Answer:
x=136
Step-by-step explanation:
To find the measure of the sum of the interior angles use the formula (n-2) times 180 where n is the number of sides.
A quadrilateral has 4 sides. (4-2) times 180. 2 times 180=360
The sum of the interior angles of a quadrilateral is 360.
x+47+95+82=360
x+ 224 = 360
x= 136
It would be 2/10, or 1/5, since two out of the 10 numbers are even. 2/10 simplifies to 1/5, since there is 1 for every 5 numbers.
We could turn this into a percentage by dividing 1 by 5, which gives us 0.2. Then we can multiply by 100 to get 20.
So, our probability of choosing an even number is:
2/10
OR
1/5
OR
20%

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)
