Please help I don't understand 1. Find the distance to the image in the following curved mirror problems and state whether the image is virtual or real AND whether it is upright or inverted. (4 points each)
a. An object is placed 1.0 cm from a convex mirror with a focal length of 4.0 cm.
b. An object is placed 12 cm from a convex mirror with a focal length of 5.0 cm.
c. An object is placed 110 mm from a concave mirror with a focal length of 5.0 cm.
d. An object is placed 9.0 cm from a concave mirror with a focal length of 9.0 cm.
e. An object is placed 1.5 cm from a concave mirror with a focal length of 3.0 cm.

Use the frequency histogram to complete the following parts. ​(a) identify the class with the​ greatest, and the class with the​ least, relative frequency. ​(b) estimate the greatest and least relative frequencies. ​(c) describe any patterns with the data. female fibula lengths 30.5 31.5 32.5 33.5 34.5 35.5 36.5 37.5 38.5 39.5 0 0.05 0.1 0.15 0.2 0.25 length (in centimeters) relative frequency a histogram titled "female fibula lengths" has a horizontal axis labeled "length in centimeters" from 30.5 to 39.5 in increments of 1 and a vertical axis labeled "relative frequency" from 0 to 0.25 in increments of 0.05. the histogram contains vertical bars of width 1, where one vertical bar is centered over each of the horizontal axis tick marks. the approximate heights of the vertical bars are listed as follows, where the label is listed first and the approximate height is listed second: 30.5, 0.02; 31.5, 0.04; 32.5, 0.05; 33.5, 0.13; 34.5, 0.22; 35.5, 0.25; 36.5, 0.13; 37.5, 0.06; 38.5, 0.09; 39.5, 0.01. ​(a) the class with the greatest relative frequency is nothing to nothing centimeters. ​(type integers or decimals. do not round. use ascending​ order.)
