Answer:

a. 1.645 multiplier = 5% critical value

b. 95

Step-by-step explanation:

Note that in statistical analysis probability principles are often used. The critical value from the critical region indicates whether the statistician should reject or accept the null hypothesis.

Note that the confidence multiplier is a constant that shows the number of standard deviations in a normal curve; the  deviation standard<em> implies the measure of difference between the observed value of a variable and some another value.</em>

Answer:

The answer is a² .

Step-by-step explanation:

You have to substitute x and y into the expression :

let \: x = a \cos(θ) \\ let \: y = a \sin( θ)

{x}^{2}  +  {y}^{2}  =  {(a \cosθ )}^{2}  +  {(a \sinθ) }^{2}

{x}^{2}  +  {y}^{2}  =  {a}^{2}( {cos}^{2}θ) +  {a}^{2} ({sin}^{2}θ)

Next, you have to apply Basic Trigonometric Identity :

{sin}^{2} θ +  {cos}^{2} θ = 1

{x}^{2}  +  {y}^{2}  =  {a}^{2} ( {cos}^{2} θ +  {sin}^{2} θ)

{x}^{2}  +  {y}^{2}  =  {a}^{2} (1)

{x}^{2}  +  {y}^{2}  =  { a}^{2}

Which graph represents the solution to the given system? y=4x+4 y=4x-3
Burka [1]

Answer:

Refer the attached figure.

Step-by-step explanation:

Given : System of equation y=4x+4,\ y=4x-3

To find : Which graph represents the solution to the given system?

Solution :

Equation y=4x+4 plotted with a red line passing through (-1,0) and(0,4).

Equation y=4x-3 plotted with a blue line passing through (0,-3) and(0.75,0).

As their slopes are equal i.e. m=4.

So, the equation of lines are parallel.

There is no solution of the equations.

Refer the attached figure of the equations.

Solve using elimination.<br> 5x - 6y = 2<br> -5x - 5y = 20
s344n2d4d5 [400]

Answer:

x = -2, y =-2

Step-by-step explanation:

5x - 6y = 2

-5x - 5y = 20

Add the two equations together to eliminate x

5x - 6y = 2

-5x - 5y = 20

------------------------

-11y = 22

Divide by -11

-11y/-11 = 22/-11

y = -2

Now we can find x

5x -6(-2) =2

5x +12 = 2

Subtract 12 from each side

5x +12-12 =2-12

5x = -10

Divide by 5

5x/5 = -10/5

x = -2
