A container contains tiles numbered from 1 through 40. A tile is drawn randomly and replaced. Then a second tile is drawn random
1 answer:
Answer:
The correct answer is .
Step-by-step explanation:
A container contains tiles numbered from 1 through 40.
Let the experiment be to drawn a tile randomly from the container. The draws are carried on by replacement method. Then a second tile is drawn randomly.
Probability that the first tile is number 7 = =
Probability that the second tile is number 25= =
Thus the probability of the first tile is number 7 and the second tile is number 25 is given by .

Answer:
x ≤ -20 or 5 ≤ x
see attached for a graph
Step-by-step explanation:
You have done most of the work of solving the inequalities. The steps are ...
- add the opposite of the constant on the side with the variable
- multiply by the inverse of the coefficient of the variable.
x/5 -x ≤ -6
x/5 ≤ -4 . . . . . add 2
x ≤ -20 . . . . . multiply by 5
__
8x +1 ≥ 41
8x ≥ 40 . . . . . add -1
x ≥ 5 . . . . . . . multiply by 1/8
So, the two inequalities you want to graph are ...
x ≤ -20 or 5 ≤ x
The values x = -20 and x = 5 are part of the solution set, so there would be solid dots at those points. The shading of the number line will extend outward from those points.
