State the domain and range for the following relation. Then determine whether the relation represents a function

Marysya12 [62]

Answer:

Domain: {XS, Red, Yellow, 45, A}

Range: {Size, Color, Number, Letter}

Step-by-step explanation:

The domain of the function shown in the mapping above are all variables that fall under "A word", while the range consists of all variables under "category".

The mapping shows that the relation represents a function, because each domain variable has exactly one range variable. No single domain variable is mapped to two different range variable.

The correct answer is:

Domain: {XS, Red, Yellow, 45, A}

Range: {Size, Color, Number, Letter}

15 and 17 pls.. 15 points!!!!

Maurinko [17]

Step-by-step explanation:

15) 50 ÷ 2 = 25

17) Mean = 301, Mode = 40-50

(10+20) ÷ 2 = 15, (20+30) ÷ 2 = 25, (30+40) ÷ 2 = 35

(40+50) ÷ 2 = 45, (50+60) ÷ 2 = 55, (60+70) ÷ 2 = 65

(70+80) ÷ 2 = 75

• 15×4 = 60, 25×8 = 200, 35×10 = 350, 45×12 = 540

55×10 = 550, 65×4 = 260, 75×2 = 150

Mean = (60+200+350+540+550+260+150) ÷ 7

= 2110 ÷ 7

= 301.4285....

= 301

Mode : the highest frequency
