Plugging in 0 doesn't work so you can automatically rule out option D. 

Plugging in 1 is an easy one. 5.6 + 0.4(1) is 5.6 + 0.4 = 6. 6(1) is also 6. This rules out option A.

Now all we have to do is plug in 0.875 to see if it works. If it does, option C is the answer. If not, well... only leaves option B. 

5.6 + 0.4(0.875) = 5.6 + 0.35 = 5.95 

6(0.875) = 5.25 

So 0.875 does not make the statement true. 

Your answer is Option B.

Lisa paid 43.95 for 16.1 gallon of gasoline. What was that cost per gallon rounded to the nearest hundredth
djverab [1.8K]

Answer:

2.73

Step-by-step explanation:

It is given that Lisa paid 43.95 for 16.1 gallons of gasoline.

So, the cost of 16.1 gallons of gasoline is 43.95.

Hence, the cost of gasoline per gallon is 43.95/16.1 = 2.7304347.

Now, it is required to round this value to the nearest hundredth.

Therefore, the cost of gasoline per gallon rounded to the nearest hundredth is 2.73. (Answer)

aleksandrvk [35]
The mean proportion is p = 36/120 = 0.3.
The standard deviation of the proportion will be sqrt(p*(1-p)/n) = sqrt(0.3*0.7/120) = 0.0418. We multiply this by the z-score of 1.645 to get a deviation of 0.0688.
Therefore, the confidence interval is (0.3 - 0.0688, 0.3 + 0.0688), which is
(0.2312, 0.3688).
