a. No; the domain values are at regular intervals and the range values have a common factor 0.25.
b. No; the domain values are not at regular intervals although the range values have a common
factor.
C. Yes; the domain values are at regular intervals and the range values have a common factor 4.
d. Yes; the domain values are at regular intervals and the range values have a common factor

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
