Step-by-step explanation:
Mean=sum of terms/ number of terms
22+23+25+17+18/5
105/5
21
Finding the age of the sixth person
105+x/6=24
105+x=24x6
105+x=144
x=144-105
x=39
The answer is
3 + (2) (4) - 4
answer is 7

Answer:
The answer to your question is 450 km
Step-by-step explanation:
Data
First stage Second stage
speed 1 = 40 km/h speed 2 = 65 km/h
time 1 = 8 h time 2 = 2 h
Process
1.- Write the formula to calculate the speed
speed = distance / time
-Solve for distance
distance = speed x time
2.- Calculate the distance of the first stage
distance 1 = 40 x 8
distance 1 = 320 km
3.- Calculate the distance of the second stage
distance 2 = 65 x 2
distance 2 = 130 km
4.- Calculate the total distance
Total distance = 320 + 130
= 450 km
Yes, because the ratios are equivalent between each pair of values.
