A clothing design company pays two different people to design its T-shirts, The company pays person A $10 an hour and pays person B $12. Person A
cannot work more than 5 more hours than person B, but they cannot work
more than 30 hours total. Person A makes the company a profit of $15 an
hour, and person B makes the company a profit of $20 an hour. If the
company wants to make at least $250 in profit, which value will minimize the
cost to the company? (Each point is (a, b), where a is the hours person A
works and bis the hours person B works.)
A. (10,20)
B. (17.5, 12.5)
C. (0,30)
D. (0, 12.5)

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
