Answer:
64 miles
Step-by-step explanation:
Number of miles driven in 45 minutes = 48 miles
We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.
Number of miles driven in 1 minute = miles
Since, 1 hour = 60 minutes, we can write:
The number of miles driven in 1 hour (60 minutes) = miles
This means the truck driver can drive 64 miles in an hour.
HOPE THIS HELPS! :)
Answer:
9.5
Step-by-step explanation:
1. Arrange in ascending order
4 5 6 7 8 9 10 11 12
2. Upper Quartile formula:
3×(N+1)÷4
3. Number of terms (N) = 9
4. Apply:
3×(9+1)/4
=3×10/4
=30/4
=7.5th term
5. 7.5th term is the average of the 7th and the 8th term so
Take average
7th term is 9 and 8th term is 10
6. Find average of 9 and 10 = 9.5
7. ANSWER : THE UPPER QUARTILE IS 9.5 FOR THE GIVEN DATA
The left hand side of the equation is a difference of two squares and may be factored out as follows,
(x - 4)(x + 4) > 0
They may be individually taken as,
x - 4 > 0 ; x > 4
x + 4 > 0 ; x < -4
Thus, the answer to this item is letter A.
