Answer:(-6.5,-5)
Step-by-step explanation:
P = (3A +1B)/(3+1)
P = (3(-7, -9) +(-5, 7))/4 = (-21-5, -27+7)/4 = (-6.5, -5)
Outta Luck Towing Company charges $50 to hook a vehicle to the truck and $2.75 for each mile the vehicle is towed.
Let the number of miles towed is m, and the total charges is c
2.75 for each mile the vehicle is towed
for 1 miles , the charge is 2.75
For m miles , the charge is 2.75m
$50 to hook a vehicle to the truck. so basic charge is 50
Total charge = charge of m miles + basic charge
C = 2.75 m + 50
Answer:
chairs at each table
Step-by-step explanation:
Total number of chairs : 300
Total number of tables : t

Answer:
Mean: 68.8.
Median: 77.5
Mode: 80, 90
Step-by-step explanation:
-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90 = 688. Then divide by 10 because there are 10 numbers.
-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90
(75, 80) are the middle numbers, so add them both, then divide by 2.
80, 90 appear more than the other numbers.
Range is highest - lowest. 90 - (-7) = 97, or it could be 83. I don't know.
It would take 5 yrs. for both trees to be the same height.
