Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
A. 18.4
6 is c, i'm not entirely sure about 7
Answer:
Step-by-step explanation:
Seems like your question might be missing some parts.
If Not, Then
a line through the given points would have the form
y = mx + b
where m is the slope and b the y intercept
m = Δy/Δx = (-2 - 2) / (2 - (-2)) = -1
y = (-1)x + b
y = -x + b
now plugging in either point to find b
2 = -(-2) + b
b = 0
y = -x + 0
y = -x
Offer 2 is the best.
To find how much you get off of each car, multiply the amount by the fraction. For offer 2, do £11 100×⅓ and you should get 3700.
For offer 3 do £9600×¼ and you get 2400.
Since you get the most money off with offer 2, that would be the best offer.
Hope this helps :)
