Answer:
Option B
Step-by-step explanation:
As per the question:
The variance of the 48 Econ 202, = 16 inches
The variance of 63 Econ 203 = 14 inches
Now, to test the variance of two populations:
For 48 Econ 202:

For 63 Econ 203:

On comparing the two, the test statistics is given by;
F = 
F = 
The shifts of the sinus function can be described with the formula:
<span>a<span>sin<span>(<span><span>bx</span><span>−c</span></span>)</span></span></span>+<span>d, where
a is the amplitude
b is the period
c is the phase shift
d is the vertical shift
So, the graph y=3sinx is phase shifted. The phase shift can be calculated as c/b= pi/3/1=pi/3
So, the function is phase shifted for pi/3.</span>
Answer:
Angle 1 = 35
Angle 2 = 70
Angle 3 = 75
Step-by-step explanation:
Let's define Angle 1 as <em>x</em>
<em />
Angle 1 = x
Angle 2 = 2x
Angle 3 = 2x + 5
x + 2x +2x + 5 = 180
5x + 5 = 180
5x = 175
x = 35
Angle 1 = 35
Angle 2 = 70
Angle 3 = 75
