Step-by-step explanation:
Of the 28 students, 5 are female. So the probability is 5/28.
Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So,
(8,10) is not included in the solution area for the system.
Answer:
see below
Step-by-step explanation:
f(x) = 2x + 9,
Let x = -1
f(-1) = 2(-1) +9
= -2 +9
= 7
Okay well the way I do it is like this. When ever the next hour hits 10 minutes that is one hour then add the minutes left. So from 7:10a.m. to 6:10p.m. is 11 hours. Now the rest of the minutes. 6:35 -6:10=:25. So she has been away from the house for 11 hours and 25 minutes
