Ou paint 1/3 of a wall in 1/4 hour. At that rate, how long will it take you to paint one wall? rate = (area/time)
------
rate = (1/3)/(1/4) = 4/3 job/hr
-----
time for job = 3/4 hr/job = 45 minutes to do the whole job.
1100 miles
this is because u first have to find the miles she drove in january. since she drove 3 times as much in march than in january, u divide or 825 divided by 3 to get 275. since she drove 4 times as much in february of january, u multiply 275 by 4 to get 1100.
hope this helps! :)
3x+33=10x+47 -> -14=7x so x=-2
Answer:
The correct option is (b) 0.333.
Step-by-step explanation:
The data provided is as follows:
Hepatitis C No hepatitis C Total
No Tattoos 5 50 55
1 Tattoo 10 210 220
> 1 Tattoo 15 150 165
Total 30 410 440
The probability of an event <em>E</em> is the ratio of the favorable number of outcomes to the total number of outcomes.
The condition probability of an event <em>A</em> provided that another event <em>X</em> has already occurred is:
The number of people who has hepatitis C is:
n (Hepatitis C) = 30
The number of people who has hepatitis C and one tattoo is:
n (Hepatitis C and 1 Tattoo) = 10
Compute the probability that he or she has hepatitis C, given that he or she has one tattoo as follows:
Thus, the correct option is (b).
-2976 use formula a_1 + (n-1)d n = term number ( in this case 1000)
