The sum total of the samples= 165
Number of years= 3
The average= total/number of years
The average= 165/3
The average= 55

Answer:
-1.409
Step-by-step explanation:
I’m assuming this a z-score for stats. You would just go into your calculator, in my case a Casio. Then, you’d press on the stats module, click F5 (DIST), F1 (NORM), F3 (InvN). You would change the data to variable, then put in tail right, area .9207, SD 1, mean of 0. Then hit execute and you’ll get the answer of -1.4097958. Round it if needed.

Answer:
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
Step-by-step explanation:
6x + 4x = 700
10x = 700
x = 700/10 = 70
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
I hope im right!
