Answer:
41
Step-by-step explanation:
40+16+y=180°
56+y=180°
y=180-56
y=124°
124+15+x=180°
139+x=180°
x=180-139
<em>x=41°</em>
Answer:
The more effective way for this data set is the mean.
Step-by-step explanation:
The median required arranging the numbers in an descending-to-ascending order, and it is also preferred if the quantity of the numbers to be an odd number.

Answer:
There are 21 twenties and 8 fifties in the drawer.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of twenties
y is the number of fifties.
A cash drawer contains 29 bills.
This means that x + y = 29.
The total value of the bills is $820.
This means that 20x + 50y = 820.
So
x + y = 29
20x + 50y = 820
From the first equation, x = 29 - y. So:
20x + 50y = 820
20(29 - y) + 50y = 820
580 - 20y + 50y = 820
30y = 240
y = 8
And
x = 29 - y = 29 - 8 = 21
There are 21 twenties and 8 fifties.
