Step-by-step explanation:
mean : added up the values and divide the result by the number of the values
Mr Jones = (5 + 6.25 + 5.75 + 6.50 + 8)/5 = $6.30
Mrs Jones = (5.50 + 7 + 6.25 + 5.75 + 7.75)/5 = $6.45
The difference between the two mean is 15 cents or $0.15
Answer:
exact form: 2 ^3√2
Step-by-step explanation:
Answer:
1. The angles of a triangle added up all together is 180. So, we can solve a as an equation!
36+57+a=180.
From this, we can figure out a:
a=87
2. The same goes for this one, just a bit different. We write our equation like this:
3x+90=180
we solve this:
3x=90
we divide both sides by 3 and get:
x=30
