What is the probability of choosing a number 1 - 10 that is greater than 5 or even?
1 answer:
Answer:
70%
Step-by-step explanation:
So, first, our set of choices is 10. This means that there are 10 choices.
We want a number that is greater than 5 or even. Thus, let's mark down all of our choices.
Numbers greater than 5 are:
6, 7, 8, 9, and 10.
Even numbers are:
2, 4, 6, 8, 10.
However, we already counted 6, 8, and 10 previously, so we'll ignore that.
All in all, the following numbers will satisfy our requirements:
2, 4, 6, 7, 8, 9, and 10.
This is 7 out of 10 numbers.
Therefore, our probability is:

Answer:
The answer in the procedure
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
step 1
Find the slope between (-3, -2) and (1, 0)
Find the equation of the line
with m and the point (1,0)
substitute
step 2
Find the slope between (-2, -1) and (4, 2)
Find the equation of the line
with m and the point (4,2)
substitute
<em>Compare the equation of the two lines</em>
The two lines are parallel, because their slope is the same, but are different lines
therefore
Beatrice's conclusion is incorrect
All of these points are not on the same line, because are different parallel lines
The slope between (-2,-1) and (1,0) is equal to
