The coefficient of the expression is 0.25, and it represents the late fee for every day the book was overdue
Answer:
![\displaystyle 4x - y = 21, -4x + y = -21, or\:y = 4x - 21](https://tex.z-dn.net/?f=%5Cdisplaystyle%204x%20-%20y%20%3D%2021%2C%20-4x%20%2B%20y%20%3D%20-21%2C%20or%5C%3Ay%20%3D%204x%20-%2021)
Step-by-step explanation:
In this case, the <em>y-intercept</em><em> </em>and <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] are given to us, so just put it in Slope-Intercept Form:
![\displaystyle y = 4x - 21](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20%3D%204x%20-%2021)
If you want it in <em>Standard Form</em>:
y = 4x - 21
- 4x - 4x
_________
![\displaystyle -4x + y = -21\:OR\:4x - y = 21](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-4x%20%2B%20y%20%3D%20-21%5C%3AOR%5C%3A4x%20-%20y%20%3D%2021)

Answer:
the probability of choosing more than 3 non defective units out of a sample of 4 is 0.784 ( or 78.4%)
Step-by-step explanation:
Assuming that all the microwaves come from shipments selected at random, such that the probability of each microwave to be defective is independent from the others, then the random variable X= number of microwave units that are defective , has a binomial distribution such that the probability distribution is
P(X) = n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)
where
n= number of microwaves bought=4
x= number of microwaves that are defective
p= probability that a microwave has defective units = 2/9
then the probability that the restaurant buys at least 3 nondefective units is
Pfinal = P(X≤1)=P(X=1)+P(X=0) = 0.418 + 0.366 = 0.784
5(-3-2(5)) which equals to -15 -10 = -25
So, it will take 1 liter of milk to make 1/3 jug of tea.
