addition
a*b = b*a : Commutative property of multiplication
a+0=a : Additive identity property
a*1 =a : Multiplicative identity property
Answer : a*b =b*a
Move the decimal 2 places to the right resulting in the answer 2,380

Answer:
The expected number of appearance defects in a new car = 0.64
standard deviation = 0.93(approximately)
Step-by-step explanation:
Given -
7% had exactly three, 11% exactly two, and 21% only one defect in cars.
Let X be no of defects in a car
P(X=3) = .07 , P(X=2) = .11 , P(X=3) = .21
P(X=0 ) = 1 - .07 - .11 - .21 = 0.61
The expected number of appearance defects in a new car =
E(X) = 
= 
= 0.64
= variation of E(X) = 
= 
= 
= 0.8704
standard deviation = 
= 
= 0.93(approximately)
