Answer:
m=9t
Step-by-step explanation:
to figure out how much money you earned, you have to multiply how long you worked by the amount you get paid
The answer is 1.5 bc 0.75 times 2 since it’s the midpoint
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
