Which selection from the list below provides the most complete and accurate description for the number of days mankind has walked the earth variable: A. It is a variable that is both Quantitative and Continuous
B. It is a variable that is Discrete
C. It is a variable that is Quantitative
D. It is a variable that is neither Quantitative nor Continuous
E. It is a variable that is both Quantitative and Discrete.

E.

Step-by-step explanation:

The variable that represents this would be both Quantitative and Discrete. This is because since this variable is measuring the amount of days it has a value type which therefore makes it a Quantative variable. Also, since the number of days that mankind has waled the Earth is a finite value, regardless of how large it may be, it would be considered to be a discrete variable. Continuous variables would be something along the lines of "What is the size of the Universe?" because the value of this variable would be neverending since we cannot calculate it.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
