Answer:
The 2 numbers are 158 & 199
Step-by-step explanation:
Let 1st no. = x
2nd no. = y
x + y = 357 -----(1)
x - y = 41 ------(2)
(1)-(2)
2y = 316
y = 158
suby=158into(1)
x + 158 = 357
x = 199
Answer:
Total number of students = 50 students.
Step-by-step explanation:
Total number of books = number of books * frequency
1 * 3 = 3
2 * 5 = 10
3 * 12 = 36
4 * 25 = 100
5 * 4 = 20
6 * 1 = 6
Total number of books = 3 + 10 + 36 + 100 + 20 + 6
Total number of books = 175 books.
Now, to find the total number of students;
Total number of students = summation of frequency
Total number of students = 3 + 5 + 12 + 25 + 4 + 1
Total number of students = 50 students.
slope = rise / run = (-3 - -1) / (-1 - -1) = 2/0
The slope is infinite The graph is a vertical line.
