6.25 lbs. 1
5.50 / 6.25 = $.88
We can say that exchanging one couple's ticket for an individual's ticket would increase the money in the cash box from 200 to 202 and it would result in an even number of couples tickets sold.
<u>Step-by-step explanation:</u>
Let the number of tickets sold to the individuals = s
Let the number of tickets sold to the couples = c
According to the question,
s + c = 46 ( Equation 1)
Since each individual's ticket is $6, the total amount of money made by selling tickets to individuals is 6s.
Similarly, since each ticket sold to couples is $8, the total amount of money made by selling tickets to couples is 8c.
So,
6 s + 8 c = 200 ( Equation 2)
On solving both the equations, we get
c = 38 and s = 8
Therefore, 8 tickets were sold to individuals and 38 tickets were sold to the couples.
Answer:
you would accept the hypothesis that the usual load is 13 credits.
Step-by-step explanation:
Here 13 is the first Quartile, i.e 25th percentile
we would accept the hypothesis that the usual load is 13 credits. Therefore, Since it is reasonable not to reject the hypothesis, you would accept the hypothesis that the usual load is 13 credits.
Do the following
find a common denominator 5x8=40
get all your denominator values the same
next solve
(5×15)+(8×2)+(5×(-7))/(40)
so you get this next
75+16-35/(40)
then you have
56/40
which reduces down to
7/5
