41) you have a 40 day period
two visits with +75 centimeter growth each
3 visits with +6 each
in total 2*75+3*6=150+18=168
divide this by 40 days to get the average: 168/40=4.2 centimeters per day or 1.65 inches/day
42)
7x total
3x20
2x15
1x13
1x16
if you order these into a list:
13,15,15,16,20,20,20
the median is the middle value, in this case 16$
the mode is the most common value: 20$ which exists 3 times
X^2+ (y+8)^2 = 81.....this is C.
X^2 + y^2 + 16y +64=81 so x^2 + y^2 + 16y = 17.....this is D.
So I’d say C and D are correct
Answer:
C
Step-by-step explanation:
The closest number I can find to the answer is 18 cents per unit but at 18 cents per unit, the cost for 24 units would be $4.32. and at 17 cents per unit, the entire case of 24 units would then cost $4.08 which is too low so either way, there is no exact answer but 18 cents per unit is the closest to the correct answer
hope this helps
