Solution :
In the figure, the box plot represents the lengths of the songs of the two digital music players that is in minutes.
From the figure, we can see that for the music player Y, the interquartile range of the data is small.
And the interquartile range of data is more for the music player X.
So, we can conclude that the interquartile range of data is greater for Music player X than the interquartile range data of music player Y.
Answer: she had 98 flowers
Step-by-step explanation: (4+3)x(7x2)
Answer:
The percentage error is;
A. 1.79%
Step-by-step explanation:
The given parameters of the rectangular field are;
The length of the field = 62 feet
The width of the field = 25 feet
The width of the gate of the fencing = 9 feet
The actual length of fencing Pete used to fence the field, P₁ = 168 feet
The length of the fencing required in the design, 'P₂' is given as follows;
P₂ = 62 ft. + 62 ft. + 25 ft. + 25 ft. - 9 ft. = 165 ft.
The difference between the actual and design length of fence measurements = P₁ - P₂ = 168 ft. - 165 ft. = 3 ft.
The percentage error in the design measurements compared to the actual fence material used, % Error, is given as follows;
Therefore;
∴ The percentage error of Pete's design measurements compared to the actual fence material used, % Error ≈ 1.79 %.
Answer:
1. (7,-9)
2. (4,0) and (10,0)
3. (3,0) and (-3,0)
4. (0,-9)
5. (-1,-32)
Step-by-step explanation:
To find the vertex use the formula
First make the equation into a quadratic equation.
Now it is in the form
Now we can substitute the values
Now we have 7 as our x value for the vertex we can substitute for y,
So the vertex for 1 is (7,-9)
To find the intercepts for 2 & 3, they basically already give it to you. You just need to find a value for x for x-4 that will equal it to 0 and another for x for x-10 that will equal it to 0.
4 is slightly different but start the same,
Here, c (9) just shows the graph move down 9, so the y intercept = 9.
5 is the same process as 1,
Vertex,
Substitute,
So the vertex is (-1,-32)
Answer:
Yes
Step-by-step explanation:
Because he spent 3.50 in those two days and he will spend 3.50 in 6 days. 3.50×6= 21.
