3x and 2x
Step-by-step explanation:
Answer:
20 days
Step-by-step explanation:
Number of books sold each day for 40 days :
The first quartile (Q1) = 2
For the 25% of the days = 2 books were sold
Hence 0.25 * 40 = 10 days, 2 books or less were sold
The upper quartile (Q3) = 12 books
For up to 75% of the days = 0.75 * 40 = 30 days ; 12 books or less were sold
To obtain the number of books sold between 2 and 12 ; we subtract :
(30 days - 10 days) = 20 days
Answer: (3.075, 0) and (0, -4.1)
<u>Step-by-step explanation:</u>
4x - 3y = 12.3
x-intercept: 4x - 3(0) = 12.3 ⇒ 4x = 12.3 ⇒ x = 3.075
(3.075, 0)
y-intercept: 4(0) - 3y = 12.3 ⇒ -3y = 12.3 ⇒ y = -4.1
(0, -4.1)
It’s A and B hope this helps :)
