Answer:
I think 7 days for 7 cups.
Step-by-step explanation:
Answer:
Step-by-step explanation:
m=marta's rope
d=dilbert's rope
3d-10=m
m+d=120
Then you can substitute equation 1 into the second one
(3d-10)+d=120
3d-10+d=120
4d-10=120
4d=130
d=32.5
m+d=120
m+32.5=120
m=120-32.5
Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.
I believe this is the solution.
First we need to identify if the data is qualitative or quantitative.
The data is average number of people living in the homes.
Qualitative data as its name indicates is an attribute or characteristic. It can not be measured e.g color. Quantitative data is such a data which can be counted or measured.
Since the average number of people can be counted and measured, the data is Quantitative.
In an observational study the individuals are observed. In the given case, Kira did not observed the individuals to gather the data, rather she used an Online resource to gather the data.
Therefore, the correct answer will be:
Kira used published data that is quantitative.
