The midpoint of  is point P at (−6,−2). If point E is at (2,−4), what are the coordinates of point F?
Shtirlitz [24]

F would be (-14, 0)

In order to find this, we first have to note that the coordinates of P would simply be the average of it's E and F counterparts. We'll first start by finding the x value.

(Ex + Fx)/2 = Px

(2 + Fx)/2 = -6

2 + Fx = -12

Fx = -14

Now we'll do the same for the y coordinate.

(Ey + Fy)/2 = Py

(-4 + Fy)/2 = -2

-4 + Fy = -4

Fy = 0

The owner of a large car dealership believes that the financial crisis decreased the number of customers visiting her dealership
Setler79 [48]

Answer:

H0: μ = 800

Ha: μ < 800

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

For the case above;

Let μ represent the average number of customers visiting the dealership per day

The null hypothesis is that the average number of customers visiting the dealership per day is equal to 800

H0: μ = 800

The alternative hypothesis is that the average number of customers visiting the dealership per day is less than 800

Ha: μ < 800
