l is ($45,700, $59,150). Braxton is conducting a test of the null hypothesis H0: µ = 44,000 against the alternative hypothesis Ha: µ ≠ 44,000 at the α = 0.08 level of significance. Does Braxton have enough information to conduct a test of the null hypothesis against the alternative?
multiple-choice options:
H0: µ > 17 miles per gallon, Ha: µ ≥ 17 miles per gallon

H0: µ ≤ 17 miles per gallon, Ha: µ < 17 miles per gallon

H0: µ = 17 miles per gallon, Ha: µ > 17 miles per gallon

Which rule describes the relationship between the x- and y- coordinates on line m?
const2013 [10]

Answer:

y = 2x - 1

Step-by-step explanation:

None of those would be correct, the line on the graph is y = 2x - 1 because the slope of the line is 2 and the y -intercept -1.

You can also check, we know that on the graph the coordinates where the dots are located are: (2,3),(3,5),(4,7) where the first number is x and second is y coordinate.

Check answer:

Let x=2 if this is correct y should be equal to 3 because of the first point (2,3).

y = 2(2)-1 = 4 - 1 = 3

check the other points if you want to confirm.
