In a recent survey of 79 heads of household, 46 said they did online banking on their cell phones. Find the standard error for the sample proportion of heads of household who do online banking on their cell phones. Enter your answer as a decimal rounded to three decimal places.

Answers

Answer 1

Answer:

[tex]SE_p = 0.055[/tex]

Step-by-step explanation:

Given

[tex]n = 79[/tex] --- Heads

Proportion, p = 46 out of 79

Required

Determine the standard error for sample proportion (SEp)

This is calculated using the following formula

[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this case:

[tex]p = \frac{46}{79}[/tex]

[tex]p = 0.5823[/tex]

Substitute values for p and n in:

[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * (1-0.5823)}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * 0.4177}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.24322671}{79}}[/tex]

[tex]SE_p = \sqrt{0.00307881911}[/tex]

[tex]SE_p = 0.0554871076[/tex]

[tex]SE_p = 0.055[/tex] ---- Approximated

Find the degree measure of the angle with the given radian measure. (Round your answer to one decimal place.)

Answers

Answer:

108 degrees

Step-by-step explanation:

Since we are not given the radian measure. Let the radian measure be 3π/5 rad;

Using the conversion;

πrad = 180°

3π/5 rad = x

Cross mulriply;

π * x = 180 * 3π/5

x =  180 * 3/5

x = 36 * 3

x = 108 degrees

Hence the degree measure is 108 degrees

Note that the same conversion can be used to convert other values in radians

a²b is the same thing as ba²

b and a are two separate variables lets pretend a is 2 and b is 3

2² * 3 = 4 * 3 = 12

3 * 2² = 3 * 4 = 12

this is the commutative property of multiplication

An expression is defined as a set of numbers, variables, and mathematical operations. The two of the given expressions a²b and ba² are the same.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The two of the given expressions a²b and ba² are the same because if the two of the expressions are expanded then the value of the two expressions will be equal to each other.

Therefore, the two expressions are expanded as shown below,

a²b = a × a × b

ba² = b × a × a

Therefore, the two of the given expressions a²b and ba² are the same.

There can be only 1 triangle formed by the given information.

What is triangle?

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

Given that, ABC can be formed if C=60∘, c=17√3 and a=34
