Hello! To answer this question, all you have to do is divide the amount traveled by the speed per second. 200/5 is 40. It would take 40 seconds to travel 200 meters.
Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
Using conditional probability, it is found that there is a 0.12 = 12% probability that a student gets an A in Algebra 2 and does all their assignments.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a <u>previous event</u>. The formula is:
In which
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: Student gets an A in Algebra 2.
- Event B: Student completes all the assignments in Algebra 2.
The probabilities are:
- The probability that a student gets an A in Algebra 2 is 0.2, hence .
- The probability that a student completes all the assignments in a Algebra 2 is 0.5, hence .
- The probability that a student does all their assignments given that they get an A in Algebra 2 is 0.6, hence .
We want to find , hence:
0.12 = 12% probability that a student gets an A in Algebra 2 and does all their assignments.

That makes no sense for a question.
GCF is 2x so we have
= 2x(4x^2 + 12x + 9) The expression will factor as follows:-
= 2x ( 2x + 3)^2 Answer
