Answer:
≈ -0.821
Step-by-step explanation:
<u>Given:</u>
- n= 380, sample
- x= 19, no-shows count
- p = 0.06, proportion of no-shows
<u>Then, the sample proportion is:</u>
- p' = x/n = 19/ 380 = 0.05
<u>Hypothesis test:</u>
<u>Test statistics:</u>
- z = (p' - p) /
- z = (0.05 - 0.06)/
≈ -0.821

Step-by-step explanation:
y = 2x + 1
so you want the coordinates (1,3)
so you input the x coordinate into the equation,
y = 2(1) + 1
y = 2 + 1
y = 3
but if you have to write a new equation to get coordinates (1,3)
you could write the equation
y = 3x
The standard equation for an ellipse is
where
(h,k) = coordinates of the center
a, b = semi-major and semi-minor axes
Refer to the figure shown below.
The center of the ellipse is at (0,0).
Therefore, h=0, k=0.
One focus is at (12, 0)
Therefore
c = 12
One directrix is at 14 1/12 = 169/12.
Because the directrix is located at x = a²/c, therefore
a²/12 = 169/12
a² = 169/144
a = 13
Because c² = a² - b², obtain
b² = a² - c²
= 169 - 144 = 25
b = 5
