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

Step-by-step explanation:
Answer:
[0.4,4]
Explanation:
The get the values of y belonging to the given interval, we will simply solve the following inequality:
-5 ≤ 5y - 7 <span>≤ 13
-5 + 7 </span>≤ 5y <span>≤ 13 + 7
2 </span>≤ 5y <span>≤ 20
2/5 </span>≤ y <span>≤ 20/5
0.4 </span>≤ y <span>≤ 4
Hope this helps :)</span>
I guess you want to find the average speed for the whole journey
average speed = distance travelled / time
the distance from home to the shop = speed * time = 0.5*10 = 5 miles
time for travelling back = distance / speed = 5/30 = 1/6 hours
average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
