For the statement? below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify wh
snow_tiger [21]

Answer:

Option E - sigma greater than or equal to $327

Step-by-step explanation:

In this question, we are testing whether the standard deviation of the base price of a certain type of all-terrain vehicle is at least $327.

Now, standard deviation is denoted by the symbol sigma(σ). Since the test is saying it should be at least $327, it means it should either be equal to $327 or greater than $327.

Thus, we would use the symbol ≥ which means "greater than or equal to".

Thus, the claim as a mathematical statement would be;

sigma greater than or equal to $327

Firdavs [7]
To check how much Tim will pay to refill the gas tank using one of the on-site pumps, we can create a linear model. We know from our problem that the Renter's charge $4.50 per gallon plus a $5.00 refueling, so let x be the number of gallons and y the total cost.
y=4.50x+5 
We also know that the fuel tank in the car is half empty and t<span>he car has a 12-gallon fuel tank, so half tank is 6 gallons. Lets replace the number of gallons in our linear model with 6 to fin the total cost: 
</span>y=4.50x+5 
y=4.50(6)+5
y=27+5
y=32

Now, to find how much Tim will pay if he decides to refuel the car on his own, we can also create a linear model.
Let x be the number of gallons and y the total cost. We know form our problem that <span>refueling the car on his own will cost $2.59 per gallon and the late fee charge is $32.
</span>y=2.59x+32
<span>We already know that half tank is 6 gallons, so 
</span>y=2.59(6)+32
y=15.54+32
y=47.54
<span>
Comparing the result of our two linear models we can conclude that the correct answer is: </span><span>b. It would be cheaper to return the car on time and pay the refueling costs.</span>
