Explanation:
The original set
{78, 55, 22, 16, 84, 75, 33, 69, 58, 59}
sorts to
{16, 22, 33, 55, 58, 59, 69, 75, 78, 84}
The min and max are 16 and 84 respectively
Midrange = (min + max)/2 = (16+84)/2 = 50

Answer:
I think it's B
Step-by-step explanation:
2x=10
7x-14=21
x=5
2x=10 (divide both sides by two)
2x/2 10/2
<u>x=5</u>
x = 0, y = 1
2x + 6y = 6 → (1)
x - 3y = - 3 ( add 3y to both sides )
x = 3y - 3 → (2)
substitute x = 3y - 3 into (1)
2(3y - 3) + 6y = 6 ← distribute parenthesis and simplify left side
6y - 6 + 6y = 6
12y - 6 = 6 ( add 6 to both sides )
12y = 12 ( divide both sides by 12 )
y = 1
substitute y = 1 into (2)
x = 3(1) - 3 = 3 - 3 = 0
solution is x = 0 , y = 1
