van cise - omeokwu lab - basic lab skills assessment (this counts as a labs/projects grade) name: name redacted class: class redacted date: date redacted part 1. basic skills record the correct reading for each measurement. graduated cylinders are in milliliters and lengths are in centimeters. 1. measurement 1 2. measurement 2 3) a rectangular prism is filled to a depth of 0.85 cm. it has a length of 7.50 cm and a width of 14.5 cm. what is its volume? (show your algebra not your arithmetic.) 0.85 cm 7.50 part 2 spreadsheet skills 4) when using a spreadsheet to find a fit line, which variable must be inputted in the left - column? a. the independent variable b. the dependent variable c. it doesnt matter because the computer can tell which is which d. it doesnt matter because it doesnt matter which variable is graphed on which axis. 5) what type of graph must be used when using a spreadsheet to find the line of best fit? a. scatter plot b. line graph c. bar chart d. pie chart part 3 primary learning target 6) how is the slope of a line calculated? 7) what are the units of slope? (hint: look at the axes of the example graph.) 8) what do you think the
eal\ value of the slope \should have been?\ 9. what is the meaning of the slope? what does the slope of the line tell you about the
eal\ relationship between volume of water in ml and cm³? (you may write on the back if you need to.)

Explanation:

Step1: Recall volume formula

The volume formula for a rectangular - prism is $V = l\times w\times h$, where $l$ is length, $w$ is width and $h$ is height (or depth).

Step2: Identify given values

Given $h = 0.85$ cm, $l = 7.50$ cm and $w = 14$ cm.

Step3: Substitute values into formula

$V=(7.50)\times(14)\times(0.85)$

In a spreadsheet for finding a fit line, the independent variable is typically input in the left - hand column. This is because the independent variable is the one that is manipulated or controlled in an experiment or data set, and it is the basis for which the dependent variable is measured.

A scatter plot is used to find the line of best fit. It shows the individual data points, and from this, the trend line (line of best fit) can be determined. Line graphs are for showing trends over time or continuous data in a sequential order, bar charts are for comparing discrete categories, and pie charts are for showing proportions of a whole.

The slope of a line is calculated as the change in the y - variable divided by the change in the x - variable, also known as $\frac{\Delta y}{\Delta x}=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.

Answer:

a. The independent variable
