Determine whether the following problem involves a permutation or combination.​ (It is not necessary to solve the​ problem.) How many different ​-letter passwords can be formed from the letters ​S, T​, U​, ​W, X​, Y​, and Z if no repetition of letters is​ allowed?

The problem involves (combination or permiation) because the (order or number) of letters selected (does or does not) matter.

Step-by-step explanation:

The order matters

stuwxyz is different than zyxwuts

You have 7 letters

The number of permutations is 7! which is 7*6*5*4*3*2*1 = 5040

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
