The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed. However, it all depends on what you are trying to show from your data.
I can't directly tell you the answer, but I can help you for how to do it.
So every single time you want to find the rate of change (slope) label 2 points with x1, y1, x2 and y2. We can use the point-slope form to sind the slope:
y1-y2/x1-x2
And we just need to plug in the point to get the Y intercept.
When the x is 0, the y value will be the y-intercept.
The slope intercept form is: y=Mx+B. M stands for slope and B stand for y-intercept. Just plug the slope and y-intercept in and get the answer.
This makes sense to me: m=(y-6)/3
m is the number of muffins each friend gets, y is the original quantity of muffins, -6 is = to the number of muffins you freeze, and the /3 is to split the remaining (unfrozen) muffins equally.
Company A charges a $125 annual fee plus $7 per hour car share fee.
Company B charges $110 plus $10 per hour. The minimum number of hours that a car share needs to be used per year to make company A a better deal is 6 hours.
A: y=125+7 x
B: y=110+10 x
for A to be a better deal than B, 125+7 x<110+10 x has to be true
subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3 x
divide by 3: 5<x
so x has to be greater than 5 , im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you.
Equations are not always balanced on both sides using a "equal to" symbol in mathematics. Sometimes it can be about a "not equal to" relationship, meaning that something is superior to or inferior to another. In mathematics, an inequality is a relationship between two numbers or other mathematical expressions that results in an unequal comparison. Inequalities are the name given to certain algebraic mathematical expressions.
