Explanation:
The <em>arc length</em> of a <em>circular </em>sector is related to the <em>swept angle</em> by the proportion:
Here you have:
- arc length: ?
- radius: 48 inches
- angle: 225º
Substitute and solve for the arc length:
In inches:
inches
Convert to feet:
Use the conversion factor: 1 feet = 12 inches
4) 41/4, 14/4, 55/6, 34/7,60/8, 47/9, 27/6, 48/5, 31/3, 50/7,
5a) 132/6= 22
b) 146/9= 16.22
c) 147/2= 73.5
d) 107/4= 26.75
e) 156/8 = 19.5
f) 148/9 = 16.44
ANSWER
8 units.
EXPLANATION
The first point, A is located at (-9,2) on the coordinate plane.
The second point, B is also located at (-9,10) on the coordinate plane.
You should be smart and observe that the x-coordinates of both points are the same. This means that, the two points lies on a vertical line.
Hence it will be faster to use the absolute value method rather than the distance formula.
According to this method, you only have to find the absolute value of the difference in the y-values.
Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation
Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320
The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).
