1. yaritza has test scores in her cooking class of 85,92,99,100, and 95. what will her next score have to be if she wants to have a test average of 94 after all 6 tests?

Explanation:

Step1: Calculate the total sum of the first 5 scores

The sum of the first 5 scores is \(85 + 92+99 + 100+95=471\).

Step2: Calculate the total sum of 6 scores for an average of 94

Since the formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), and \(n = 6\), \(\bar{x}=94\), then the total sum of 6 scores is \(94\times6 = 564\).

Step3: Find the sixth score

Let the sixth score be \(x\). We know that \(471+x=564\). Solving for \(x\), we get \(x=564 - 471\).

Answer:

\(93\)
