Answer:
Here is the correct answer. I just took the test.
Step-by-step explanation:
Answer: We are missing some data here, but it appears to be a right triangle question. Assuming that triangle ABC is a right triangle, the measure of angle B would be about 63.26 degrees.
If you draw a right triangle ABC with the given information, you will see that we have an adjacent side and hypotenuse with regard to angle B.
Therefore, we can write and solve the following cosine ratio.
cos(B) = 9/20
B = 63.26 degrees
1. -7(6v+4)+3v(v+3)
-42v-28+3v ²+9v
-33v-28+3v ²
=3v ²-33v-28
2. -3k(2k-3)+7(k-7)
-6k ²+9k+7k-49
= -6k ²+16k-49

Answer:</u></h3>
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
<h3><u>
Step-by-step explanation:</u></h3>
Let A denote the event of rolling a number less than 5 in a six-sided die.
Now, we know that the Total outcomes are: 6
since, the sample space is given as: {1,2,3,4,5,6}
Also Number of favorable outcomes are: 4
since the numbers which are less than 5 are {1,2,3,4}
Now we have to find:

where P denotes the probability of an event and
denote the complement of event A.
We know that:

Now,

Hence,

Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
I belive this would equal -11/2.
hope this helps!
