coordinate of B= (2+3,0) = (5,0)
by pythagoras' theorem,
height of triangle^2 + half length of AB^2 = AC^2
height of triangle^2 = 3^2-1.5^2
height of triangle ^2= 6.75
height of triangle= √6.75
coordinates of C= (1.5,√6.75)
1. Set up the long addition.
2 4 7
+3 5 8
_______
2. Calculate 7+8, which is 15.
since 15 is two-digit, we carry the first digit 1 to the next column.
1
2 4 7
+ 3 5 8
________
5
3. Calculate 4+5, which is 9. Now add the carry digit of 1, which is 10. Since 10 is two-digit, we carry the first digit 1 to the next column.
1 1
2 4 7
+ 3 5 8
________
0 5
4. Calculate 2+3, which is 5. Now add the carry digit of 1, which is 6.
1 1
2 4 7
+3 5 8
______
6 0 5
5. Therefore, 247 + 358 = 605.
605
c) opposite edges of a computer screen
Answer:
Sample 1 : independent
Sample 2 : dependent
Step-by-step explanation:
From the question we are told that
The given date is
Sample 1: Pre-training blood pressure of 17 people
Sample 2: Post-training blood pressure of 17 people
Now Sample 1 is independent because the Pre-training blood pressure of 17 people does not depend of Post-training blood pressure of 17 people
While
Sample 2 is dependent because the Post-training blood pressure of 17 people is dependent on the Pre-training blood pressure of 17 people
