Well first you need to find the LCM (least common multiple) of 4 and 6 (the denominators) so that you can subtract them from each other.
4: 4,8,12,16,20
6: 6, 12, 18, 24
The LCM is 12.
Now we can subtract the two mixed numbers by turning them into improper fractions.
5 3/12 -> 27/12
3 10/12 -> 42/12
42-27=15
The fraction is 15/12, which simplifies into 1 1/4.

Step-by-step explanation:
for this equation
a=3
b= -5
c = -7
The sum of equal to

and the product is equal to

. All you do is replace the values. You can prove both of those using the quadratic formula.
Bill does because if you multiplie 10x2=20 and Val only ran 4 1/2
Answer: There is a probability of 65% who showed up for an appointment.
Step-by-step explanation:
Since we have given that
Percent of people who do not show up for their appointment = 35%
Percent of people who show up and completer the study = 55%
Percent of people who show up but do not complete the study = 10%
Probability of showing up for an appointment is given by

Hence, there is a probability of 65% who showed up for an appointment.
