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.

Answer:
0.52
Step-by-step explanation:
Given the regression line :
Test score^ = 698.9 - 2.28STR
T statistic on slope Coefficient = 4.38
The standard error on slope Coefficient :
2.28 / 4.38
= 0.5205479
= 0.52
Median-the middle number in a set of data
Mean-the average of a set of data
Mode-the number that occurs most often in a set of data
Outlier-a number that is much bigger or smaller than the other numbers in a data set
I’m so sorry if it’s wrong-
Answer:
