Okay. So, your bill is $75. But since you spent over $50, you get a 20% discount. You get a 20% discount, but you still have to pay 80% of the price. To find the bill after the savings, multiply 75 by 80% (0.8). 75 * 0.8 is 60. Your final bill after the savings is $60.
Answer:
8
Step-by-step explanation:
Given,
f(x) = 8(x)
To value of a function at any point can be calculated by substituting that value in place of x.
Therefore,
f(1) = 8(1) = 8
f(2) = 8(2) = 16
The change over the interval from x=1 to x=2 can be calculated using
=>
=> 8
Divide the two lengths:
(X'Z')/(XZ) = 5/4 = 1.25
The final answer is choice D) 1.25
This means that the larger figure is 25% bigger in size (comparing corresponding segments).
Please review the concepts of mean, mode and median. The median is the single value that shows up most often in the list of data. Here I see that '10' shows up 5 times, more than 9 (4 times). The mode would thus be the best measure of central tendency here.
I challenge you to find the mean and median of this data set and then to complare both with the mode (10).
The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.
