Adanya makes and sells knit scarves. Next week she will pay a $25.25 fee for the use of a booth at a craft fair. She will charge $12.75 for each scarf she sells at the fair. Write an expression to determine Adanya's profit for selling s scarves after paying the fee for the use of the booth.

Assume that Friday morning taxi-cab rides have times with a standard deviation of =9.8 minutes. A cab driver records times of rides during a Friday afternoon time period and obtains these statistics n = 12, = 21.5 minutes, s = 13.3 minutes. Use a 0.01 significance level to test the claim that these Friday afternoon times have greater variation than the Friday morning times. Assume that the sample is a simple random sample selected from a normally distributed population.

Let denote the population standard deviation of Friday afternoon cab-ride times. Identify the null and alternative hypothesis:

: ____

: ____

Place the steps in the correct order for solving the system of linear equations.

• Combine like terms. (the x's)
• Substitute the value of x linto either equation to solve for y.
• Substitute the value of y from the equation written into the other equation.
• Simplify by distributing.
• Rewrite the equation 3x + y = 9 in slope-intercept form. (y=mx+b)
• Solve for x
