Answer:
This is strong evidence that more than 2% get damaged
Step-by-step explanation:
The company goal is to keep the proportion of damaged machines below 2%
One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents
So, x = 6
n = 66
Formula : 
So, the value of test statistic is 4.114
2) What is the P-value of the test statistic?
So, p value using calculator = .00002
p value < α
So, we accept the alternate hypothesis
So, This is strong evidence that more than 2% get damaged
The points which satisfy the inequalities in discuss are; Choices D (7,10) and F(8,17).
<h3>Which points omg the answer choices satisfy the system of inequalities?</h3>
It follows from the inequality; x > 5.
Also, substituting 5 for x in; y < 2(x); we have;
y < 10.
Hence, the points which satisfy the inequalities are; (8,17) and (7,10).

Average speed of the entire journey is 3.08 km/hr
Step-by-step explanation:
- Step 1: In the first half, given that the speed = 4 km/h and time = 2 1/2 = 2.5 hrs. Calculate the distance covered.
Distance = Speed × Time = 4 × 2.5 = 10 km
- Step 2: In the second half, given that speed = 2 1/2 = 2.5 km/hr and time = 4 hrs. Calculate the distance covered.
Distance = 2.5 × 4 = 10 km
- Step 3: Calculate average speed.
Average Speed = Total distance/Total time
= 10 + 10/2.5 + 4 = 20/6.5
= 3.08 km/hr
