Mean is the average number of calls to get this add them all together and divide them by the total number of days 4+2+6+5+0+3+9=29 then divide by the total number of days (8) so this person receives around 3.625 phone calls each day which rounds up to 4 I'm 90% positive this is right hope this helps
Answer:
25/10
Step-by-step explanation:
Make the fractions improper by multiplying the whole number by the denominator and then adding the numerator (if this makes sense).
This makes 5x10=50+3=53/10
Do the same for the second fraction. 2x5=10+4=14/5
Then make the denominators the same, and in this case all you need to do is multiply both sides of 14/5 by 2, so that makes 28/10.
Now, just take it away.
53/10-28/10=25/10, which can be then simplified into 2 1/2 or 5/2.
The equation is 1.2t=50.2 And the solution is 42
