Answer:
A, (1, 3+1/2)
Step-by-step explanation:
Midpoint formula for reference: m= {(x1 + x2)/2, (y1 + y2)/2}
Plugging in the points we get: m= {(8 - 6)/2, (5 + 2)/2}
Now we simplify using PEMDAS. First step is parentheses.
m= {2/2, 7/2}
Simplifying again (and making 7/2 a mixed number), it becomes
m= {1, 3+1/2}
Hope this helps!
Answer:
B
Step-by-step explanation:
Initial mean = 156, Changed mean = 163.92
So, mean increases. Only condition that satisfies this is B.
Answer:
Step-by-step explanation:
3 out of 12 children at the day care center are 5-year-olds. So, the probability of a randomly selected child being a five-year old is 
, or .
$4/3=$1.33 per pound.
$9/8 = $1.13 per pound.
The second one is cheaper.
The median is the middle number. The median of 18 and 16 would be 17.
18 17 16...therefore 17 is the middle number.
