What information is provided in a typical stem-and-leaf plot?

When the levels of a variable can be ordered on some continuum or dimension from high to low, that variable is said to be measured on at least a(n) _____ level.

Write the standard form equation of the parabola with a focus at (4,-1) and a directrix at y=5.    You should show work for this problem. 

Based on the stem-and-leaf plot below, representing scores on an exam, what was the frequency for a score of 36? 10 : 0  9 : 2  8 : 233  7 : 5  6 :  5 : 00555588  4 : 222  3 : 666  2 : 777  1 : 7  0 : 8 *each stem represents the hundreds and tens place; each leaf represents the ones place

A researcher is interested in whether frequencies of ice cream preference are evenly distributed across the three categories of vanilla, chocolate, and strawberry. Use the data in the table below to test the prediction that ice cream preference is evenly distributed. **Report the observed chi-square statistic to 4 decimal places. Ice Cream Preference N Vanilla 87 Chocolate 64 Strawberry 44  

For  please give the following information:  Type of Conic Section — 0.5pt Standard Form of Equation — 2pts All coordinates and equations that are important for this conic section (this includes the orientation/direction of the graph, if applicable). — 3pts Graph (must include easy-to-read axes with tick marks, all important coordinates, and lines). — 2.5pts Your uploaded work should have your steps for writing the equation in standard form and your graph.
