PROBLEM 2: DeMario has two dimes and four quarters. Pratima has five dimes and two quarters. They have $2.20 altogether. Write an expression or equation that matches this situation.*

Find the volume of the solid obtained by rotating the region enclosed by the curves y=1x and y=7^-x about the x-axis. (use symbolic notation and fractions where needed.) volume =

What is the value of x? enter your answer in the box.

Which statements are true about box plots? check all that apply. they describe sets of data. they include the mean. they show the data split into four parts. they show outliers through really short “whiskers.” each section of a box plot represents 25% of the data.
