H= 3 V/ Ab =3 x 168/36 = 14 cm
Let x be a random variable representing the mean saraly of professors at two year institutions, then
P(x > 55000) = 1 - P(z < (55000 - 52500)/4000) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.26599
Answer:
The answer is: The sum of x and y is a rational number.
Step-by-step explanation:
x is a rational number (any).
is a rational number too.
So, the sum of x and y will also be a rational number.
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
n = 240
mean = 22.3 hours
standard deviation = 6 hours
At 99% level of confidence, z = 2.58
So, interval would be

Hence, Option 'c' is correct.
The answer to 392,196=4,508
