Answer:
New mean=71.32
Step-by-step explanation:
The expression for the total initial score is;
T=M×S
where;
T=total initial score
M=mean score
S=number in the set
replacing;
T=unknown
M=72
S=17
replacing;
T=72×17=1,224
The total initial score=1,224
Determine the total score by;
total score=total initial score+total final score
where;
total initial score=1,224
total final score=(68+63)=131
replacing;
total score=1,224+131=1,355
Determine the new mean;
New mean=total score/new number
where;
total score=1,355
new number=(17+2)=19
replacing;
new mean=1,355/19=71.32
Difference between 25 and 35 = 35 -25
= 10
Then
percentage by which 25 is less than 35 =(10/35) * 100
= (2/7) * 100
= 200/7
= 28.57 percent
So 25 is 28.57% less than 35.This is the only clear way of solving these kind of problems. I hope you
have understood the method used to solve this problem. Hopefully you
can do such type of problems without needing any help.
Answer:
Explanation:
Build your conversion factors using the conversion table:
From the prefixes used in the metric system, you know that 1 deciliter = 0.100 liters. Then:
Arrange the expression to simplify the units and convert from cups to deciliters:
Round to the nearest tenth: 0.2 deciliter.
Answer: There isn't a possible way you can really answer this question because I don't know how much one piece cost in the first place , but if I had to guess I would say around 50-80 dollars for a cake is enough for 57 guests.
explanation: I say this because I know usually cakes for a decent amount of people are around 50-80 dollars.
