Answer:
(a) Dahl Motors = 8 Cars
Farthington Auto Sales = 7 Cars
(b) Roger will purchase from Farthington Auto Sales with higher weekly profit
Step-by-step explanation:
Dahl Motors / Week
(1) Car Sold 5 6 7 8 9 10 11 12
(2) Probability 5% 9% 14% 24% 18% 14% 11% 5%
(3) (2 x 3 ) 0.25 0.54 0.98 1.92 1.62 1.40 1.21 0.60
(4) Average sales = 0.25 + 0.54 + 0.98 + 1.92 + 1.62 + 1.40 + 1.21+0.60
= 8.52 cars/ week
= 8 cars /week
Profit/ Car = $544
Total weekly profit = 544 x 8
= $4,352
Farthington Auto Sales/ Week
(1) Car Sold 5 6 7 8 9 10
(2) Probability 8% 21% 31% 24% 10% 6%
(3) (2 x 3 ) 0.40 1.26 2.17 1.92 0.9 0.6
(4) Average sales = 0.40 + 1.26 + 2.17 + 1.92 + 0.90 + 0.60
= 7.25 cars/ week
= 7 cars/week
Profit/ Car = $651
Total weekly profit = 651 x 7
= $4,557
From the calculations above , Roger will purchase from Farthington Auto Sales
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
The mean, median, and mode are equal to 1. So among the choices, the first one is correct - mean = mode
Mean - an <em>average </em>of the given set of number; to find this, add the numbers and divide it by 11 (the number of given data)
= (-1 + -1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3) / 11
= 1
Median - the <em>middle or center</em> of the given set; to find this, arrange the numbers in numerical order, then get the center or middle number as the median
= <span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
= [</span><span>-1, -1, 0, 1, 1,] <u>1</u>, [1, 2, 2, 2, 3]
Mode - is the value that occurs most of the time in the given set; so obviously <em>number 1 occurred four times</em> so 1 is our mode
