Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. the amount of snowfall in december in city a b. the number of bald eagles in a country c. the gender of college students d. the number of statistics students now reading a book e. the number of people with blood type a in a random sample of 18 people f. the number of points scored during a basketball game

a) a continuous random variable; b) a discrete random variable; c) not a random variable; d) a discrete random variable; e) a discrete random variable; f) a discrete random variable

Step-by-step explanation:

A continuous random variable is one that can take multiple values between whole number values; for instance, fractions and decimals.  Snowfall is a continuous random variable.

A discrete random variable is one that can only take whole number values.  The number of bald eagles, the number of students reading a book, the number of people with blood type A, and the number of points scored in a  basketball game are discrete random variables.

Gender of students is not a numerical value; this is not a random variable.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
