Answer:

K = 12, so the correct answer is D.

Step-by-step explanation:

- \frac{5}{6}K = -10

-5K = -60 (Multiply 6 to both sides)

K = 12 (Divide both sides by 5)

D. 12 is your answer

To get rid of the -5/6, you Have to multiply both sides of the equation by it’s inverse, which is -6/5.

-10 x -6/5 = 60/5 = 12

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

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

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

In this problem, we have a 90% confidence level, hence\alpha = 0.9, z is the value of Z that has a p-value of \frac{1+0.9}{2} = 0.95, so the critical value is z = 1.645.

The sample size and the estimate are given by:

n = 600, \pi = \frac{400}{600} = 0.6667

Hence, the bounds of the interval are given by:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 - 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6350

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 + 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6984

The 90% confidence interval is given by: (0.6350, 0.6984).

What is the perimeter of a rectangle is 154 feet. the length of the rectangle is 55 feet. what is the width of the rectangle? th
velikii [3]
Perimeter= (2 x Length) + (2 x width)
Do to find width:
Width= perimeter - (2 x length)
So now substitute in an equation
W= 154 - (55 x 2)
W= 154-110= 44
Remember 44 would equal the width when it is multiplied by 2. Now you have to divide by 2 to get the original.

olya-2409 [2.1K]
This is a 30-60-90 triangle
opposite side of rigt angle=2x
opposite side of 60 degrees is x√3
opposite sides of 30 degree is x
the right angle is at the base of the building so therefor
200=x
2x=distance from surveor to top of building and x√3=height of building

x=200
200√3≈346.41

the answer is 346.41 feet

What is the volume of this rectangular prism?
frutty [35]

Answer:

There is no correct answer. Volume = length x width x height.

Step-by-step explanation:

14 x 4 x 9 = 504. I would pick C. 144in ^3 because it's closest to 504 but I'm not sure.
