Answer: A) The sum of x and y is a rational number.

Step-by-step explanation:

A rational number is a number that can be expressed as a fraction , that is , it can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number

since x = -9 and y = -6

x + y = -9 + -6

x + y = -15

-15 can be written as -15/1 , this shows that it is a rational number.

Note : Irrational numbers can not be expressed as fraction ,example is \sqrt{2} , \pi and so on

Also , Imaginary number is a complex number

. A recent report in a women magazine stated that the average age for women to marry in the United States is now 25 years of age
Setler [38]

Answer: 0.0136

Step-by-step explanation:

Given : Mean : \mu=25

Standard deviation : \sigma=3.2

Sample size : n=50

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x = 24

z=\dfrac{24-25}{\dfrac{3.2}{\sqrt{50}}}=-2.21

The p-value = P(z\leq-2.21)= 0.0135526\approx0.0136

Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136
