Answer:
0.6 = 60% probability that he or she studies on a weeknight.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Probability A: Probability of a student studying on weeknights.
Probability B: Probability of a student studying on weekends.
Forty-two percent of students said they study on weeknights and weekends
This means that
47% said they studied on weekends
This means that
65% said they study either on weeknights or weekends.
This is
If you were to pick one student at random, what is the probability that he or she studies on a weeknight?
This is P(A), and the equation used is:
Considering the values we have:
0.6 = 60% probability that he or she studies on a weeknight.
<u>Note: </u><u><em>Your option 'b' is somewhat ambiguous, so I am assuming you meant to write the equation y=2x+3 for the 'b' option.</em></u>
Answer:
the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).
Step-by-step explanation:
- An equation parallel to the given line equation will have the same slope.
Given the point (2, 7) from which the equation passes through.
so checking all the equations in the options to check whether any equation passes through or not.
Checking the option 'a':
y = 3x - 2
Putting (2, 7)
7=3(2)-2
7=6-2
7=4
L.H.S is not equal to R.H.S
Therefore, the option 'a' is NOT correct.
So, the equation y = 3x - 2 will NOT PASS through the point (2, 7)
Checking the option 'b':
y = 2x + 3
Putting (2, 7)
7=2(2)+2
7=7
7=7
L.H.S is equal to R.H.S
Therefore, option 'b' is the CORRECT option.
So, the equation y = 2x + 3 will PASS through the point (2, 7)
Checking the option 'c':
y = x-6
Putting (2, 7)
7=2-6
7=-4
L.H.S is not equal to R.H.S
Therefore, the option 'c' is NOT correct.
So, the equation y = x-6 will NOT PASS through the point (2, 7)
Checking the option 'd':
y + 2x = 8
Putting (2, 7)
7+2(2)=8
7+4=8
11=8
L.H.S is not equal to R.H.S
Therefore, the option 'd' is NOT correct.
So, the equation y + 2x = 8 will NOT PASS through the point (2, 7)
Therefore, considering the above analysis, we conclude that:
Option 'b' is the CORRECT option.
So, the equation y = 2x + 3 will PASS through the point (2, 7).
also
The slope-intercept form of the equation is
where m is the slope and b is the y-intercept.
Therefore, the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).
