23. Tell whether the sequence is arithmetic. If it is, what is the common difference? (1
-15, -9, -3, 3,
Oyes; 3
Oyes; 5
Oyes; 6
Ono

  O Yes; 6

Yes it is Arithmetic;  the difference is 6

Step-by-step explanation:

If the numbers keep changing by the same value being added or subtracted, it is Arithmetic.

-15 - (-9) = -6    -9 - (-3) = -6    -3 - 3 = -6

"Same difference"  as the saying goes!

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
