Answer:
The correct option is B) 0.0228
Step-by-step explanation:
Consider the provided information.
The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known to be 0.5 minute.
Thus, the value of n = 100, 
and σ = 0.5
We want to test to determine whether or not the mean waiting time of all customers is significantly more than 3 minutes.
The null and alternative hypotheses are,
and 
Compute the test statistic 
By using the table.
P value = P(Z>2) = 0.0228
Hence, the correct option is B) 0.0228

Answer:
Step-by-step explanation:
The two given numbers both have the denominator 5, Thus the quotient quickly reduces:
11 4/5 becomes 59/5 and 3 1/5 becomes 16/5. Dividing the first expression by the second yields 59/16, which can't be reduced.
However, 59 = 48 + 11, so 59/16 = 48/16 + 11/16, which is approximately 3 1/2 (from either Answer B or Answer C).
The exact answer is 3 11/16; B and C are identical and are closer to 3 11/16 thn 3 or 4.
Answer:
2w^2 + 34w
Step-by-step explanation:
2w(w+17)
Multiply the 2w by each term in the parentheses
2w*w + 2w*17
2w^2 + 34w
