Congress regulates corporate fuel economy and sets an annual gas mileage for cars. a company with a large fleet of cars hopes to meet the 2011 goal of 30.2mpg or better for their fleet of cars. to see if the goal is being met, they check the gasoline usage for 50 company trips chosen at random, finding a mean of 32.12mpg and a standard deviation of 4.83mpg. in this strong evidence that they have attained their fuel economy goal? a. define the parameter and state the hypotheses. b. define the sampling distribution (mean and standard deviation). c. perform the test and calculate p-value d. state your conclusion. e. explain what the p-value means in this context.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
