To find the mean of this set of data you must add all the numbers together, then divide by the numbers that you have. Since you have 5 numbers you would divide by 5 after adding them together.
1st: ADD!!
20 + 12 + 29 + 15 + 49 = 125
2nd: divide by 5!
125 ÷ 5 = 25
So the mean of this data set is 25.
Good Luck! :)
Recall that the roman numeral "L" has a value of 50. Meanwhile, the value of "XL" is L - X = 50 - 10 = 40. Comparing their numerical values, we have 50 > 40 or L > XL. This means that in Roman numeral, we find that L is actually larger than XL.
Thus, the answer is<span> in Roman Numerals.</span>
I believe it is d also hope that help
Follow PEMDAS.
You would first do your distributive property which is, -5(z+2). You would multiply -5 to z and -5 to 2 which will give you -5z + -10.
so now you have 2z-5z+ -10= -8 - 2z. Now you must isolate the variable. So subtract -8 to -10 which will give you -18.
Now you have the equation 2z-5z-18=-2z
Now combine like terms. 2z-5z= -3z
Now you have the equation -3z-18=-2z
Now you must move the -3z to the other side of the equal sign by adding the opposite which is +3z to -2z which will give you +1z
Now you have -18= 1z
Now you divide. -18 divided by 1 is -18.
So your final answer will be -18=z
The first option is greater.
