Answer:

speed = distance/time

Step-by-step explanation:

The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.

The two-way frequency table below shows data on behavior of students and the use of positive phone calls home as an incentive fo
Gemiola [76]

Answer:

Step-by-step explanation:

Hello!

In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.

In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.

If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n

For the students that received the phone call:

n= 19 + 9= 28

The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68

The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32

For the students that didn't receive the phone call:

n= 8 + 6= 14

The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57

The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43

I hope this helps!
