Answer:
y = 2x + b
I dont know what b is but the slope is 2 I think
(1) From the information given, if we want to choose 5 colors from 8 distinct colors and the order in which the selection is made is relevant, then what we have is a permutation.
The formula is given as;

This formula means we need to select/arrange r items out of a total of n items and the anwer derived would be the total number of arrangements possible.
Therefore, we would have;

Therefore, if the order is relevant, this selection can be done in 6,720 ways.
(2) If the order is NOT relevant, then what we need to calculate is a combination and the formula is;

The formula can now be applied as follows;

If the order is not relevant, then the selection can be done in 56 ways.
Answer:
D.
Step-by-step explanation:
I don't know much about this but as far as I can tell the mean is about 8, that would make the deviation value of about 2
So for Tom to get his free meal he needs to spend 50 dollars.
This means the following⬇️

This equation is the 50 dollars he has to spend minus the 30.25 he has already spent which results in⬇️

This results in Tom needing to still spend 19.75 more dollars to get his free meal!!
Hope this helped!!
