Answer:
Step-by-step explanation:
Given that Prof Liu gave the same quiz to the students in her morning class and in her afternoon class. the average score for the two classes combined was 84.
(1) The average score for the students in the morning class was 80
(2) the average score for the students in the afternoon class was 86
Let m be the no of students in I class and n in II class
Total of I class = 80m and
Total of II class = 86n
Total of both classes = 80m +86n
Average =
m cannot be equal to n because in that case average would have been 83
If m >n, then say n =m+a
then average = 
Because 86 is more times added, average score would decrease hence we would not get 84.
So I class is getting less score of 80 to get a score average of more than 83 (the average) the class II should have more students.
Answer:
the answer is 4w-14=14 w=7
Answer:
The answer to your question is: the second option
Step-by-step explanation:
a) This is not the right answer, the sentence to this option could be: fourteen more than the quotient of five and a number is 23.
b) This is the right option, the sentence is given in the description.
c) This is not the right answer, the sentence to thi option could be: the quotient of fourteen plus a number and five is 23.
d) This is not the right answer, the sentence of this option could be: the quotient of five and the addition of a number and fourteen is 23.
Answer:
Option C. exponential decay function
Step-by-step explanation:
In this problem we have a exponential function of the form
where
y ---> is the money that is in the bank
x ----> number of days
a ---> is the initial value or y-intercept
b is the base of the exponential function
r ---> is the rate of change
b=(1+r)
In this problem we have that
Each day 1/2 of the money that is in bank value is removed
so
---> is negative because is a decreasing function
The value of b is equal to
The value of b is less than 1
b<1
That means -----> Is a exponential decay function
If there are 4 people and you want the time for EACH person then you would do 62.59
Which = 15.6475
