Seventy-five percent of the medium-sized companies doing business in Brooklyn provide their CEO's with desktop computers. Moreover, 30% of
these companies provide a laptop given they have provided a desktop. What
is the probability that a CEO gets a desktop and a laptop?

Please help me out!

9/40

Step-by-step explanation: Multiply probability of getting desktop by probability of getting laptop.  3/4 (desktop)* 3/10 (laptop)=9/40(desktop &laptop) .  That fraction can't be reduced and is equal to .225 or 22.5%

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

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.
