Y = -1

It is an isosceles trapezoid, which is just as well, otherwise it could not reflect onto itself. The line of reflection is the same as the mirror line which is the same as the axis of symmetry.

It runs horizontally exactly through the middle of the shape.

All horizontal lines have the equation y = a value

In this case the line is y=−1

"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 %

A. Describe two ways to find product 4.2 (6+ 0.43)

weqwewe [10]

First method:

What we can do first is to distribute directly 4.2 to 6 and 0.43, that is:

4.2 (6 + 0.43)

= 4.2 * 6 + 4.2 * 0.43

= 25.2 + 1.806

= 27.006

Second method:

We can add the two numbers 6 and 0.43 then multiply with 4.2, that is:

4.2 (6 + 0.43)

= 4.2 (6.43)

= 27.006

What we see is the Distributive Property of multiplication which states that multiplying the sum of a number is similar to multiplying each number and then adding the products.
