<span>(-2/3)*(w-(4/9)) = -4/3 // + -4/3
(-2/3)*(w-(4/9))-(-4/3) = 0
(-2/3)*(w-4/9)+4/3 = 0
4/3-2/3*(w-4/9) = 0
(-2/3*3*(w-4/9))/3+4/3 = 0
4-2/3*3*(w-4/9) = 0
44/9-2*w = 0
(44/9-2*w)/3 = 0
(44/9-2*w)/3 = 0 // * 3
44/9-2*w = 0
44/9-2*w = 0 // - 44/9
-2*w = -44/9 // : -2
w = -44/9/(-2)
w = 22/9
w = 22/9</span>
Answer:
5
Step-by-step explanation:
The function 
is
- decreasing for all
- is increasing for all
![x\in (0,2]](https://tex.z-dn.net/?f=x%5Cin%20%280%2C2%5D)
(see attached diagram for details).
The maximum value of the function is at endpoints -3 or 2. find y(-3) and y(2):
So, the maximum value is 5.
The alternative and null hypotheses is given below,
Null Hypothesis, H0: μ1 - μ2 = 0
Alternative Hypothesis, Ha: μ1 - μ2 < 0
Compound Variance is given as,
sp = sqrt( s12n1+s22n2)
sp = sqrt(16973 + 112.3673)
sp = 1.9632
Test statistic of z is,
z = (x1bar - x2bar)/sp
z = (69 - 71)/1.9632
z = -1.02
P-value Approach, P=0.1539 as long as P>= 0.
As P-value >= 0.01, failing to rule out the null hypothesis.

What is known as a decimal mark?</h3>
To differentiate between a whole number and its fractional component, a decimal point is used either as a point or a dot. It is also referred to as a decimal mark. The symbol for the decimal point is (.). In daily life, decimals are also frequently used. That whenever a shirt costs $10.50, for instance, the price can be written as 10.50.

Answer:
x^2 - 2xy + y^2.
Step-by-step explanation:
(x - y)^2
= (x - y)(x - y)
= x(x -y) - y(x - y)
= x^2 - xy - xy + y^2
= x^2 - 2xy + y^2.
