Answer: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Find:
You can see that vectors and This means that opposite sides are parallel and option B is false.
Find the lengths of all sides:
As you can see the lengths of opposite sides are equal, but all lengths are not equal. Therefore, the last option D is false.
Now check whether angles A and B are perpendicular:
The dot products are not equal to zero, then angles A and B are nor right. This means that option C is false and option A is correct (ABCD is a parallelogram with non-perpendicular adjacent sides
AKA your correct awnser choice is A :)✨
Another way to write the expression the answer is this (t.14)-(t.5)
Answer:
y = (1/3)x + 1
Step-by-step explanation:
You first find the slope:
(2 - (-1))/(3 - (-6)) =
3/9 =
1/3
This means the equation of the line is y = (1/3)x + b, where b is a real number.
Plug in either of the points to find the value of b:
-1 = (1/3)(-6) + b -->
-1 = -2 +b -->
1 = b
This means the equation is y = (1/3)x + 1
Answer:

Step-by-step explanation:
Assuming this problem :"Only 30% of the students in a certain liberal arts college are males.
If two students from this college are selected at random, what is the probability that they are both males?"
Previous concepts
An independent event is an "event that has no connection to another event's chances of happening ". For this case we can assume that if one person is male and if we select another one the probability that this one would be male or female is totally indepedent from the first selection.
When we have two independent events let's say A and B and we want to find the probability that both events occurs at the same time we can use the following formula:

Solution to the problem
We can define some notation:
first person selected is a male
second person selected is male
On this case we want the probability that both would be males. And we can express this like this on math terms:

For this case we can assume that the two events are independent. And in order to find the probability for two events independents events we just need to multiply the probabilities of each one like this:

It’s using the distributive method. 7 x a is 7A and 7 x 13 is 91, therefor it is 7A+91.
