Suppose you draw a single sample of size 64 from a large population and measure its sample proportion. What is the margin of err
MissTica

Answer:

(b) 6.25%

Step-by-step explanation:

Margin of error is the chances of percentage deviation that may differ from original population data. The margin of error for 95% confidence interval can be 6.25%. To find this we divide population standard deviation with square root of sample size. The margin of error is the estimate of the deviation from actual and real value of population.

(2x-7)-(4x^2+6x-3)+(x^2+4)
masha68 [24]

Answer:

-3x^2-4x

Step-by-step explanation:

Simplify:

\left(2x-7\right)-\left(4x^2+6x-3\right)+\left(x^2+4\right)

=2x-7-\left(4x^2+6x-3\right)+x^2+4

Group same factor:

=-\left(4x^2+6x-3\right)+x^2+2x-7+4

Add :

=-\left(4x^2+6x-3\right)+x^2+2x-3

Apply the distributive law: -(a+b) = -a - b

-\left(4x^2+6x-3\right)=-4x^2-6x+3

=-4x^2-6x+3+x^2+2x-3

Group same factor:

=-4x^2+x^2-6x+2x+3-3

Subtract:

=-4x^2+x^2-6x+2x

Add:

=-3x^2-6x+2x

Group same factor:

=-3x^2-4x

Hence answer = -3x^2-4x

What is the slope of the line that passes through the points (-7, -7) and (-7, 1) ?
ICE Princess25 [194]

Answer:

undefined

Step-by-step explanation:

(-7, -7) and (-7, 1)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(1 - (-7)) / (-7 - (-7))

Simplify the parentheses.

= (1 + 7) / (-7 + 7)

Simplify the fraction.

8/0

= undefined

Our line is a vertical line, which has an undefined slope.

Hope this helps!

<span>My answer -
f(x)=x^3+2 To find the inverse function f(x)^-1 , we will assume" y=x^3+2 y-2= x^3 ==> x= (y-2)^1/3 ==> f(x)-1= (x-2)^1/3</span>
P.S
