It’s 20 cause if you look at the problem it’s 20
Seven hundred ten thousand two hundred
Im not sure if you need the work, but the answer is 3.8 hours. you make them into fractions, like in one hour ann could build 1/5 of the model car and sam 1/15 of the car. you use that to then find 1/x (how much they could build together) and multiply by the lcd. Its complicated sorry i cant explain well lol
The mean is: 7.6
The range is: 7
The median is: 7
The mode is: 5

<h3>Procedure - Determination of an appropriate function based on given information</h3>
In this question we must find an appropriate model for a <em>periodic</em> function based on the information from statement. <em>Sinusoidal</em> functions are the most typical functions which intersects a midline () and has both a maximum () and a minimum ().
Sinusoidal functions have in most cases the following form:
(1)
Where:
- - Angular frequency
- - Angular phase, in radians.
If we know that , , , and , then the sinusoidal function is:
(2)
(3)
The resulting system is:
(2b)
(3b)
By applying <em>inverse trigonometric </em>functions we have that:
, (2c)
, (3c)
And we proceed to solve this system:
,
By (2c):
The equation that represents the <em>sinusoidal</em> function is , .
