Answer:0.0668
Step-by-step explanation:
As per given we have,
Also, the distribution is approximately normal in shape.
since ,
z-score corresponds to x= 73 will be :_
P-value =
Hence, the probability that this student is 73 inches (6'1") or taller = 0.0668
25/10 is the fully reduced version of 50/20 because odd integers can not be reduced any further
Answer:
P(1 dime then 1 nickel)= 15/208= 0.072115
or 7.2%
Step-by-step explanation:
No coin replenished.
total coins =65
P(1 dime then 1 nickel) = (20/65) * (15/64) =20 * 3 / (13 * 64) = 15/(13*16)
P(1 dime then 1 nickel)= 15/208= 0.072115
or 7.2%
Answer:
Step-by-step explanation:
Let's define our variables. Let a represent the number of adult tickets sold, s represent the number of senior tickets sold, and r represent the number of senior tickets sold.
We know that a total of 350 tickets were sold. So, the number of adult, student, and senior tickets sold must total 350. Therefore, we can write the following equation:
We know that each adult ticket costs $4, each student ticket costs $2.50, and each senior ticket costs $2. We are given that a total of $1095 was collected. Therefore, the number of tickets multiplied by their respective price must equal $1095. So, we can write the following equation:
Finally, we know that 40 fewer senior tickets were sold than student tickets. So, however many students tickets were sold, we can subtract 40 to get the number of senior tickets sold. Therefore:
So, our system of equations is:
And we're done!
