Answer:
-6
Step-by-step explanation:
= -3 × -3
-3 × -3 = 9
7 × -3 =-21
9 - 21 +6 = -6
The probabillity can be found by using binomial probability formular considering that the event is discrete in nature and there are two possiple outcomes.
Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
