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)
<h2>
Answer:</h2>
<u>The area is</u><u> 168 yd²</u>
<h2>
Step-by-step explanation:</h2>
The area of Trapezoid is given by
A= (a+b)/2 * h
Putting the values
A = (5+23)/2 * 12
A = 168 yd²
Answer:
0.19
0.13
0.11
because that is how 19, 13, and 11 percent are represented in decimal form

Answer:
The value of the constant of proportionality r is 1
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Find the value of the constant of proportionality r
For x=5.8, y=5.8
substitute
The linear equation is
therefore
The value of the constant of proportionality r is 1
