Answer:
I think they are independent
Step-by-step explanation:
Answer:
46.2 mi is the right answer.
Step-by-step explanation:
In this question we will follow the property of congruence of two triangles.
Here two triangles formed are triangle formed by Alba, Cray and Blare and a triangle formed by Service station, Cray and Blare.
The distance between Alba and Blare = 130 mi
The distance between Alba and Cray = 120 mi
As we know in the congruent triangles all sides are in the same ratio.
Now we apply the property of the theorem



x = 46.2 mi
Step-by-step explanation:
100*77+72/4
100*77+18
7700+18
7718
Independent because the ratio of the second cube is the same (1:6), and it isn't affected by the result of the first cube
Answer:
A
The test statistics is 
B
The Null and Alternative hypothesis are
and 
Step-by-step explanation:
From the question we are told that
The population mean is 
The sample size is 
The sample mean is 
The sample standard deviation is 
The level of significance is 
Given that the value which the manufacturer gave the automobile is 47.2 and it is believed that this is not correct, then
The Null Hypothesis is

The alternative Hypothesis is

The test statistics can be mathematically evaluated as

substituting values
