Deci- means 1/10 or .1 of a unit.
Answer:
1/4y
Step-by-step explanation:
(-x^-1)^0/(4y^-1*y^2)
anything to the power of 0 gives you 1,
1/(4y^-1*y^2)
-1+2=1
1/4y^1=1/4y
Answer:
810
Step-by-step explanation:
In this case the sample space would be the number of combinations that can be made with the numbers from 1 to 30 with the letters of the alphabet, from "a" to "z", for example:
A1, A22, C4, F9, etc
Now we know how many numbers are 30, now the alphabet has 27 letters, therefore, the number of combinations are:
27 * 30 = 810
Which means that the total number of results is 810.
(22 + 15.50 + 2.75) 15
(22 * 15) + (15.50 * 15) + (2.75 * 15)
