Phil and his family want to do something fun and memorable on leap day. they each come up with an activity: attend a trapeze class, go fishing, go on a hike, or visit a theme park. they settle on picking the letters l, e, a, and p from a bowl, replacing them after each pick, to make the decision. they repeat this experiment 40 times to verify their model and record the results in this table.

activity

letter

times picked

trapeze class l
10

fishing e
11

hiking a
9

theme park p
10

based on the results in the table, is this model a fair representation for choosing an activity?

no, it is an unfair model because the outcomes have different frequencies.

no, it is an unfair model because the relative frequency of the letter e is the highest.

yes, it is a fair model because the relative frequencies of the letters l and p are equal.

yes, it is a fair model because the relative frequencies of all the outcomes are similar.

Hey.. ♥️♥️ me in solving this question

Apackage of supplies is dropped from a plane, and one second later a second package is dropped. neglecting air resistance, the relative velocity of the 1st package viewed from the second will 56) a) increase. b) be constant. c) be zero. d) depend upon their weight. e) decrease

Follow these directions and answer the questions. 1. set up the ripple tank as in previous investigations. 2. bend the rubber tube to form a "concave mirror" and place in the ripple tank. the water level must be below the top of the hose. 3. generate a few straight pulses with the dowel and observe the reflected waves. do the waves focus (come together) upon reflection? can you locate the place where the waves meet? 4. touch the water surface where the waves converged. what happens to the reflected wave? 5. move your finger twice that distance from the hose (2f = c of c, center of the curvature) and touch the water again. does the image (the reflected wave) appear in the same location (c of c)? you may have to experiment before you find the exact location. sometimes it is hard to visualize with the ripple tank because the waves move so quickly. likewise, it is impossible to "see" light waves because they have such small wavelengths and move at the speed of light. however, both are examples of transverse waves and behave in the same way when a parallel wave fronts hit a curved surface.
