Answer:
23/40 is a rational number
Step-by-step explanation:
an irrational number cannot be written as a fraction - with a finite end. An irrational number would be a repeating decimal
The rate of change of the linear equation is 
Explanation:
The given two coordinates are
and 
To determine the rate of change, let us use the formula,

Substituting the coordinates in the equation, we get,

Simplifying, we have,

Dividing, we get,

Thus, the rate of change of the linear equation is 
Answer:
Defining the straight number of integers, we have to live in the year 2020 and this Greek historian was born in the year - 484.
Step-by-step explanation:
When using whole numbers, we denote positive numbers as the number of numbers after 0, and negative numbers the number of numbers before zero.
So if we consider the birth of Christ to be the year 0, then all years before Christ will be negative and all years after Christ will be positive.
So we have to live in the year 2020 and this Greek historian was born in the year - 484.

Complete question :
Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.
Millitary status _________ female ____ Male
In armed forces _________ 28 _______ 59
Millitary dependent ______ 928 ______ 781
Civilian _______________ 26393 ___27330
Answer:
Male = 0.4193
Female = 0.5087
Step-by-step explanation:
To obtain the marginal distribution of gender :
Total number of civilians (male + female)
(26393 + 27330) = 53,723
Male :
P(male) = number of male / total
P(male) = 26393 / 53,723 = 0.4912793
P(Female) = number of Female / total
P(Female) = 27330 / 53,723 = 0.5087206
