Answer:
a) 4
Step-by-step explanation:
Take the equation:
x + 1483 = 2113.833
Solve for x:
x = 2113.833 - 1483
x = 630.833
To find df, take the equation:
Where x = 630.833
Solve for y:
y ≈ 3
Take number of treatments = k
Degrees of freedom, df, of numberof treatments = k - 1
Therefore,
Where df = 3, we have:
k - 1 = 3
Solve for k:
k = 3 + 1
k = 4
The number of treatment groups is 4
Answer:
x = -3
y = 3
Step-by-step explanation:
<u>Step 1</u>
X = 15 - 6y
<u>Step 2</u>
Replace x with 15 -6y in the second eqation
3(15 - 6y) + 4y = 3
45 - 18y + 4y = 3
45 - 3 = 18y - 4y
42 = 14 y
y= 3
find x:
X = 15 - 6(3)
x = -3
Answer:
a
Step-by-step explanation:
Answer:
General solution is
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given cos x - sin x = √2 cos (3 x)
Dividing '√2' on both sides , we get
we will use trigonometry formulas
a) Cos ( A + B) = Cos A Cos B - sin A sin B
b)
<u><em>Step(ii):-</em></u>
