Operation: Addition ( + )
Key word/phrase: plus, more than, the sum of, the total of, increased by, and added to.
Example: A number plus three, Ten more than a number, The sum of a number and five, The total of six and some number, A number increased by two, Eleven added to a number.
Translation: x + 3, x + 4, x + 10, x + 5, x + 2, 6 + x, x + 11 and so on.
Subtraction ( − ) minus A number minus seven X – 7 less than Four less than a number X – 4 the difference of The difference of a number and three X – 3 less Nine less a number 9 – X decreased by A number decreased by twelve X – 12 subtracted from Six subtracted from a number
Multiplication ( x ) times Eight times a number 8x the product of The product of fourteen and a number 14x twice; double Twice a number; double a number 2x multiplied by A number multiplied by negative six −6x of Three fourths of a number
Division ( ÷ ) the quotient of The quotient of a number and seven divided by Ten divided by a number the ratio of The ratio of a number to fifteen
Powers ( x^n ) the square of; squared The square of a number; a number squared x^2 the cube of; cubed The cube of a number; a number cubed x^3
Equals ( = ) equals Seven less than a number equals ten. x − 7 = 10 is Three times a number is negative six. 3x = −6 is the same as Eight is the same as twice a number. 8 = 2x yields Twelve added to a number yields five. x + 12 = 5 amounts to Nine less a number amounts to twenty. 9 – x = 20

Answer:
d. Some customers had more than one drink.
Step-by-step explanation:
The exact question is as follows :
Given - Hannah wants to simulate whether customers will choose a small, medium, or large drink, or no drink at a fast food restaurant. She decides to use digits from a random number table to represent the drink option a customer will order (0=no drink, 1=small drink, 2=medium drink, 3=large drink, ignore digits 4-9)
To find - Why does this NOT model the situation?
a. The choices are not equally likely to occur.
b. Some of the digits were ignored.
c. The choice are independent of each other.
d. Some customers had more than one drink.
Solution -
The correct option is - d. Some customers had more than one drink.
Reason -
If Customer order more than one drink, then also he has to order either of the digits.
So, Hannah can not be sure about the order that he wants single order or wants to repeat the order.
