Answer:
75% off
Step-by-step explanation:
I would personally say use a calculator, but whatever your instructor says.
First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.
Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.
So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
Answer:
The coefficient of correlation=0.5
Step-by-step explanation:
We are given that
Covariance between the variable x and y=18
Variance of x=16
Variance of y=81
We have to find the coefficient of correlation
We know that
Coefficient of correlation

Using the formula



Hence, the coefficient of correlation=0.5
Answer:
The answer is -1/2
Step-by-step explanation:
We first start by removing x in order isolate the y variable
2y = 6 - x
y = 
Further, we simplify the equation in order to get the value of m (slope)
y = 3 + 
Therefore, our slope is equivalent to -1/2
On Saturday - x tickets
on Friday - (x + 100)
altogether
x+x+100=3300
2x=3200
x=1600
x+100=1600+100=1700
