Answer: p value is 0.1685.
Step-by-step explanation:
Since we have given that
The survey is conducted on a random sample of 240 pet owners.
Out of them, number of owners spoke to their pet on telephone = 79
n = 240
x = 79

Our hypothesis would be

Formula for test statistic would be

p value = 0.1685
Hence, p value is 0.1685.
This means that...
the first worker does 1/8 of the job each hour.
the second worker does 1/4 of the job each hour.
the third worker does 1/4 of the job each hour.
So together they get 1/8+1/4+1/4 of the job done per hour.
Rate: 5/8 of the job per hour
Now if we know the rate, the job will be finished in...
1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes
answer: 1.6 hours or 1 hour and 36 minutes

Answer:
-4, 0
Step-by-step explanation:
The denominator is x^2+4x. This is zero when ...
x^2 +4x = 0
x(x +4) = 0
The zero product rule tells you the product is zero when the factors are zero.
x = 0
x +4 = 0 ⇒ x = -4
The denominator is zero for x=0 and x=-4.
