Answer:
The son is 5 I think
Step-by-step explanation:
24+3=27
27 divided by 5 = 5.4
round 5.4 to 5 since it is under .5
and you get 5
Answer:
3.5 = x + 4*y
4 = 2x + 2*y
Step-by-step explanation:
The total distance ran by Avi is the sum of the distance from his house to the track, and the total distance ran in the tracks (that is, the distance of one lap times the number of laps Avi ran).
If we call 'd' the total distance and 'k' the number of laps, we have the equation:
d = x + k*y
So with the data given, we can have the following system:
3.5 = x + 4*y
4 = 2x + 2*y
In the second equation, we have 2x because Avi ran from his home to the track, and in the end ran back home, so Avi ran the distance x two times.

Step-by-step explanation:
Given that:
Maximum capacity of hard drive = 500 GB
Space used up = 58 GB
Size per movie = 8GB
Number of movies = x
1)
[(Number of movies * size per movie) + used up space] should be less than or equal to the maximum capacity to f the drive.
From Elena's inequality, the total space taken up by movies + used up space is greater than total capacity of hard drive.
That is ;
[(8x + 58 ≤ 500
8x ≤ 500 - 58
8x ≤ 442
x ≤ 442 / 8
x ≤ 55.25
The maximum number of movies Elena can download is 55
Answer:
Step-by-step explanation:
Given that:
X(t) = be the number of customers that have arrived up to time t.
... = the successive arrival times of the customers.
(a)
Then; we can Determine the conditional mean E[W1|X(t)=2] as follows;




Now 
(b) We can Determine the conditional mean E[W3|X(t)=5] as follows;

Now; 
(c) Determine the conditional probability density function for W2, given that X(t)=5.
So ; the conditional probability density function of
given that X(t)=5 is:
