Use the formulav = u+at to find the velocity • the initial velocity is 3 m/s
• the acceleration is 1.5 m/s²
• the time is 7 seconds

The final velocity is 13.5 m/s.

Step-by-step explanation:

Given :

To Find :

Using Formula :

Solution :

Substituting all the given values in the formula to find Final velocity :

Hence, the final velocity is 13.5 m/s.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
