Question

maya collected data about the number of ice cubes and milliliters of juice in several glasses of juice and organized the data into this table. ice cubes 4 2 3 5 5 3 1 juice (milliliters) 177 234 202 140 155 210 265 she used a graphing tool to display the data in a scatter plot with x representing the number of ice cubes and y representing the milliliters of juice. then she used the graphing tool to find the equation of the line of best fit: y = - 29.202x + 293.5. based on the line of best fit, approximately how many milliliters of juice will be in a glass with 7 ice cubes? a. 10 b. 89 c. 110 d. 208

Explanation:

Step1: Identify the given equation

The equation of the line of best - fit is $y=-29.202x + 293.5$, where $x$ is the number of ice - cubes and $y$ is the milliliters of juice.

Step2: Substitute the value of $x$

We are asked to find the number of milliliters of juice when $x = 7$. Substitute $x = 7$ into the equation:
$y=-29.202\times7 + 293.5$.

Step3: Perform the multiplication

$-29.202\times7=-204.414$.

Step4: Perform the addition

$y=-204.414 + 293.5=89.086\approx89$.

Answer:

B. 89
