The formula for the confidence interval is given by

Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]

We have:
Sample mean = 23.95
n = 40 
σ = 2.55
z* for 99% confidence = 2.58

Substitute these values into the formula, we have

23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91

So the lower interval is 22.91 and the highest interval is 24.99

Factor the polynomial.
mixer [17]

Answer:

Final answer is choice B. (5x-2y)^2

Step-by-step explanation:

We need to factor the given expression 25x^2-20xy+4y^2

25x^2-20xy+4y^2

=25x^2-10xy-10xy+4y^2

=5x(5x-2y)-2y(5x-2y)

=(5x-2y)(5x-2y)

=(5x-2y)^2

Hence final answer is choice B. (5x-2y)^2
