Answer:
Its either A or C 
Step-by-step explanation: times the 45.00 x 0.15 and then try 45.00 x 1.14 it will give you the answer :D
 
        
             
        
        
        
Answer:
Area= 70x^3y^2
Perimeter = 20x^2 + 14 xy^2
Step-by-step explanation:
Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 .  The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.  
 
        
             
        
        
        
Step 1: Writing Null and Alternate HypothesisFirst we need to write the Null and Alternate Hypothesis for this problem.
Researcher claims that mileage will be increased on addition of Fuel additive. So the null and alternate hypothesis will be:
 : μ ≤ 25.1        (Null Hypothesis)
: μ ≤ 25.1        (Null Hypothesis) : μ > 25.1        (Alternate Hypothesis)
: μ > 25.1        (Alternate Hypothesis)This is a Right Tailed Test. Since population standard deviation is not know, we will use t-test to check the researchers claim.
Step 2: Finding Test StatisticSample Mean = x = 26.8
Standard Deviation = s = 3.9
Sample Size = n = 35 
Degrees of Freedom = df = n - 1 = 34
Test statistic(t) is given by:
 Step 3: Finding p value
Step 3: Finding p valueUsing t table or calculators find the p value for t=2.579 with 34 degrees of freedom for one tailed test.
P value comes out to be:
p = 0.0072
Step 4: ConclusionSince the p value is lesser than the significance level of 0.05, we reject the Null Hypothesis.
We have enough evidence to support the researcher's claim that the new additive increases the miles per gallon of the cars.
