Answer:
<h2>18mins</h2>
Step-by-step explanation:
This problem is on combined work rate
given that
Marta can vacuum the house in 30 min
then her rate= 1/30
Also, her daughter will take 45 min to vacuum the house
her daughter's rate will be = 1/45
then the combined work rate is
1/30+1/45=1/T
30+45/30*45=1/T
75/1350= 1/T
1/18=1/T
This means that they will both take 18 minutes working together to vacum a house
The answer that would best complete the given statement above is Z-SCORE. <span>When a data value is converted to a standardized scale representing the number of standard deviations the data value lies from the mean, we call the new value a Z-SCORE. Hope this helps.</span>
40/1 = 80/2 = 120/3 = 160/4 = 200/5 = 240/6 = 280/7 = 320/8 = 360/9 = 400/10 = 440/11 = 480/12 = 520/13 = 560/14 = 600/15 = 640/16 = 680/17 = 720/18 = 760/19 = 800/20
