Answer: 0.25
Step-by-step explanation:
The relative frequency of the customers that buy computers is equal to the number of customers that bought a computer divided the total number of customers that entered the shop.
p = 25/100 = 0.25
If we take this as the probability, then the probability that the next customer that enters the shop buys a computer is 0.25 or 25%
16 quarters and 10 nickels.
16 quarters are worth 4.00 and 10 Nickels are worth .30
<span>specific heat (
![C_p ](https://tex.z-dn.net/?f=C_p%20%0A)
) - the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree)
the equation related to this theory is
</span><span>
![Q=mC_p \Delta T](https://tex.z-dn.net/?f=Q%3DmC_p%20%5CDelta%20T)
Where Q is the energy gained or lost from the system
m is the mass of the object
</span><span>
![C_p](https://tex.z-dn.net/?f=C_p)
is the specific heat of the material
![\Delta T](https://tex.z-dn.net/?f=%5CDelta%20T)
is the change in temperature
