Answer:
A & B
Step-by-step explanation:
5x - 2y = 10 (1)
-2.5x + y = -5 (2)
When you multiply (2) by -2, you get (1), so there can be many solutions
To choose from the given options, plug in the values to check which ones satisfy the equation
5x - 2y = 10
A) (2,0)
5(2) - 2(0) = 10
10 = 10 (true statement)
B) (-2,-10)
5(-2) - 2(-10) = 10
-10 + 20 = 10
10 = 10 (true statement)
1 yard is 36 inches
so 5 yards are 180 inches
1 hour is 60 minutes
so in 60 minutes she paints 180 inches
or in 1 minute she paints 3 inches
Answer:
If the game with 3 hits is ignored the data becomes:
- 7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11
a) The mean will increase.
<u>With 3:</u>
- (3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9
<u>Without 3:</u>
- (7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21
b) The median will remain as is.
- With 3 and without the median is same = 9
