Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students
Answer: A.
The system is consistent because the rightmost column of the augmented matrix is not a pivot column.
Explanation: a system is consistent if and only if the rightmost column of the augmented matrix is not a pivot column. Since every column of the coefficient matrix is a pivot column, none of the leading coefficients are in the rightmost column of the augmented matrix. Therefore the rightmost column of the augmented matrix cannot be a pivot column and the system must be consistent.
Answer:
141
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
We know z+70 = 180 since they form a straight line
z = 110
z = 1/2 ( 79+w)
110 = 1/2 ( 79+w)
220 = 79+w
220-79 = w
141 =w
