Heyo!

Solve the equation

1/3(2x -4) + 5 = -2/3(x +1)

Distribute 1/3 through the parenthesis

2/3x -4/3 + 5 = -2/3(x +1)

Distribute -2/3 through the parenthesis

2/3x -4/3 + 5 = -2/3x - 2/3

Calculate the sum or difference

2/3x + 11/3 = -2/3x -2/3

Multiply both sides of the equation by 3

2x + 11 = -2x -2

Move variable to the left side and change its sign

2x + 2x + 11 = -2

Move constant to the right side and change its sign

2x + 2x = -2 -11

Collect the like terms

4x = -2 -11

Calculate the sum or difference

4x = -13

Divide both sides of the equation by 4

x = -13/4

tamaranim1 [39]
Length should be 2/5yd:

18inch*1yd/36inch=.5yd=> depth

volume= 2(length*width+lenght*depth+depth*width)

let l to be the length.

volume= 2(l*2+2(.5)+.5*2)

volume=5l+2

4=5l+2

2=5l

l=2/5

nata0808 [166]

Answer:

With a .95 probability, the sample size that needs to be taken if the desired margin of error is .04 or less is of at least 216.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

For this problem, we have that:

p = 0.1

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

With a .95 probability, the sample size that needs to be taken if the desired margin of error is .04 or less is

We need a sample size of at least n, in which n is found M = 0.04.

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.04 = 1.96\sqrt{\frac{0.1*0.9}{n}}

0.04\sqrt{n} = 0.588

\sqrt{n} = \frac{0.588}{0.04}

\sqrt{n} = 14.7

(\sqrt{n})^{2} = (14.7)^{2}

n = 216

With a .95 probability, the sample size that needs to be taken if the desired margin of error is .04 or less is of at least 216.

Graph the circle x2 + y2 + 10x + 6y + 18 = 0.
Minchanka [31]

Answer:

  see below for a graph

Step-by-step explanation:

Completing the square for x and y terms can help you put this in the standard form.

  (x^2 +10x) +(y^2 +6y) = -18

  (x^2 +10x +25) +(y^2 +6x +9) = -18 +25 +9 . . . . add square of half linear coefficient

  (x +5)^2 +(y +3)^2 = 16 . . . . . . . circle centered at (-5, -3) with radius 4
