To read the line plot in order to answer this question, you will need to understand that each X above the numbers represents the number of hours 1 student studied. If you count the total number of Xs, that would represent the total number of students surveyed.
The number of students that studied at least four hours, would be the number of Xs that are at 4 or above. This means there were 4 students that studied for hours or more.
Answer:
The volume of the larger cube is 
Step-by-step explanation:
Let
x ---> the length of the smaller cube
y ---> the length of the larger cube
we know that
the volume of a cube is equal to

where
b is the length side of the cube
we have
----> equation A
The volume of the smaller cube is 216 cm^3
so
substitute in the formula of volume

solve for x
![x=\sqrt[3]{216}\ cm](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B216%7D%5C%20cm)

<em>Find the value of y</em>



<em>Find the volume of the larger cube</em>

substitute the value of y


Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.

Step-by-step explanation:
From the question x is the number of stools and y is the number of recliners
Given that the coffee shop can hold no more than 50, then the inequality for number of seats will be;
x+y≤ 50
Also, the owner wants at least 20 of the seats to be stools, this can be written as;
x≥20
Using a graph tool to visualize the inequalities, you get the attached graph;
