WILL GIVE BRAINLIST!!!!!!!FACTOR THIS COMPLETELY 4x^2 − 25

Mathematics
1 answer:
Wittaler [7]3 years ago
3 0

Answer:

(2x - 5)(2x +5)

Step-by-step explanation:

4x^2 is a perfect square with a square root of 2x, and 25 is also a perfect square with a square root of 5. The difference of two perfect squares a and b can be written as (\sqrt{a} - \sqrt{b} )(\sqrt{a} +\sqrt{b} ). So, 4x^2 - 25 can be factored into (2x-5)(2x+5).

Hope that helped! ;)

"Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given st
11111nata11111 [884]

Answer:

The error E = ± 4.04 %

Step-by-step explanation:

Solution:-

- The sample data is used to estimate the population proportion ( p ).

- The success p^ = success percentage = 40 %

- The confidence interval CI = 98%

- The sample size n = 800

- The margin of error E:

- The margin of error "E" for estimation of population proportion ( p ) is given by:

                          E = z-critical*\sqrt{\frac{p~ ( 1 - p~ )}{n} }

Where, Z-critical value is defined by the significance level:

                         P ( Z < Z-critical ) = α / 2

Where, α : Significance level

                          α = 1 - CI

                         P ( Z < Z-critical ) = (1 - 0.98) / 2

                         P ( Z < Z-critical ) = 0.01  

                         Z-critical = 2.33

- The error E of estimation is:

                        E = 2.33*\sqrt{\frac{0.4 ( 1 - 0.4 )}{800} }\\\\E = 0.04035

- The error E = ± 4.04 %
