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

A train travels 250 km with a average speed of 75 km/hr and 350 km with 70km/hr and 200 km with average speed of 30km/hr. What w
pentagon [3]

Answer:

53 1/3 km/h

Step-by-step explanation:

average speed = (total distance)/(total time)

average speed = distance/time

time * average speed = distance

time = distance/(average speed)

250 km at 75 km/h

distance = 250 km

time = (250 km)/(75 km/h) = 3.33333... hours

350 km at 70 km/h

distance = 350 km

time = (350 km)/(70 km/h) = 5 hours

200 km at 30 km/h

distance = 200 km

time = (200 km)/(30 km/h) = 6.6666...  hour

total distance = 250 km + 350 km + 200 km = 800 km

total time = 3.33333... hours + 5 hours + 6.66666... hours = 15 hours

average speed = (total distance)/(total time)

average speed = (800 km)/(15 hours)

average speed = 53 1/3 km/h

Using a table of values what is the solution to this equation <br>7/x+2 = log(x+5)​
Pani-rosa [81]

Answer:

D. 5

Step-by-step explanation:

let x = 5,

=> log (x+5) = log (5+5) = log 10 = 1

=> 7/(x+2) = 7/(5+2) = 7/7 = 1

so, 7/(x+2) = log(x+5)
