First step is find profit so lets subtract 93 and 15.
93-15=78
Finally we can divide profit by 3 students, so
78:3=26$ its the answer
Answer:
3/8
Step-by-step explanation:
First,
convert 3/4 of an hour to minutes;
If 1 hr = 60 mins
then 3/4 of 1hr = ![\frac{3}{4} *60\\ \\ =45 mins.Next, If 1/2 of 3/4 was spent practicing recital piece, it means that it is half of 45 mins;1/2 *45 = 22.5 minsLastly, convert the 22.5 mins into a fraction of an hour;22.5/60 = [tex]\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2A60%5C%5C%20%5C%5C%20%3D45%20mins.%3C%2Fp%3E%3Cp%3ENext%2C%20%3C%2Fp%3E%3Cp%3EIf%201%2F2%20of%203%2F4%20was%20spent%20practicing%20recital%20piece%2C%20it%20means%20that%20it%20is%20half%20of%2045%20mins%3B%3C%2Fp%3E%3Cp%3E1%2F2%20%2A45%20%3D%2022.5%20mins%3C%2Fp%3E%3Cp%3ELastly%2C%20convert%20the%2022.5%20mins%20into%20a%20fraction%20of%20an%20hour%3B%3C%2Fp%3E%3Cp%3E22.5%2F60%20%3D%20%5Btex%5D%5Cfrac%7B3%7D%7B8%7D)
**4/5** is equal to .8, so 4/5 is the answer. to check, multiply .8 x 5 = 4
The y-intercept of the linear equation of best fit, considering the slope and the means, is of -60.428.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For a line of best-fit, the y-intercept is given by:

The parameters in this problem are given as follows:
