Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )

Answer:
Answered below
Explanation:
# Program is written in Python programming language
conditioner_in_ml = 0
width = float(input("Enter width in inches: "))
height = float(input("Enter height in inches: "))
length = float (input("Enter length in inches: "))
#Calculate the volume
volume = width * length * height
#Calculate the amount of conditioner per 100 #cubic inches of volume
conditioner_in_ml = volume/ 100
print("The amount of conditioner required for $volume cubic inches is $conditioner_in_ml ml")
Answer:
5
Explanation:
The operator 'x++' is called the post increment operator, it is assign first and then increment.
The operator '++x' is called the pre increment operator, it is increment first and then increment.
So, both are increment operator which increment the value by one.
initially the value of x is zero,
++x increase the value to 1 and than assign to x.
then, x++ it assign to x first then increment by 1 means x=2
and so on.....
Their are five increment operator are used. so, the result is 5.
