Step-by-step explanation:
The first step is to find out what times 9 - 23 = 49 the first step would be to add 49 + 23 and that would get 72 so then you find that x would = 8 so the second step should be to put the problem together so 72 - 23 = 49. so basically x would equal 8.
Answer: The Median: 78, The First Quartile: 63, and The Third Quartile: 99
Step-by-step explanation: Ok, so let's put the data set from least to greatest....
(63, 63, 76,) (77, 79,) (84, 99, 99)
First Quartile Third Quartile
First, let's find the median, since you made a little mistake...
77 + 79 = 156
156 ÷ 2 = 78
The median is 78!
Now, let's determine the first quartile and the third quartile.
For the the first quartile/third quartile it'll be the middle number, if it's even we'll do the same extra step just like we'll do for the median. In this case it's not even therefore...
First Quartile: 63
Third Quartile: 99

Y = 3x - 1
The format for slope intercept form is:
y = mx + b
m represents the slope and that was given so:
y = 3x + b
Now we have to substitute the value from the given point into “y” and “x” to solve for “b”
(2) = 3(1) + b
2 = 3 + b
-1 = b
Now that we know b we can substitute it into y = 3x + b to get the equation of the line
y = 3x - 1
