We can use the concept of commutative property of addition here. We know that the addition follow the commutative property.
The commutative property of addition is given by
It means, if we change the order, it will not affect the result.
Therefore, using above mentioned property, we can see that
1+7 = 7+1
Hence, if we know the value of 1+7, then we can easily find the value of 7+1 because both are same.
Answer: 0.0062
Step-by-step explanation:
Given : The weight of trucks traveling on a particular section of I-475 have a population mean of tons and a population standard deviation of
tons.
Sample size : n=49
Let x be the random variable that represents the weight of trucks .
z-score :
For x= 14.3 tons
Now, the probability a state highway inspector could select a sample of 49 trucks and find the sample mean to be 14.3 tons or less will be :-
Hence, the probability a state highway inspector could select a sample of 49 trucks and find the sample mean to be 14.3 tons or less =0.0062
