Let a,b,c,d and e are five numbers
mean = (a +b+ c+ d+e)/5 = 30
⇒ (a +b+ c+ d+e) = 150_______(1)
now, Let the number excluded be a
then, new mean = (b+ c+ d+e)/4 = 28
⇒ (b+ c+ d+e)= 112
putting this value in (1),
⇒a + 112 = 150
⇒a = 150 -112 = 38
excluded number = 38
Step-by-step explanation:
6 percent of 350 is 21. 21 plus 350 is 371, therefore the answer is 371.
Brainliest? :)
Square root means 46225^1/2 so the answer is 65
54 and 21 and thats how i got it lol
