The following are the lengths of stay in days) for a random sample of 23 patients discharged from a particular hospital: 13,9,5, 11, 6, 3, 12, 10, 11, 7, 3,9, 5, 12, 9, 8, 8, 4, 4, 4, 11, 11, 11
Draw the histogram for these data using an initial class boundary of 2.5, an ending class boundary of 14.5, and 6 classes of
equal width. Note that you can add or remove classes from the figure. Label each class with its endpoints.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

Which point-slope form equation represents a line that passes through (3,-2) with a slope of -4/5
