Step-by-step explanation:
7*12=84 10:12 chili dogs 10*7=70
We are given the following data
n = 35
x = 50
s = 2
CI = 95% (z = 1.96)
The formula for the margin of error is
E = z s / √n
Substituting the given values
E = 1.96 (2) / √35)
E = 0.66 or 66%
Answer:
- <em>The value of the constant is </em><u>0.8</u>
Explanation:
<em>The graph</em> has the following properties:
- Horizontal-axis (independent variable): width
- Vertical-axis (dependent variable): height
- Points on the curve:
(0.5, 1.6), (0.8, 1), (1.6, 0.5), and (2, 0.4)
<em>The equation</em> represented by the graph is an inverse variation:
- Height = constant / width.
From that equation, you can solve for the contstant:
- constant = height × width
Now, you can take any ordered pair to find the constant:
- (0.5, 1.6) ⇒ constant = 0.5 × 1.6 = 0.8
- (0.8, 1) ⇒constant = 0.8 × 1 = 0.8
- (1.6, 0.5) ⇒ constant = 1.6 × 0.5 = 0.8
- (2, 0.04) ⇒ constant = 2 × 0.4 = 0.8
Thus, you have obtained that the constant is 0.8.
