There would be a 0.71% decrease, rounded to the nearest tenth of a percent would be a 0.7% decrease. :)
The slope should be m= -9/11
For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
There are three elements in that set.
The probability of winning a game out of 20 is 4 times.
