This basically means that you have to multiply the x and y values by 3. So 2 time 3 is 6. And -7 times 3 is -21. So the new coordinations are (6, -21)
Hope this helped and pls mark as brainliest!

Answer:

Step-by-step explanation:
you have that the average sped is given by the following formula:

The uncertainty formula for a division is given by:
(1)
Δv: uncertainty in speed
Δx: uncertainty in the distance = 0.9m
Δt: uncertainty in time = 0.7s
x: distance = 8.1m
t: time = 1.7s
You replace the values of all parameters in the equation (1):

Hence, the relation between the uncertainty in the average velocity is 0.426
The average of the 75 customers will be 6.4.
<h3>How to calculate the value?</h3>
The first 30 customers made an average of 5 claims each. The total claims will be:
= (5 × 30) = 150
When 75 more people were assessed, the average was 6. Therefore, the total claims will be:
= (75 + 30) × 6
= 105 × 6
= 630
Therefore, the average of the 75 customers will be:
= (630 - 150)/75
= 480/75
= 6.4
