Answer:
Step-by-step explanation:
The equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x +b y = b. Also ,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
Answer:
84
Step-by-step explanation:
when in numerical order,
68, 68, 79, 79, 84, 84, 84, 92, 92, 94
84 appears most often than any other number in the set.
Answer:
15P3 = 15!/ (15-3)! = 15*14*13*12! / 12! = 15*14*13
Step-by-step explanation:
When the seats are empty, there are a total of 15 people that can possibly sit in there. There will only be 1 person left.
When the 1st seat is taken there are now 14 people who can possibly sit on another chair. Same goes when 2 seaats are taken.
To find the total number of possibilities, we multiply together the possible number of people for seat 1, seat2, and seat 3.
Or, if we use stat, nPr = n! / (n-r)!
Meaning:
15P3 = 15!/ (15-3)! = 15*14*13*12! / 12! = 15*14*13
Answer:
t = 5(2) + 3
Step-by-step explanation:
You want the t on the outside because that is what you are trying to figure out.
You take the five, multiply it by 2, and then add 3 to what you get. Then thats the answer.
