Answer:

0.4082

Step-by-step explanation:

Data

mean (\mu) = 50,000 miles

standard deviation (\sigma) = 12,000 miles

expected distance (X) = 34,000 miles

In the figure attached, standard normal distribution table can be seen. Z is computed as follows:

Z = \frac{X - \mu}{\sigma}{

Z = \frac{34000 - 50000}{12000}{

Z = -1.33{

In standard table, the area between 0 and -1.33 is the sem as between 0 and 1.33. So, the proportion of trucks is 0.4082

A dealer paid $10,000 for a boat at an auction. At the dealership, a sales person sold the boat for 30% more than the auction pr
vazorg [7]
30% of 10,000 is 3,000, so the salesperson would have sold the boat for $13,000. The difference between the auction price and dealership price is 3,000. The commission is 25% of 3,000, which is $750.

Is the system of equations is consistent, consistent and coincident, or inconsistent? y=−12x+3y=4x+2 Select the correct answer f
Ksju [112]
A consistent system has at least one solution. ... y = 7/3 * x - 2/3 is the slope intercept form of the equation 7x - 3y = 2 m = 7/3 b = -2/3 a line parallel to the line created by this equation will have the same slope but a different y-intercept.
