A histogram is used to show the frequency of data, where the length of the bar represents the frequency.
<em>From the histogram, 50 students drank the recommended amount of water. </em>
Given that
or more
The number of students who drank the recommended amount are students whose frequency is at least 48
From the attached histogram, only 1 bar has a frequency that is at least 48 or more
And the number of students in this bar is: 50
Hence, 50 students drank the recommended amount of water,

Answer:
A
Step-by-step explanation:
This is how I write
y=kx+m
but I have seen some write it like this:
y=mx+b
Well both of them are the same thing, I'll use the first one because I'm more comfortable with it.
y=kx+m
To find out what k
So you first need to choose two points.
I'll go for (0,-5) and (2,0)
Now you could insert k into the equation and it will look like this.
To find out what m is just pick one point and insert it into the equation. So if I pick (0,-5). 0=X therefore it should be replaced by x and -5=y therefore it should also be replaced by y.
m=-5
Try it with another point to see if you get the same answer. this time I'll pick (-6,10)
m= -5
The equation will be y=-5/2x-5)
