Answer:
There are many examples the basics are also easy to remember.
Step-by-step explanation:
We can input these for the following equation.
x > 5
(x is greater than 5)
Then compare to - x < 5
(minus x is less than 5)
We try a sum
3x -2 ≤ 1
we can then balance subtract -2
3x ≤ -1
then divide by 3
x= -1 /3
We try another value
3x -2 ≤ 0
1 ≤ 3x
1/3 ≥ x
We can check that each equality fits and alter the number accordingly.
For the first one we are saying it is no greater than 1
For the second we say it is greater than zero.
We are able to prove both have the answer.
Just like when we look for negative percentages and count down we record this as we count in mental math.
Answer:
1. The probability that the T-shirt will be grey :-
=》

=》

=》

hence, the probability of grey t-shirt is 0.1
2. The probability that the T-shirt will not be red :-
=》

=》

=》

=》

The probability that the T-shirt will not be red is
0.8
3. He takes one of his blue T-shirts at random.
What is the probability that the T-shirt is light blue
total blue t-shirts = 5
so, the probability of choosing light blue t-shirt is
=》

=》

=》

hence, the probability of choosing light blue t-shirt is 0.2
Answer:
Choice A. (10, -1)
Choice B. (-8, 9)
Choice D. (6, -3)
Step-by-step explanation:
If we plug the coordinates of point A into the inequality, then we get,
x+y > -2
10 + (-1) > -2
9 > -2
That last inequality is a true statement since 9 is to the right of -2 on the number line. That means (10,-1) is a solution. Choice A is one of the answers.
Choices B and D are also answers for similar reasons.
Something like choice C is not a solution because
x+y > -2
-1+(-9) > -2
-10 > -2
Which is false.
You should find that choice E is false as well.
If you graphed the inequality and all of the points mentioned (see below), then you can visually confirm the answers. Notice how points A, B and D are in the blue shaded region which is the solution set.
The point E on the boundary does not count as a solution. This is due to the lack of "or equal to" portion of the inequality sign. That visually shows point E is not a solution. Point C isn't a solution either as it's nowhere near the blue shaded region.

Please excuse me if I am wrong but hope this helps
Answer:
Yes.
Step-by-step explanation:
Both outcomes are equally likely as he has a 50/50 chance of making a goal if there are no interruptions.
