Find the area of the star part:
- 5.4 × 7.5 = 40.5
Find the area of the whole flag:
- 19 × 10 = 190
Subtract the two to find the area of the striped part:
- 190 - 40.5 = 149.5

Answer:
17/300.
Step-by-step explanation:
17/300 students have a dog.
For this case we have the following system of equations:
We can Rewrite the system of equations of the form:
Where,
A: coefficient matrix
x: incognita vector
b: vector solution
We have then:
Then, the determinant of matrix A is given by:
Answer:
The determinants for solving this linear system are:
Answer:
57
Step-by-step explanation:
There are 60 data altogether.
Therefore, n=60
50th percentile = 50%*(n+1)
=50/100*(60+1)
=30.5
This implies that the 50th percentile is between the 30th and 31st data
30th data= 57 ; 31st data = 57
since they are the same figure, 50th percentage = 57
