Tommy has the following data: 16, 18, 15, u If the mode is 18, which number could u be? Choices: (A)15 (B)18

Identify Data and Question: Step 1: Identify the given data and the question prompt. Tommy has the numbers 16, 18, 15, and an unknown number u. We need to find the value of u such that 18 is the mode of the dataset. Definition of Mode: Step 2: Understand the definition of mode. The mode is the number that appears most frequently in a dataset. Since 18 is given as the mode, it must appear more frequently than any other number in the list. Analyze Choices for u: Step 3: Analyze the choices for u. Choices for u are 15 and 18. If u is 15, then the numbers are 16, 18, 15, 15. If u is 18, then the numbers are 16, 18, 15, 18. Determine Mode Choice: Step 4: Determine which choice for u makes 18 the mode. If u = 15, then 15 and 18 both appear twice, so there is no single mode. If u = 18, then 18 appears three times, making it the mode.

Identify Data and Question: Step $1$ : Identify the given data and the question prompt. $\newline$ Tommy has the numbers $16$ , $18$ , $15$ , and an unknown number $u$ . We need to find the value of $u$ such that $18$ is the mode of the dataset.
Definition of Mode: Step $2$ : Understand the definition of mode. $\newline$ The mode is the number that appears most frequently in a dataset. Since $18$ is given as the mode, it must appear more frequently than any other number in the list.
Analyze Choices for $u$ : Step $3$ : Analyze the choices for $u$ . Choices for $u$ are $15$ and $18$ . If $u$ is $15$ , then the numbers are $16$ , $18$ , $15$ , $15$ . If $u$ is $18$ , then the numbers are $16$ , $18$ , $15$ , $18$ .
Determine Mode Choice: Step $4$ : Determine which choice for $u$ makes $18$ the mode. $\newline$ If $u = 15$ , then $15$ and $18$ both appear twice, so there is no single mode. If $u = 18$ , then $18$ appears three times, making it the mode.
