Answer:
Step-by-step explanation:
#1
y= 17
#2
y= 1/2
#3
y= -1 3/4
#4
y= -83/5
First put the numbers in order to find the median:
26, 27, 28, 32, 32, 33, 35, 36, 38, 40, 42, 48
The number in the middle will be the median. In this case, there is an even number of data points so we will have to average the two numbers in the middle:
33 + 35 = 68...68/2 = 34. Therefore the median is 34
Now to get the inequality, add and subtract 6 from 34:
34 + 6 = 40
34 - 6 = 28
So the inequality is:
28 < x < 40
You need to figure out how many hours does he need to read one book.
8.5 / 4 = 2.125
Hope this helps! (:
Y - y1 = m(x - x1)
slope(m) = -1/7
(3,3)...x1 = 3 and y1 = 3
now we sub
y - 3 = -1/7(x - 3) <==
Answer: $160
Step-by-step explanation:
You'll need to find the mark-up price first: $2400+1/3
1/3= $800
$2400+$800= $3200
$3200 is the mark-up price
Then you have to find the discount:
1/5 of $3200
$3200/5= $640
$3200-$640= $2560
Lastly, you have to find the profit:
$2560-$2400= 160
